Maternal & Child Practice Exam 10

EXPLANATION

✔Correct answer:

Placenta. The placenta is not considered part of the "passageway" in labor and delivery. The passageway specifically refers to the maternal anatomical structures that the fetus must travel through during childbirth, including the pelvis, cervix, and vagina. These structures form the birth canal that facilitates the fetus's descent and eventual delivery.

The placenta, on the other hand, is an organ that provides oxygen and nutrients to the fetus during pregnancy and removes waste products. While it plays a crucial role in fetal development, it does not participate in the actual passage of the fetus through the birth canal. After the baby is delivered, the placenta is typically expelled in a process called the "third stage of labor."

Think of the passageway as a tunnel the baby must pass through to be born, made up of specific parts like the pelvis, cervix, and vagina. The placenta, however, is like a supportive system inside the uterus—it provides nutrition and oxygen but isn't part of the tunnel itself.

Nurses play a key role in assessing and supporting the function of the passageway during labor. Here are some key considerations related to the components of the passageway:

• Monitor cervical dilation and effacement as they indicate how prepared the passageway is for the fetus's descent.
• Assess pelvic adequacy through prenatal evaluations, as certain pelvic shapes may impact delivery and lead to complications.
• Encourage positioning techniques, such as squatting or side-lying, to help maximize pelvic opening and support the descent of the fetus.
• Support the patient with breathing and relaxation techniques to aid the stretchability of the vaginal tissues during delivery.
• Provide information about the role of the placenta in pregnancy and reassure the patient that its delivery will follow shortly after the baby.

✘Incorrect answer options:

Pelvis. The pelvis forms the bony structure of the passageway and is crucial for labor. The shape, size, and flexibility of the pelvic bones affect the fetus’s ability to descend through the birth canal. Certain pelvic types are more favorable for vaginal delivery, making the pelvis an essential part of the passageway.

Cervix. The cervix is a critical part of the passageway. During labor, it dilates (opens) and effaces (thins out) to allow the fetus to move from the uterus into the vaginal canal. These changes in the cervix are essential for labor progression and fetal descent.

Vagina. The vagina and its opening are integral parts of the passageway. This canal serves as the final part of the birth canal through which the fetus exits the mother’s body. The stretchability of the vaginal tissues is important for the fetus’s passage during delivery.

EXPLANATION

✔Correct answer:

Left occiput anterior (LOA). The left occiput anterior (LOA) position describes the fetal position when the back of the fetal head (occiput) is facing toward the mother's left anterior (front) quadrant. In this position, the posterior fontanel (a small triangular soft spot on the back of the fetal head) would be felt in the left upper quadrant of the mother’s pelvis during a vaginal examination.

To determine fetal position, you focus on the orientation of the occiput (the back of the baby's head) relative to the mother's pelvis. In the LOA position:

• Left (L) indicates that the occiput is pointing toward the mother’s left side.
• Occiput (O) indicates that the landmark being used is the occiput, the back of the baby’s head.
• Anterior (A) indicates that the occiput is facing toward the mother’s anterior, or front.

LOA is one of the most favorable positions for delivery, as it allows for an optimal alignment of the fetal head with the birth canal, facilitating a smoother descent and delivery.

Think of the baby’s head as a compass. The posterior fontanel (back of the head) points to the "direction" the baby is facing in the pelvis. If the posterior fontanel is on the mother’s left front side, it tells us that the baby is in the LOA position, facing the mother's right side with the occiput pointing toward her left front.

Understanding fetal positioning is essential for assessing labor progress and identifying potential issues.

• Document the fetal position as LOA, as this is helpful information for both the nursing and medical team.
• Encourage positions and movements that support optimal alignment of the baby’s head with the pelvis if labor needs to progress further.
• Monitor for signs of effective labor progress, as LOA is generally a favorable position for vaginal delivery.
• Educate the mother on the baby’s position to help her understand how labor is progressing and reassure her about the favorable position.

