Maternal & Child Practice Exam 6

EXPLANATION

✔Correct answer:

Transverse palmar crease. A transverse palmar crease, also known as a "simian crease," is a single crease that runs across the palm of the hand. This characteristic is commonly observed in individuals with Down syndrome, although it can also be present in individuals without Down syndrome. In combination with other physical features, the presence of a transverse palmar crease can support the suspicion of Down syndrome in a newborn. Down syndrome, or trisomy 21, is associated with a set of characteristic physical features and developmental delays due to an extra chromosome 21.

Think of the transverse palmar crease as a “clue” in a puzzle. On its own, it might not mean much, but when it appears alongside other features like low muscle tone and distinct facial characteristics, it can help complete the picture indicating Down syndrome.

When assessing a newborn for signs of Down syndrome, Nurse Laura should be mindful of other common physical characteristics to gather a complete picture. Here are some additional signs to look for:

• Look for characteristic facial features, such as an upslanting palpebral fissure (upward slant of the eyes), flat nasal bridge, and small, low-set ears.
• Observe for hypotonia (low muscle tone), which is common in infants with Down syndrome and may affect feeding and movement.
• Check for other common features such as a small mouth with a relatively large tongue (macroglossia), short neck, and broad hands with short fingers.
• Collaborate with a pediatrician or genetic specialist for further evaluation, which may include chromosomal testing to confirm the diagnosis of Down syndrome.
• Provide supportive resources and information to parents, as a suspected diagnosis of Down syndrome can be overwhelming.

✘Incorrect answer options:

Small tongue. Children with Down syndrome typically have a relatively large tongue (macroglossia) in relation to their mouth, which can sometimes protrude. A small tongue is not a characteristic feature of Down syndrome.

Prominent, large nose. Children with Down syndrome usually have a flat nasal bridge rather than a prominent, large nose. A flat nasal bridge is one of the characteristic facial features associated with Down syndrome.

Limited joint movement. In fact, infants with Down syndrome often have increased joint flexibility or hypermobility due to hypotonia (low muscle tone). Limited joint movement would be atypical and is not associated with Down syndrome.

EXPLANATION

✔Correct answer:

Profuse watery diarrhea. Celiac crisis is a rare but severe complication of celiac disease, often triggered by infections, stress, or dietary gluten exposure. It is characterized by sudden, severe symptoms that result from intense malabsorption and fluid loss. Profuse watery diarrhea is a hallmark sign of celiac crisis, as the damaged intestinal lining leads to significant fluid loss and electrolyte imbalance. This can quickly lead to dehydration and metabolic disturbances, requiring urgent medical intervention to stabilize the patient.

In a celiac crisis, the body's immune reaction to gluten or another stressor causes widespread inflammation and damage to the villi in the small intestine. This severely impairs nutrient and fluid absorption, leading to massive, watery diarrhea, dehydration, hypokalemia, and metabolic acidosis. These symptoms can be life-threatening if not managed promptly with fluids, electrolyte replacement, and supportive care.

Imagine the small intestine as a sieve with tiny holes that allow just the right amount of water and nutrients to pass through. In a celiac crisis, the “holes” in the sieve get damaged and enlarged, causing fluids to leak out excessively and leading to profuse watery diarrhea.

When managing a child with celiac crisis, Nurse Karen should focus on interventions to stabilize the patient and address dehydration and electrolyte imbalance.

• Monitor vital signs closely, especially heart rate and blood pressure, to assess for signs of dehydration and hypovolemia.
• Administer intravenous fluids and electrolyte replacements as prescribed to correct fluid and electrolyte deficits.
• Assess the child’s intake and output rigorously, noting the frequency, volume, and consistency of stools.
• Provide a gluten-free diet and avoid any foods that could exacerbate symptoms.
• Educate the family on the importance of strict adherence to a gluten-free diet and recognizing early signs of celiac crisis to prevent recurrence.

✘Incorrect answer options:

Difficulty breathing. Difficulty breathing is not typically associated with celiac crisis. Respiratory distress may be a symptom of other complications or conditions, but it is not a direct effect of celiac disease or its acute crisis state.

Extreme lethargy. While extreme lethargy or weakness may occur as a secondary symptom due to dehydration or electrolyte imbalance, it is not the primary indicator of celiac crisis. Profuse diarrhea is the most distinctive and urgent sign.

Unusual weight gain. Weight gain is not a symptom of celiac crisis. In fact, children with celiac crisis may experience weight loss due to malabsorption and excessive fluid loss.

EXPLANATION

✔Correct answer:

"I know what steps to take to reduce a fever." Mild fever is a common side effect after vaccinations, including the DTP (diphtheria, tetanus, and pertussis) vaccine. It is important for parents to understand how to manage a low-grade fever at home, as it helps keep the child comfortable. Typical home care measures include giving age-appropriate doses of acetaminophen or ibuprofen (if recommended by a healthcare provider), keeping the child hydrated, and dressing them in light clothing. Nurse Emily should ensure that Mrs. Lopez understands how to monitor and manage fever effectively and knows when to seek medical attention if the fever is high or persistent.

Think of post-vaccine fever as a small fire. Just as you would take steps to cool a fire down, like pouring water or moving it to a safe area, managing fever involves simple, calming measures like fluids and fever-reducing medications to keep it in check.

When educating parents on post-vaccination care, it’s essential to focus on common side effects and their management. Here are some key points Nurse Emily should discuss:

• Instruct parents on the use of acetaminophen or ibuprofen for fever management, including correct dosing based on the child’s age and weight.
• Encourage parents to keep the child well-hydrated, as fever can increase fluid needs.
• Advise parents to dress the child in light clothing to prevent overheating and to monitor the child’s comfort level.
• Educate parents on the signs of more serious side effects, such as a high fever (above 102°F or 39°C), excessive irritability, or signs of an allergic reaction (e.g., difficulty breathing, hives), and emphasize the importance of seeking medical attention if these occur.
• Provide reassurance that mild fever and soreness at the injection site are normal and usually resolve within a day or two.

✘Incorrect answer options:

"I understand the need for dietary restrictions." There are no dietary restrictions required following a DTP vaccination. This response would indicate a misunderstanding, as typical post-vaccination care does not involve any changes to diet.

"I am aware of what causes a rash afterward." While mild redness or swelling at the injection site is common, a generalized rash is not a typical reaction after a DTP vaccine. If a rash does occur, it may indicate an allergic reaction or another issue, and medical advice should be sought. This response would indicate a misunderstanding of common vaccine reactions.

"I know how to manage any diarrhea that may occur." Diarrhea is not a common side effect of the DTP vaccine. Common reactions are usually mild fever, soreness at the injection site, and occasionally irritability. If diarrhea does occur, it is likely unrelated to the vaccine, so this response would indicate a lack of understanding of typical post-vaccination side effects.

EXPLANATION

✔Correct answer:

The shorter urethra in females. One of the primary predisposing factors for urinary tract infections (UTIs) in females is the shorter urethra, which allows bacteria easier access to the bladder. In females, the urethra is closer to the anus, increasing the likelihood of bacteria (particularly E. coli, which is commonly found in the intestinal tract) migrating from the perineal area to the urinary tract. This anatomical difference makes females, including young girls like Emma, more susceptible to UTIs than males. In developing her teaching plan, Nurse Kim should educate Emma and her caregivers on hygiene practices and behaviors that can help reduce the risk of future UTIs.

Think of the urinary tract like a road that bacteria can travel along. In females, this "road" (the urethra) is shorter, making it easier and faster for bacteria to reach the bladder, increasing the chance of infection.

When educating a young female patient with a UTI, it's essential to emphasize practices that reduce bacterial exposure and promote bladder health. Here are some key points Nurse Kim should include:

• Teach proper wiping technique: front to back, to prevent bacteria from the anal area from spreading to the urethra.
• Encourage regular bladder emptying, as holding urine can contribute to bacterial growth in the bladder.
• Advise on adequate fluid intake, as drinking plenty of water helps flush bacteria from the urinary system.
• Discourage bubble baths and other irritants that can affect the urethral area, as these may increase the risk of infection.
• Encourage wearing cotton underwear and avoiding tight clothing, which helps prevent moisture buildup that can promote bacterial growth.

✘Incorrect answer options:

The habit of frequently emptying the bladder. Frequent bladder emptying is actually a protective factor against UTIs, as it helps flush out bacteria before they can establish an infection. Holding urine for prolonged periods is a risk factor, not frequent emptying.

Increased daily fluid intake. Increased fluid intake is typically beneficial, as it encourages regular urination and helps to flush bacteria from the urinary tract. Reduced fluid intake, on the other hand, can increase the risk of UTIs by allowing bacteria to concentrate in the bladder.

Consumption of acidic juices. While acidic juices (like cranberry juice) are sometimes recommended as part of UTI prevention due to their potential role in preventing bacteria from adhering to the bladder wall, they are not a predisposing factor for UTIs. In fact, cranberry juice may provide some protection, although evidence is limited. Acidic juices do not increase the risk of UTIs.

EXPLANATION

✔Correct answer:

They sit side by side, each playing with their own doll. Parallel play is a typical form of play for toddlers, where children play next to each other without directly interacting or attempting to influence each other's play. They are engaged in separate activities with their own toys but are in close physical proximity. This type of play is common in early childhood as children begin to develop social awareness but are not yet ready for cooperative play, where they would actively engage in shared activities. In this scenario, each child is playing independently with their own doll while sitting side by side, demonstrating classic parallel play.

Imagine two adults reading different books while sitting next to each other in a coffee shop. They are aware of each other's presence but are focused on their own activity. Similarly, toddlers in parallel play sit near each other but play separately.

When observing and encouraging healthy play among toddlers, it’s essential for Nurse Jamie to recognize that parallel play is developmentally appropriate for this age group. Here are some ways to support toddlers in play:

• Encourage a safe and engaging environment where toddlers have access to a variety of toys they can play with individually, yet alongside other children.
• Observe the toddlers' behaviors and provide positive reinforcement for independent play, while also encouraging gradual social interaction.
• Introduce toys that can be enjoyed side by side, such as blocks, cars, or crayons, to facilitate parallel play in close proximity.
• Model simple social behaviors, like saying “hello” or showing toys to others, to gently encourage social development without forcing direct interaction.
• Provide reassurance to parents that parallel play is a normal part of toddler development, which will eventually progress to more interactive forms of play as the child grows.

✘Incorrect answer options:

Each child is using their own crayons to color separate pictures. While this option describes individual activity, it does not clearly demonstrate the close physical proximity typical of parallel play. Toddlers in parallel play usually play close together with similar or different toys, rather than being physically separated or focused on structured activities like coloring.

They are playing a board game together with the nurse. Playing a board game together involves cooperative play, where children interact, share, and take turns. Cooperative play typically develops later in early childhood, around the preschool years. It requires more advanced social skills than parallel play.

They are taking turns sharing their dolls with different nurses. Taking turns and sharing involves associative play, where children begin to engage with each other’s activities but without a common goal. This form of play indicates a higher level of social interaction and is not typical of parallel play.

EXPLANATION

✔Correct answer:

Impaired oral mucous membranes. "Impaired oral mucous membranes" would be an inappropriate nursing diagnosis for an infant with gastroesophageal reflux (GER). GER primarily affects the gastrointestinal system and involves the backward flow of stomach contents into the esophagus due to a weak or immature lower esophageal sphincter. This condition leads to symptoms like spitting up, irritability after feeding, and possible aspiration risks, but it does not typically result in direct issues with the oral mucosa. GER does not inherently cause dryness, lesions, or breakdown of the oral mucous membranes.

GER in infants is often due to an immature gastroesophageal junction, which allows stomach contents, including acid, to flow back up into the esophagus. While this can cause discomfort, crying, and feeding issues, it does not directly impact the condition of the oral mucous membranes. Impaired oral mucous membranes would more commonly be associated with dehydration, certain infections, or physical trauma to the mouth area.

Imagine GER in an infant like a cup filled with too much water that has a loose lid. Every time you tip the cup even slightly, some water spills out. In this analogy, the stomach is the cup, the loose lid is the weak esophageal sphincter, and the spilled water is the stomach contents that come back up into the esophagus. Just like how water spilling out of the cup can make a mess, the refluxed stomach contents can cause discomfort, risk of aspiration, and interfere with feeding—but they don’t damage the outside of the cup (or the infant's mouth), which is why "Impaired oral mucous membranes" isn’t an appropriate diagnosis for GER.

Nurses caring for infants with GER should focus on the primary issues associated with reflux, such as nutritional support and aspiration prevention, rather than concerns related to oral mucosa.

• Encourage small, frequent feedings to reduce reflux episodes.
• Position the infant in an upright position after feedings to minimize the likelihood of regurgitation and aspiration.
• Monitor the infant’s growth and weight gain to assess for signs of nutritional imbalance.
• Educate parents on safe sleep practices, as well as techniques to reduce reflux, such as feeding upright and avoiding tight diapers.
• Assess for signs of dehydration or electrolyte imbalance in severe cases where vomiting is frequent.

✘Incorrect answer options:

Deficient fluid volume. Frequent vomiting due to GER can lead to fluid loss, putting the infant at risk for dehydration. Monitoring fluid balance is essential, particularly in cases where the infant vomits often.

Risk of aspiration. Aspiration is a significant concern in GER, as stomach contents can reflux into the esophagus and potentially enter the airway. This can lead to respiratory complications such as aspiration pneumonia. Nurses must implement strategies to prevent aspiration, especially when positioning the infant.

Imbalanced nutrition: less than body requirements. Due to regurgitation and vomiting, infants with GER may have difficulty retaining adequate nutrition, which can lead to poor weight gain and delayed growth. Nutritional assessments and feeding interventions are crucial components of nursing care for these infants.

EXPLANATION

✔Correct answer:

Prone with the head to the side. Following cleft palate surgery, positioning the child in a prone position with their head to the side is recommended to allow any oral secretions to drain from the mouth and avoid aspiration. Since children are prone to swallowing blood or saliva after such surgeries, lying on the stomach helps facilitate drainage, which minimizes the risk of choking and prevents respiratory complications. Keeping the child in a prone position also reduces the likelihood of disturbing the surgical site by decreasing the chance that they will accidentally touch their mouth or face, which can be common in supine or semi-Fowler’s positions.