✘Incorrect answer options:

Right occiput anterior (ROA). In the ROA position, the posterior fontanel would be felt in the mother’s right upper quadrant. This would indicate the occiput is pointing toward the mother's right side, not her left.

Left occiput posterior (LOP). In the LOP position, the occiput would be facing the mother’s left posterior (back) quadrant. The posterior fontanel would be felt in the left lower quadrant, rather than the upper quadrant, indicating the fetal head is turned more toward the mother’s back.

Right occiput posterior (ROP). In the ROP position, the occiput would be facing the mother’s right posterior (back) quadrant, and the posterior fontanel would be found in the right lower quadrant. This is the opposite side and orientation of the LOA position.

EXPLANATION

✔Correct answer:

There is a fluid shift from the placental circulation to the mother’s circulation, which can strain her already compromised heart. The first 2 hours after delivery is a critical period for a postpartum patient with a cardiac condition due to a significant fluid shift that occurs as blood that was previously directed to the placenta is redirected back into the mother’s circulation. This sudden increase in blood volume can place considerable strain on the mother's heart, especially if it is already compromised by a pre-existing cardiac condition.

During pregnancy, the maternal circulatory system adapts to accommodate increased blood volume and placental circulation. After delivery, as the uterus contracts and the placenta is removed, the extra blood volume from the placenta rapidly returns to the maternal circulation. This can lead to fluid overload and exacerbate conditions like heart failure or arrhythmias in mothers with weakened or compromised cardiac function.

Imagine a water tank that suddenly receives an extra influx of water from a secondary tank being emptied into it. If the main tank is already weak or damaged, this sudden increase in volume can cause strain, increasing the risk of overflow or rupture. Similarly, the mother’s heart must handle a sudden return of blood volume after delivery, putting extra stress on an already weakened cardiac system.

Nurses should monitor postpartum patients with cardiac conditions closely, especially in the first 2 hours after delivery.

• Monitor vital signs, including heart rate, respiratory rate, and blood pressure, to detect signs of fluid overload or heart failure.
• Assess for symptoms of cardiac decompensation, such as dyspnea, chest pain, palpitations, and peripheral edema.
• Limit physical activity and provide a calm environment to reduce cardiac workload during this critical period.
• Collaborate with the healthcare team to ensure appropriate medications are administered to manage fluid balance and reduce strain on the heart if necessary.
• Educate the mother and family about the importance of monitoring cardiac symptoms and reporting any signs of distress immediately.

✘Incorrect answer options:

The mother’s heart is severely weakened, increasing the risk of mortality. While certain cardiac conditions may weaken the mother’s heart, this is not what makes the first 2 hours postpartum particularly risky. The key issue is the rapid fluid shift into maternal circulation that stresses the heart, not the inherent weakness of the heart itself.

The delivery was physically taxing on the mother. While delivery can be physically demanding, the primary concern in the immediate postpartum period is the physiological fluid shift, which affects mothers with cardiac conditions more than the physical exertion of delivery itself.

The mother’s fatigue and weakness may place stress on her heart. Although fatigue can contribute to overall stress on the body, the specific risk during the first 2 hours postpartum is due to the rapid return of blood volume to maternal circulation, not simply fatigue or weakness.

EXPLANATION

✔Correct answer:

Ritgen’s maneuver. Ritgen’s maneuver is not classified as a natural childbirth method. It is a technique used by healthcare providers during the actual delivery of the baby’s head to help control its descent and reduce perineal tearing. In Ritgen’s maneuver, the provider applies pressure to the perineum and the baby's head, assisting in a controlled delivery. This is a hands-on technique used by the medical team and does not involve the expectant mother’s personal efforts in coping with labor or promoting a natural childbirth experience.

In contrast, the Lamaze method, Dick-Read method, and psychoprophylactic method are all natural childbirth techniques that focus on empowering the mother to manage pain and stress during labor without the use of medical interventions. These methods incorporate breathing exercises, relaxation techniques, and education to help the mother achieve a more comfortable and positive childbirth experience.