In the early postoperative period, patients may have increased saliva production, minor bleeding, and difficulty swallowing due to swelling and the recent manipulation of tissues in the oral and pharyngeal areas. By positioning the child prone with the head turned to the side, nurses can help ensure that gravity assists in draining saliva and any residual blood out of the mouth, which can prevent aspiration and promote a safe healing environment.

Think of the child’s mouth like a sink that has just been cleaned but still has some water left. If you tilt the sink slightly, the remaining water can drain out naturally. Placing the child in a prone position is like tilting the sink, allowing saliva and secretions to flow out instead of pooling in the back of the throat.

The following actions should be taken to ensure optimal recovery and safety for the child:

• Monitor the child closely for signs of respiratory distress or choking, and be ready to intervene if secretions accumulate.
• Educate the family on the importance of this position and the risks of aspiration if the child is repositioned.
• Ensure the child’s arms are gently restrained to prevent accidental touching or rubbing of the surgical site.
• Provide adequate support for the child’s head and neck to maintain a safe and comfortable position.
• Encourage and facilitate gentle cleaning of oral secretions with soft gauze as needed to maintain cleanliness without disrupting healing.

✘Incorrect answer options:

High Fowler's position. High Fowler's position elevates the head significantly, which may help with drainage in other circumstances, but it does not promote adequate drainage of oral secretions in children following cleft palate surgery. This position also increases the risk of accidental disruption to the surgical site due to the child's tendency to touch their mouth.

Supine with a pillow under the head. The supine position can cause oral secretions to pool in the back of the throat, increasing the risk of aspiration, especially if the child is drowsy or unable to swallow effectively. This position does not adequately address the drainage needs after cleft palate surgery.

Semi-Fowler's position with head slightly elevated. Although the semi-Fowler’s position does provide slight elevation, it is not as effective in allowing oral secretions to drain out of the mouth as the prone position. This elevation is insufficient for preventing the accumulation of saliva and blood, which increases the risk of aspiration.

EXPLANATION

✔Correct answer:

Frequency of vomiting. In infants with gastroesophageal reflux (GER), thickened feedings are commonly used as a management strategy to reduce the frequency and severity of vomiting. The thickened formula or breast milk is intended to stay in the stomach longer and decrease the likelihood of regurgitation by being less prone to backflow through the lower esophageal sphincter. Therefore, the primary parameter Nurse Sarah should monitor to assess the effectiveness of thickened feedings is the frequency of vomiting. If the intervention is effective, there should be a noticeable reduction in vomiting episodes, indicating that the feedings are helping to manage the reflux symptoms.

GER in infants occurs due to an immature or weak lower esophageal sphincter, which allows stomach contents to reflux into the esophagus. By thickening the feedings, the contents are more likely to stay in the stomach, as they are less likely to flow back up. This can help improve feeding tolerance and reduce the distress associated with frequent vomiting episodes.

Think of GER like trying to keep liquid in a tilted bowl with an open edge. A thin liquid would easily spill out, but if you thicken it to more of a pudding-like consistency, it’s more likely to stay in the bowl even if it’s tilted. Thickened feedings help reduce reflux by making the stomach contents harder to spill out.

The following steps can help Nurse Sarah ensure effective monitoring and management for an infant receiving thickened feedings:

• Track and record the frequency, volume, and consistency of vomit after feedings to assess the intervention's effectiveness.
• Educate the parents on signs of improvement, such as reduced vomiting and decreased irritability after feedings.
• Observe for any signs of feeding intolerance, such as gagging, coughing, or increased fussiness, which may indicate the need for further adjustment.
• Monitor for signs of dehydration if vomiting persists despite thickened feedings.

✘Incorrect answer options:

Characteristics of stools. GER typically affects the upper gastrointestinal tract, not the lower. While certain medications or dietary changes can influence stool appearance, monitoring stool characteristics is not directly relevant for evaluating the effectiveness of thickened feedings for GER.

Uterine response. This option is irrelevant, as "uterine response" pertains to pregnancy and labor, not infant GER management.

Changes in weight. While weight gain is an important parameter to monitor in infants with GER, it reflects long-term nutritional status rather than the immediate effectiveness of thickened feedings. A decrease in vomiting would be a more direct and immediate indicator of intervention effectiveness.

EXPLANATION

✔Correct answer:

Ability to suck effectively. A cleft lip can interfere with a newborn’s ability to create the proper seal needed for effective sucking. This can make feeding challenging, as the baby may have difficulty latching onto the breast or bottle and may not be able to generate sufficient suction to extract milk. This feeding difficulty is one of the most common challenges associated with cleft lip (and cleft palate, if present), and it may lead to inadequate nutritional intake if not managed properly.

Think of sucking like drinking through a straw. If the straw has a hole in it (like a cleft), it’s hard to get enough liquid because you can’t create a strong enough vacuum. Similarly, a baby with a cleft lip may struggle to create the suction needed for feeding.

Nurse Amy should focus on interventions that help baby Liam achieve effective feeding despite the cleft lip. Here are some strategies:

• Consider using specialized feeding bottles or nipples designed for babies with cleft lip/palate, which can help compensate for the reduced suction ability.
• Position the baby upright during feedings to reduce the risk of milk entering the nasal cavity and to aid in swallowing.
• Monitor for signs of inadequate nutrition, such as poor weight gain or dehydration, and collaborate with a pediatric dietitian if needed.
• Encourage parents to seek support from a lactation consultant or feeding specialist if they encounter difficulties with feeding.
• Provide guidance on the importance of frequent burping, as babies with cleft lip may swallow more air during feedings.

✘Incorrect answer options:

Breathing patterns. While severe cases of cleft palate (especially cleft palate involving the hard and soft palate) can occasionally impact breathing, a cleft lip alone typically does not affect breathing patterns. Breathing issues are not a primary concern in isolated cleft lip cases.

Ability to move around. A cleft lip does not impact motor function or physical mobility, so there should be no effect on the newborn’s ability to move.

Gastrointestinal function. Gastrointestinal function is not directly affected by a cleft lip. Although feeding difficulties may lead to poor intake and weight gain, the actual gastrointestinal system is not impacted by the cleft lip itself.

EXPLANATION

✔Correct answer:

Displacement. The mother is displaying displacement, a psychological defense mechanism where strong emotions or feelings are redirected from their original source to a less threatening target. In this case, the mother may be feeling anger, frustration, or helplessness due to her child's illness. However, instead of expressing these difficult emotions about the situation, she redirects her anger toward the student nurse, who is a safer target for her frustration. Displacement often occurs when a person feels unable to express their true emotions toward the original source (in this case, her child’s illness or the healthcare situation).

Imagine someone who had a stressful day at work but can't confront their boss. When they come home, they snap at a family member. This is displacement—shifting frustration from the source to a less threatening person or situation.

Understanding that displacement may be at play can help Nurse Alex respond empathetically and de-escalate the situation. Here are some approaches to manage the interaction:

• Remain calm and avoid taking the mother’s words personally, recognizing that her frustration may be due to stress about her child’s illness.
• Acknowledge her emotions with statements like, “I can see that you’re very concerned about your child’s care. Let’s discuss any questions or concerns you have.”
• Provide reassurance by explaining the steps being taken to care for her child, and involve her in the plan of care to help her feel more in control.
• Encourage open communication and offer to connect her with the primary nurse or healthcare provider if she has specific concerns.
• Consider referring the mother to counseling or support services within the hospital if her stress and frustration appear to be overwhelming.

✘Incorrect answer options:

Projection. Projection is a defense mechanism where a person attributes their own unacceptable thoughts or feelings to someone else. For example, if the mother were feeling inadequate about her own ability to care for her child, she might accuse others of being incompetent. However, in this case, she is directly expressing anger at the nurse rather than attributing her own feelings onto someone else.

Repression. Repression involves unconsciously blocking unpleasant or painful emotions, thoughts, or memories from conscious awareness. If the mother were repressing, she would likely not show direct anger. Instead, her feelings would be hidden from her conscious mind, not expressed outwardly.

Psychosis. Psychosis refers to a severe mental disorder in which a person loses touch with reality, often experiencing hallucinations or delusions. The mother’s behavior does not indicate psychosis; she is simply expressing frustration, albeit in an inappropriate way. Her reaction is rooted in stress rather than a loss of reality.

EXPLANATION

✔Correct answer:

Fear of bodily harm or mutilation is a typical fear in preschoolers. Preschool-age children (typically ages 3-5) are in Erik Erikson’s Initiative vs. Guilt stage of psychosocial development. During this period, children begin to assert power and control over their environment through directing play and other social interactions. They are imaginative and curious, but they also tend to have vivid imaginations, which can lead to common fears. A typical fear in preschoolers is the fear of bodily harm or mutilation, as they are developing a sense of self and may be particularly sensitive to changes or perceived threats to their bodies. This fear can manifest as anxiety about medical procedures, shots, or any activity they perceive as potentially causing pain or harm.

Imagine a preschooler thinking of their body as something very special and unique. They might feel anxious about anything that could "break" or hurt it, like a shot, because they can’t yet fully understand that these things are temporary or help them in the long run.

When working with preschool-age children, it’s important for Nurse Liza to consider their developmental fears and take steps to reduce anxiety, especially about bodily harm. Here are some approaches she can use:

• Use simple and reassuring language to explain medical procedures, helping to reduce fear by offering age-appropriate explanations.
• Provide opportunities for the child to ask questions or express their feelings, acknowledging their fears and validating their emotions.
• Allow the child to engage in medical play, such as using a toy medical kit, to help them understand procedures and feel more in control.
• Avoid using phrases that may be frightening, such as “This won’t hurt too much,” as these can reinforce fears of bodily harm.
• Offer comfort measures, such as the presence of a parent or holding a comforting object, to help the child feel secure during medical interventions.

✘Incorrect answer options:

The child is capable of using complex reasoning to solve situations. Preschoolers are still in Piaget’s preoperational stage of cognitive development, where they think concretely and egocentrically. They do not yet have the ability to use complex reasoning or understand abstract concepts. Their thinking is more focused on the here and now, and they often base understanding on appearances and direct experiences.

The child prefers competitive play activities. Competitive play is more typical in school-age children (around 6 years and older) who enjoy structured games with rules and are developmentally ready for competition. Preschoolers generally engage in associative play and cooperative play, where they play alongside or with peers in imaginative and social activities rather than focusing on winning or competing.

Immediate gratification is essential for developing initiative. While preschoolers do appreciate immediate feedback and rewards, developing initiative is more about fostering confidence and independence. It’s about encouraging children to try new activities, make decisions, and assert themselves, rather than focusing on immediate gratification.

EXPLANATION

✔Correct answer:

Contact Protective Services immediately to report the condition. Multiple bruises and burns on an 18-month-old child, particularly on areas like the back, are concerning findings that may indicate possible child abuse. As a mandated reporter, Nurse Carla has a legal and ethical obligation to report any suspicion of abuse to Child Protective Services (CPS) or the appropriate protective agency. In cases where there is reason to suspect abuse, immediate reporting is necessary to ensure the child’s safety and initiate further investigation by the appropriate authorities. Delaying action or relying solely on follow-up visits could put the child at risk of further harm.

Think of a nurse as a "first responder" for signs of child harm. Just as a firefighter would respond quickly to a fire, a nurse must act immediately if they suspect abuse to protect the child and prevent potential harm.

When dealing with suspected abuse, it’s essential for healthcare providers to follow protocols for mandated reporting. Here are some steps Nurse Carla should take:

• Document her observations carefully and objectively, noting the location, size, shape, and color of any bruises or burns.
• Refrain from questioning the child extensively, as this should be handled by trained professionals to avoid leading questions and ensure proper interviewing techniques.
• Contact Child Protective Services or the relevant protective agency immediately to report her findings and provide the necessary details.
• Ensure that any immediate medical needs are addressed, especially if the child appears to be in pain or has untreated injuries.
• Remain supportive and non-judgmental if discussing the case with the family, to avoid escalating the situation or causing distress to the child.

✘Incorrect answer options:

Arrange a follow-up visit to monitor for additional bruises. Waiting to arrange a follow-up visit is inappropriate in cases of suspected abuse. Any delay in reporting could place the child at further risk. Protective services should be notified immediately, and they will determine if follow-up visits are necessary.

Inform the child’s physician immediately about her observations. While informing the physician can be part of the response, it is not sufficient as a primary action. The nurse is required to report suspected abuse directly to protective services, as mandated by law, rather than solely relying on the physician to take further action.

Take no action, as this is a typical finding in toddlers. Multiple bruises and burns on the back of a toddler are not typical findings. While toddlers do often get bruises on their shins, knees, and other bony areas due to falls, bruising and burns on areas like the back are unusual and warrant further investigation for possible abuse.

EXPLANATION

✔Correct answer:

Alert the physician immediately and prepare for intubation. The symptoms described—high fever, inspiratory stridor, restlessness, drooling, and a forward-leaning position—are classic signs of acute epiglottitis. This is a potentially life-threatening condition often caused by bacterial infection (such as Haemophilus influenzae type B, though less common due to vaccination). In cases of epiglottitis, the inflamed epiglottis can obstruct the airway, leading to respiratory distress and possible respiratory failure. The child’s drooling and tripod position (leaning forward) indicate significant respiratory distress and difficulty breathing.

In this scenario, the nurse’s first priority is to ensure the child’s airway remains open. Alerting the physician and preparing for intubation are critical steps. Any attempt to examine the throat with a tongue depressor or perform invasive assessments could further irritate the airway and potentially cause complete airway obstruction. Therefore, immediate medical intervention is necessary to secure the airway and prevent respiratory collapse.

Imagine a clogged drain that’s nearly blocked. If you poke at it, you risk making it worse and causing a complete blockage. Similarly, with epiglottitis, any unnecessary probing can worsen the swelling and block the airway completely, which is why quick intervention by the medical team is essential.

In cases of suspected epiglottitis, immediate action to secure the airway is crucial. Here are some steps the nurse should consider:

• Avoid any invasive assessments of the throat (e.g., using a tongue depressor), as this can trigger complete airway obstruction.
• Notify the physician or emergency team immediately so they can prepare for intubation or other airway management procedures.
• Keep the child calm and avoid causing additional anxiety, which can worsen breathing difficulty.
• Prepare emergency airway equipment, including intubation and tracheostomy supplies, as the child may need rapid intervention.
• Administer supplemental oxygen if tolerated, being careful not to upset the child or force positioning changes.

✘Incorrect answer options:

Listen to his lungs and place him in a mist tent. While listening to lung sounds may provide some information, placing the child in a mist tent is inappropriate for suspected epiglottitis and would delay necessary treatment. The priority is to alert the physician and prepare for potential intubation to secure the airway.

Encourage fluids and have him lie down to rest. Encouraging fluids and having the child lie down could worsen his respiratory distress. Children with epiglottitis often lean forward (tripod position) to help keep their airway open. Lying down could exacerbate airway obstruction.

Check his throat and perform a throat culture. Examining the throat or attempting to take a throat culture could cause further irritation and potentially lead to complete airway obstruction. This should be strictly avoided in cases of suspected epiglottitis. The priority is to secure the airway first.

EXPLANATION

✔Correct answer:

Higher risk for respiratory infections. Children with congenital heart disease (CHD) are at a higher risk for respiratory infections. This is because CHD can lead to poor circulation and fluid buildup in the lungs, creating an environment where bacteria and viruses can more easily take hold. Additionally, the compromised heart function associated with CHD can lead to decreased oxygenation and weaker immune responses, making these children more susceptible to infections, especially in the respiratory tract. Respiratory infections, such as pneumonia or bronchitis, are among the most common complications seen in children with CHD.

Think of the lungs as a sponge that needs to stay mostly dry to prevent mold (infections). In children with heart problems, poor circulation can lead to a buildup of "moisture" (fluid) in the lungs, creating a perfect environment for infections to develop.

When caring for a child with congenital heart disease, it’s essential for Nurse Jenna to focus on preventing and managing respiratory infections. Here are some interventions and considerations:

• Encourage good hand hygiene and infection control practices to minimize exposure to infectious agents.
• Educate family members on the importance of keeping the child away from people with respiratory illnesses, especially during cold and flu season.
• Monitor the child’s respiratory status closely, assessing for any signs of infection, such as increased respiratory rate, cough, or fever, and report changes promptly.
• Ensure that the child is up-to-date on vaccinations, including the flu vaccine and pneumococcal vaccine, to reduce the risk of respiratory infections.
• Provide guidance on recognizing early signs of respiratory distress and when to seek medical attention.

✘Incorrect answer options:

Tendency to experience bleeding. While bleeding disorders can occur with certain heart conditions, they are not a common complication associated with congenital heart disease itself. Unless the child has a coexisting condition (such as a bleeding disorder or is taking anticoagulant therapy), they are not at a higher risk for bleeding.

Frequent episodes of vomiting and diarrhea. Gastrointestinal issues like vomiting and diarrhea are not typically associated with congenital heart disease. If they occur, they may be related to other issues, such as medication side effects, but they are not a primary complication of CHD.

Occurrence of seizure episodes. Seizures are not a common complication of congenital heart disease. While certain severe cases of CHD can lead to hypoxia, which theoretically could increase the risk of neurological issues, seizures are not typically seen as a primary or common complication in children with congenital heart disease.

EXPLANATION

✔Correct answer:

Large blocks. Large blocks are an age-appropriate and developmentally suitable toy for an 8-month-old. At this age, infants are developing their fine motor skills and hand-eye coordination, and large blocks are easy for them to grasp, manipulate, and stack. Playing with blocks encourages exploration and allows the infant to practice grasping, releasing, and even simple stacking, which helps support their cognitive and motor skill development. Large blocks are also safe for infants as they reduce the risk of choking, given their size.

Think of large blocks as "building tools" for the infant’s developing coordination and problem-solving skills. Just as we use tools to practice new skills, infants use blocks to practice grasping and exploring spatial concepts.

When advising parents on appropriate toys for infants, Nurse Emily should consider toys that foster fine motor development, sensory exploration, and safety. Here are some points to include in her guidance:

• Recommend toys that are easy to grasp and manipulate, such as large blocks, which help build hand strength and coordination.
• Emphasize the importance of choosing age-appropriate toys that are large enough to prevent choking, as infants explore by putting objects in their mouths.
• Encourage toys that stimulate sensory exploration, such as toys with different textures or bright colors.
• Explain how play with these types of toys supports cognitive and motor skill development at this stage of infancy.
• Suggest engaging in interactive play with the infant to promote bonding and stimulate the child’s social and emotional development.

✘Incorrect answer options:

Push-pull toys. Push-pull toys are better suited for toddlers who are beginning to walk (usually around 12-18 months). An 8-month-old is typically not developmentally ready for push-pull toys, as they are still developing sitting stability and basic crawling skills.

Rattle. While rattles are appropriate for younger infants (newborn to around 6 months) and can stimulate sensory development, an 8-month-old may benefit more from toys that allow for more complex manipulation and interaction, like large blocks, as they advance in their motor skills.

Mobile. Mobiles are suitable for younger infants (0-5 months) who spend more time lying on their backs and are attracted to visual stimuli. By 8 months, infants are usually more active and need toys that they can reach, grasp, and manipulate directly rather than a mobile, which is primarily visual and intended for younger infants.

EXPLANATION

✔Correct answer:

Contact the physician immediately. In a child with Hirschsprung disease, the combination of fever and sudden explosive, watery diarrhea is highly concerning for Hirschsprung-associated enterocolitis (HAEC), a serious and potentially life-threatening complication. Enterocolitis is an inflammation and infection of the intestines that can lead to rapid deterioration, sepsis, and even death if not treated promptly. Therefore, Nurse Lisa’s priority should be to contact the physician immediately for further evaluation and intervention. Prompt medical attention is critical to initiate supportive care, such as IV fluids, antibiotics, and potentially decompression of the bowel.

Hirschsprung disease is a congenital condition characterized by the absence of ganglion cells in the distal colon, resulting in a lack of peristalsis in the affected segment. This leads to intestinal obstruction and accumulation of fecal material. Enterocolitis may develop due to bacterial overgrowth and stasis in the colon, causing symptoms like fever, diarrhea, and abdominal distension. HAEC can progress quickly to sepsis, so rapid intervention is essential.

Think of the intestine like a pipe that should have a smooth inner lining to allow things to flow through. In Hirschsprung disease, part of the pipe lacks the ability to push things along, causing blockages. When this blockage becomes infected and starts to overflow, it’s like a dangerous leak that needs immediate repair to prevent further damage.

Given the risk of rapid deterioration with HAEC, Nurse Lisa should focus on ensuring timely intervention and monitoring the child’s vital signs and hydration status.

• Immediately notify the physician of the symptoms (fever and explosive diarrhea), as they may indicate a life-threatening condition.
• Monitor vital signs frequently to detect any signs of worsening condition, such as increased heart rate, hypotension, or respiratory distress.
• Assess the child’s hydration status and be prepared to initiate IV fluids if prescribed, as diarrhea can lead to dehydration.
• Avoid giving any medications or interventions without physician orders, as antidiarrheal medications are contraindicated in this situation due to the risk of worsening the obstruction.
• Prepare to support the family and provide education about the seriousness of enterocolitis in Hirschsprung disease, including the importance of prompt medical intervention.

✘Incorrect answer options:

Give antidiarrheal medication. Antidiarrheal medications are contraindicated in children with Hirschsprung disease, especially if enterocolitis is suspected. These medications can worsen the obstruction and increase the risk of toxic megacolon, a potentially fatal complication.

Check on the child every 30 minutes. While close monitoring is important, this response is insufficient given the severity of the symptoms. Immediate action is needed, not just periodic checks.

Take no action, as this is typical of Hirschsprung disease. Sudden explosive diarrhea and fever are not typical of Hirschsprung disease; these symptoms suggest enterocolitis, which is a medical emergency. Taking no action would be inappropriate and could lead to serious complications.

EXPLANATION

✔Correct answer:

Around 12 months. A child’s birth weight is typically expected to triple by the time they reach 12 months (1 year) of age. This milestone is a common benchmark in pediatric growth and development assessments. In the first year, infants experience rapid growth, with most doubling their birth weight by around 4-6 months and tripling it by around 12 months. This rate of weight gain then slows down after the first year.

Think of an infant’s weight gain as a three-step process in the first year: doubling by the halfway mark (around 4-6 months) and tripling by the end of the first year. It’s like reaching checkpoints in a race—first to double, then to triple by 12 months.

During well-child checkups, it’s essential for nurses to monitor growth patterns and ensure they fall within expected ranges. Here are some approaches Nurse Sarah can use:

• Use growth charts to track the child’s weight gain, length, and head circumference to assess overall growth trends.
• Educate parents about normal growth expectations and reassure them about healthy weight gain patterns, highlighting that growth slows down after the first year.
• Assess nutritional intake to ensure the child is receiving adequate calories, whether through breastfeeding, formula, or the introduction of solids, to support healthy growth.
• Screen for any signs of failure to thrive if growth benchmarks are not being met, and consider further evaluation if growth is consistently below expected patterns.
• Encourage regular follow-up appointments to monitor growth milestones and detect any potential issues early.

✘Incorrect answer options:

Around 4 months. By 4 months, most infants are expected to have gained weight rapidly but generally have not doubled their birth weight yet, let alone tripled it.

Around 7 months. By 7 months, infants typically double their birth weight but do not reach the benchmark of tripling until about 12 months.

Around 9 months. Although growth continues steadily at 9 months, infants generally do not triple their birth weight until closer to 12 months.

EXPLANATION

✔Correct answer:

Wheat. In celiac disease, the immune system reacts to gluten, a protein found in wheat, barley, and rye. This reaction damages the small intestine's lining, leading to malabsorption of nutrients and a range of gastrointestinal symptoms, including abdominal pain, diarrhea, and bloating. To manage celiac disease, it is crucial to avoid all foods containing gluten, with wheat being one of the primary sources. Even small amounts of gluten can trigger symptoms and intestinal damage, so Nurse Laura should emphasize the need for Sam and his family to carefully avoid wheat and check food labels for hidden gluten sources.

Celiac disease is an autoimmune disorder where ingestion of gluten causes an immune response that damages the villi in the small intestine. These villi are essential for nutrient absorption, so when they are damaged, it leads to malnutrition, anemia, and other long-term complications if gluten is not strictly avoided. By eliminating gluten from the diet, the intestinal lining can heal, and symptoms are usually managed effectively.

Imagine the small intestine as a sponge that soaks up nutrients. In celiac disease, eating gluten is like pouring a harmful substance over the sponge, damaging it so it can’t absorb properly. Removing gluten is like taking away the harmful substance, allowing the sponge to return to its normal function over time.

The following instructions should be emphasized for Sam and his family to ensure effective management of celiac disease:

• Educate the family on reading food labels to identify hidden sources of gluten, as wheat and gluten are often present in processed foods.
• Provide a list of safe, gluten-free grains such as rice, corn, quinoa, and certified gluten-free oats.
• Encourage a balanced diet with naturally gluten-free foods like fruits, vegetables, meats, dairy, and rice to ensure adequate nutrition.
• Advise against cross-contamination in the kitchen, such as by using separate utensils, cookware, and toasters for gluten-free foods.
• Encourage family involvement and support to help Sam adhere to the dietary restrictions both at home and in social settings.

✘Incorrect answer options:

Rice. Rice is a gluten-free grain and is safe for individuals with celiac disease. It is often recommended as an alternative to gluten-containing grains.

Milk. Milk does not contain gluten and is safe for those with celiac disease. However, lactose intolerance can sometimes occur secondary to celiac disease due to damage in the small intestine, but milk itself does not need to be avoided unless symptoms are present.

Chicken. Chicken is naturally gluten-free and safe for individuals with celiac disease. As long as it is not breaded or prepared with gluten-containing ingredients, it does not pose a risk.

EXPLANATION

✔Correct answer:

At 12 months. The varicella zoster vaccine, which protects against chickenpox, is typically administered at 12 months of age as the first dose. According to the CDC’s immunization schedule, the first dose of the varicella vaccine is given at 12-15 months, with a second dose recommended at 4-6 years. Administering the vaccine at 12 months ensures that the child has developed sufficient immune system maturity to respond effectively to the vaccine and build immunity against the varicella virus.

Think of a young child’s immune system as a “team” that is still in training. By 12 months, this team has developed enough strength to handle the varicella vaccine and learn how to defend against the virus.

When educating parents about the varicella vaccine, Nurse Leah should provide information about the vaccination schedule and address any questions or concerns. Here are some points to consider:

• Inform parents that the varicella vaccine is given as a two-dose series, with the first dose at 12-15 months and the second dose at 4-6 years.
• Explain the importance of the vaccine in preventing chickenpox, a highly contagious disease that can lead to serious complications, especially in young children and immunocompromised individuals.
• Discuss possible mild side effects of the vaccine, such as soreness at the injection site or a mild rash, and reassure parents that these are generally short-lived.
• Encourage parents to keep an updated vaccination record and schedule timely visits to ensure their child stays on track with recommended immunizations.
• Address any questions about vaccine safety and effectiveness, as some parents may have concerns about vaccines. Provide evidence-based information to support informed decision-making.

✘Incorrect answer options:

At birth. The varicella vaccine is not administered at birth. Newborns receive vaccines for hepatitis B at birth, but the varicella vaccine is delayed until 12 months due to the immaturity of the immune system in infancy.

At 2 months. At 2 months, infants typically receive vaccines for hepatitis B (second dose), DTaP (diphtheria, tetanus, pertussis), Hib (Haemophilus influenzae type b), IPV (polio), pneumococcal, and rotavirus. The varicella vaccine is not included in the 2-month immunization schedule.

At 6 months. At 6 months, infants receive additional doses of vaccines such as DTaP, IPV, hepatitis B (if following a 3-dose schedule), and influenza (if in season). The varicella vaccine is still not given at this age; it is recommended to be administered starting at 12 months.

EXPLANATION

✔Correct answer:

Reviewing the family history. Reviewing the family history would be the least helpful assessment when evaluating a toddler with suspected intussusception. Intussusception is a condition in which a part of the intestine telescopes into itself, causing an obstruction. This can lead to symptoms such as abdominal pain, "currant jelly" stools (which are stools mixed with blood and mucus), and a palpable mass in the abdomen. While family history can be relevant for many conditions, intussusception is typically not associated with a hereditary pattern. Instead, it is usually an isolated event that can occur due to various factors, including viral infections or anatomical differences, but it does not have a strong genetic component.

Checking the stool characteristics, observing the pain pattern, and performing abdominal palpation are all essential assessments in identifying intussusception. These can provide direct clues about the presence of this condition:

• Stool Characteristics: A classic sign of intussusception is "currant jelly" stools, which contain blood and mucus. Identifying this stool pattern is highly indicative of intussusception.
• Pattern of Pain: Children with intussusception often experience intermittent, severe abdominal pain that causes them to draw their legs up toward their abdomen and cry out. These episodes may alternate with periods of calm, which is a key characteristic of this condition.
• Abdominal Palpation: Palpating the abdomen may reveal a "sausage-shaped" mass, typically located in the right upper quadrant, which can help confirm the diagnosis.

Think of intussusception as a telescope that’s been collapsed into itself. Just as the collapsed telescope forms a dense segment, the telescoping intestine forms a palpable mass in the abdomen. Checking the family history wouldn’t help identify this collapsed section, but examining the abdomen and stool characteristics would.

Nurse Dana should focus on assessments that can provide immediate diagnostic clues and support early intervention for intussusception.

• Monitor the child’s stool for "currant jelly" appearance and document any findings, as this is a hallmark symptom of intussusception.
• Observe for signs of pain, noting if it occurs in episodes, as this pattern is characteristic of intussusception.
• Perform gentle abdominal palpation to assess for a mass, which can help in identifying the condition, but avoid excessive pressure due to the risk of worsening the obstruction.
• Prepare the child and family for possible imaging studies, such as an ultrasound, which can confirm the diagnosis.
• Educate the family about intussusception and the importance of prompt treatment, as untreated intussusception can lead to bowel necrosis and other severe complications.

✘Incorrect answer options:

Checking the stool characteristics. Checking for "currant jelly" stools is very important, as this is a common and specific sign of intussusception. Blood and mucus in the stool indicate bowel involvement and help confirm the diagnosis.

Observing the pattern of pain. The intermittent nature of abdominal pain is a key characteristic of intussusception. This "colicky" pain pattern, with sudden onset and episodes of severe pain, is valuable for diagnosing this condition.

Performing abdominal palpation. Palpating the abdomen for a "sausage-shaped" mass, often in the right upper quadrant, is a useful physical assessment for intussusception. This mass represents the telescoped section of the bowel and can aid in diagnosis.

EXPLANATION

✔Correct answer:

Slow to learn self-feeding skills. In children with mild intellectual disability (formerly referred to as "mild mental retardation"), delays in adaptive skills, such as self-feeding, dressing, and toileting, are commonly observed. These children may reach developmental milestones at a slower pace compared to their peers but are generally able to learn basic self-care skills with appropriate guidance and support. For example, a preschooler with mild intellectual disability may take longer to master self-feeding skills, such as using utensils independently, due to slower cognitive processing and motor planning.

Think of self-feeding as learning to ride a bike. A child with mild intellectual disability may take more time to balance and coordinate the actions, but with practice, they can achieve it, even if at a slower pace than peers.

When working with preschoolers who have mild intellectual disabilities, Nurse Amy should focus on supporting their developmental skills in a way that fosters independence. Here are some strategies:

• Encourage caregivers to use simple instructions and repeat tasks to help reinforce learning and skill development.
• Provide positive reinforcement and celebrate small successes to build the child's confidence in self-care activities.
• Advise parents on using adaptive tools, like utensils with larger handles, to make self-feeding easier and more manageable.
• Support the child’s participation in daily routines, as repetition helps reinforce adaptive skills.
• Coordinate with occupational therapists if additional support is needed to help the child develop fine motor skills for self-feeding and other self-care tasks.

✘Incorrect answer options:

Absence of speech development. Children with mild intellectual disability usually exhibit delayed speech development, but not a complete absence of speech. They may struggle with complex language but can typically learn to communicate with simple words and sentences, albeit at a slower pace.

Significant motor skill delays. Significant motor delays are more characteristic of children with moderate to severe intellectual disability. Children with mild intellectual disability may have some fine motor delays but are generally able to perform gross motor tasks, such as running and climbing, with only minor delays.

Difficulty with walking (gait disability). Gait disabilities are not typically associated with mild intellectual disability. While children with more severe forms of intellectual disability may experience motor difficulties, children with mild intellectual disability are usually able to walk and have no major gait abnormalities.

EXPLANATION

✔Correct answer:

Forceful projectile vomiting. Pyloric stenosis is a condition in infants where the pylorus, the muscular opening from the stomach to the small intestine, becomes abnormally thickened. This thickening obstructs the passage of food, causing symptoms related to impaired gastric emptying. One of the hallmark signs of pyloric stenosis is forceful projectile vomiting. This vomiting typically occurs shortly after feeding, as the stomach's contents cannot pass through the narrowed pylorus, resulting in strong, projectile ejection of the milk or formula. The vomit is usually non-bilious, meaning it does not contain bile, because it has not reached the intestines.

In pyloric stenosis, the pyloric muscle hypertrophies (becomes enlarged), which restricts the gastric outlet and prevents food from moving into the duodenum. This causes increased gastric pressure that ultimately leads to the forceful expulsion of stomach contents through the mouth. As a result, infants with pyloric stenosis often experience dehydration, weight loss, and may appear increasingly hungry after vomiting episodes because the food was not absorbed.

Imagine trying to squeeze toothpaste through a tube with a very narrow opening. If you apply enough pressure, the toothpaste will shoot out forcefully. Similarly, in pyloric stenosis, milk builds up in the stomach until it’s ejected forcefully because it can't pass through the narrow pyloric opening.

The following actions should be taken when caring for an infant with suspected pyloric stenosis:

• Observe and document vomiting episodes, noting frequency, amount, and characteristics of the vomit (e.g., projectile and non-bilious).
• Monitor the infant’s hydration status by assessing skin turgor, fontanelles, urine output, and mucous membranes.
• Assess for signs of electrolyte imbalance due to frequent vomiting, including lethargy and irritability.
• Provide education to the family about the condition and the importance of prompt surgical intervention (pyloromyotomy).
• Prepare the infant and family for possible surgical correction, which is the definitive treatment for pyloric stenosis.

✘Incorrect answer options:

Frequent regurgitation. While infants with pyloric stenosis may experience regurgitation, it is the forceful, projectile nature of vomiting that is characteristic of this condition. Regurgitation is more common in infants with gastroesophageal reflux (GER), which is less severe and lacks the forceful expulsion seen in pyloric stenosis.

Presence of fatty stools (steatorrhea). Fatty stools (steatorrhea) are not associated with pyloric stenosis. Steatorrhea is typically seen in conditions that affect fat absorption, such as cystic fibrosis or certain malabsorption syndromes, not in gastric outlet obstruction.

Stools that resemble "currant jelly." Currant jelly stools are a classic symptom of intussusception, a different pediatric gastrointestinal condition in which a portion of the intestine telescopes into an adjacent section. This leads to bleeding and mucus in the stool, giving it a characteristic appearance. This symptom is not related to pyloric stenosis.

EXPLANATION

✔Correct answer:

Contact the physician immediately. The symptoms described—intense, unrelenting pain, pallor of the foot, and a full leg cast—are classic signs of compartment syndrome, a medical emergency that requires prompt intervention to prevent permanent damage. Compartment syndrome occurs when pressure builds up within a closed muscle compartment, leading to decreased blood flow and potential tissue death. If untreated, it can result in irreversible damage to nerves and muscles, and in severe cases, may require amputation. Contacting the physician immediately is the priority so that the cast can be removed or other surgical interventions (such as a fasciotomy) can be performed to relieve the pressure.

Think of compartment syndrome like a balloon being over-inflated inside a small box. The pressure inside the box builds up rapidly, and if it’s not released quickly, the balloon (tissue) could burst or be permanently damaged. Contacting the physician is the only way to relieve the pressure in time to save the tissue.

When assessing a patient with a cast, it’s essential for the nurse to recognize the signs of compartment syndrome and act quickly. Here are some steps Nurse Kim should consider:

• Contact the physician immediately to report the findings, as compartment syndrome requires urgent intervention.
• Elevate the affected limb to the level of the heart (not above), which helps avoid further reduction in blood flow.
• Monitor and document neurovascular status closely, assessing for the "6 Ps" of compartment syndrome: Pain, Pallor, Pulselessness, Paresthesia, Paralysis, and Poikilothermia (coolness).
• Avoid applying ice to the affected area, as this may worsen vasoconstriction and reduce blood flow.
• Provide reassurance to the patient and educate them on the importance of reporting any worsening symptoms, especially pain that is unrelieved by medication.

✘Incorrect answer options:

Administer acetaminophen for pain relief. Pain associated with compartment syndrome is usually intense and unrelieved by standard pain medications. Administering acetaminophen will not address the underlying cause (pressure within the compartment) and could delay necessary intervention if the nurse does not act promptly to contact the physician.

Release the traction on his leg. While releasing traction might be appropriate in certain situations, there is no indication here that the patient is in traction. The focus should be on contacting the physician to assess for compartment syndrome and remove or split the cast if necessary.

Monitor his condition every 5 minutes. Monitoring alone is not an adequate response for suspected compartment syndrome. Prompt action to involve the physician is essential to relieve the pressure as soon as possible. Delaying intervention could lead to permanent damage.

EXPLANATION

✔Correct answer:

Implementing infection control measures. For a child with acute lymphocytic leukemia (ALL), the primary concern is their increased susceptibility to infections. ALL affects the bone marrow, leading to decreased production of healthy white blood cells, which compromises the immune system. Chemotherapy, a standard treatment for leukemia, further suppresses immunity, increasing the risk of infections. Implementing strict infection control measures—such as hand hygiene, limiting exposure to infectious agents, and possibly placing the child in protective isolation—is essential to protect the child from potentially life-threatening infections. Preventing infections is a critical component of the care plan for children with ALL and should be Nurse Linda’s initial priority.

Think of a child with leukemia like someone who has a very fragile "shield" (immune system). If the shield is weak, they’re more vulnerable to "arrows" (germs and infections). So, the first priority is to prevent those arrows from hitting by keeping germs away, which is done through infection control.

When caring for a child with ALL, Nurse Linda should focus on infection prevention as a top priority. Here are some specific strategies:

• Practice and educate caregivers on rigorous hand hygiene, as this is one of the most effective methods to prevent the spread of infection.
• Limit visitors and encourage the use of masks for anyone entering the child's room to reduce exposure to infectious agents.
• Monitor for early signs of infection, such as fever, and report any abnormal findings promptly, as timely intervention is crucial.
• Consider placing the child in a protective or reverse isolation setting if required, to minimize contact with potentially infectious individuals.
• Educate the family on signs of infection and the importance of keeping the child away from crowded or germ-prone environments during immunosuppressive therapy.

✘Incorrect answer options:

Promoting the intake of iron-rich foods. While nutritional support is important, iron intake is not a primary concern for a child with ALL. Children with leukemia often have compromised bone marrow function, which impacts blood cell production, but the focus is not typically on iron supplementation. Infection control is a much higher priority initially.

Supporting the child in coping with chronic illness. Providing psychological support is important in managing a chronic illness like leukemia, as children may experience fear, anxiety, and changes in self-concept. However, coping strategies would be addressed after immediate physical needs—such as infection prevention—are managed.

Administering medications through intramuscular injections. Intramuscular injections are generally avoided in children with ALL due to the risk of bleeding, as leukemia can cause low platelet counts and impaired clotting. Medications are usually administered intravenously or orally. Infection control remains the primary priority over medication route decisions.

EXPLANATION

✔Correct answer:

Hirschsprung disease. Failure to pass meconium within the first 24 to 48 hours after birth is a classic sign of Hirschsprung disease, a congenital disorder in which nerve cells (ganglion cells) are absent in a portion of the large intestine. This absence of ganglion cells prevents normal peristalsis in the affected section of the bowel, causing a blockage that prevents stool from passing through. As a result, newborns with Hirschsprung disease may have a delay or complete absence of meconium passage. If left untreated, this can lead to severe complications, including enterocolitis and bowel obstruction.

Hirschsprung disease occurs when ganglion cells do not develop in segments of the colon during fetal development. These cells are essential for coordinating muscle contractions in the bowel, allowing for the smooth movement of stool. Without them, the affected section of the colon becomes a functional obstruction, causing an inability to pass stool, abdominal distension, and eventual vomiting if left untreated.

Imagine a train track that has a broken segment. When the train reaches the broken section, it can’t pass through, causing a backup on the track. In Hirschsprung disease, the lack of nerve cells is like the broken track, preventing stool from moving forward, causing a blockage.

Nurse Emily should be aware of the signs of Hirschsprung disease and prepare for further diagnostic evaluation and potential interventions if the condition is confirmed.

• Monitor for additional signs of bowel obstruction, including abdominal distension, vomiting, and feeding intolerance.
• Inform the pediatric team of the delayed passage of meconium to initiate early diagnostic testing, such as a rectal biopsy or contrast enema.
• Educate the parents on potential symptoms and the importance of prompt treatment to avoid complications.
• Prepare for possible surgical intervention (resection of the affected bowel segment), which is the standard treatment for Hirschsprung disease.
• Provide emotional support to the family, as a diagnosis of Hirschsprung disease may lead to concerns about future bowel function and nutrition.

✘Incorrect answer options:

Celiac disease. Celiac disease is an autoimmune condition triggered by gluten ingestion, leading to intestinal inflammation and malabsorption. However, it typically manifests later in life after gluten-containing foods are introduced. It is not associated with delayed meconium passage in newborns.

Intussusception. Intussusception is a condition where a part of the intestine telescopes into itself, causing obstruction. While it can lead to symptoms like abdominal pain and "currant jelly" stools in older infants, it is not associated with delayed meconium passage in the neonatal period.

Abdominal wall defect. Abdominal wall defects, such as gastroschisis or omphalocele, are structural anomalies where abdominal contents protrude outside the body. While they are congenital conditions, they are typically visible at birth and do not directly cause delayed passage of meconium.