Think of Ritgen’s maneuver as a technique the "coach" (the healthcare provider) uses to help control the final moments of a race. In contrast, natural childbirth methods like Lamaze or Dick-Read are techniques the "runner" (the expectant mother) uses to pace herself and manage her energy throughout the race.

Nurses educating expectant mothers on natural childbirth methods should focus on techniques that help mothers cope with labor in a way that aligns with their personal goals for childbirth.

• Educate expectant mothers on various natural childbirth methods, such as Lamaze and Dick-Read, to promote relaxation and pain management without medical intervention.
• Provide guidance on breathing exercises and relaxation techniques that are core components of natural childbirth methods.
• Clarify the role of the healthcare provider in performing maneuvers like Ritgen’s to ensure safe delivery but differentiate it from self-managed methods.
• Encourage questions and discussions about the benefits and limitations of natural childbirth techniques to help mothers make informed choices.
• Offer resources or classes that can provide additional support for mothers interested in practicing natural childbirth techniques.

✘Incorrect answer options:

Lamaze method. The Lamaze method is a popular natural childbirth technique that focuses on breathing exercises, relaxation, and positive visualization to help the mother cope with labor pain naturally.

Dick-Read method. The Dick-Read method, also known as the Fear-Tension-Pain method, promotes a natural childbirth experience by reducing fear and tension through education and relaxation, aiming to alleviate pain.

Psychoprophylactic method. The psychoprophylactic method is another natural childbirth approach that uses psychological preparation, relaxation, and breathing techniques to help the mother manage labor pain and reduce anxiety.

EXPLANATION

✔Correct answer:

Incomplete. Incomplete is not a specific type of breech presentation. The term “incomplete” does not refer to a distinct breech presentation, although it may be used informally to describe certain variations. The three main types of breech presentations are footling, frank, and complete.

1. Footling Breech: In this presentation, one or both feet are positioned to come out first. This is the least common and is considered a higher-risk breech because the feet can enter the birth canal first, which may lead to complications.
2. Frank Breech: In a frank breech, the baby’s legs are extended straight up toward the head, with the buttocks positioned to come out first. This is the most common type of breech presentation.
3. Complete Breech: In a complete breech, the baby’s hips and knees are both flexed, so the baby sits cross-legged, with the buttocks aimed to come out first.

The term "incomplete" does not refer to a specific breech position. It may be used to describe any variation that does not fit neatly into the classifications above, but it is not recognized as a standalone type.

Think of breech presentations as seating positions: in the "footling" position, the baby’s foot sticks out like a leg hanging off a chair; in the "frank" position, the legs are straight up; in the "complete" position, the baby sits cross-legged. "Incomplete" is not a specific seating position but might imply a mix that doesn't fully fit any standard position.

Nurses should be familiar with the types of breech presentations to identify potential risks and discuss birth options with patients and the healthcare team.

• Recognize and document the type of breech presentation accurately if identified during a physical exam or ultrasound.
• Educate expectant mothers on breech presentations, including the risks and possible delivery methods, such as cesarean section for certain breech types.
• Prepare for a potential cesarean delivery if the breech presentation is not resolved before labor begins, as some breech positions pose risks for vaginal birth.
• Monitor fetal well-being closely in cases of breech presentation, as some types may increase the risk of umbilical cord compression.
• Encourage discussion with the healthcare provider about options like external cephalic version (ECV) to attempt to turn the baby if appropriate.

✘Incorrect answer options:

Footling. A footling breech is a recognized type of breech presentation where one or both of the baby’s feet are positioned to come out first. This position can increase delivery risks and often requires a cesarean section.

Frank. A frank breech is the most common breech position, where the baby’s legs are extended up toward the head, with the buttocks positioned to come out first.

Complete. In a complete breech, the baby’s hips and knees are both flexed, allowing the baby to sit cross-legged with the buttocks presenting first.

EXPLANATION

✔Correct answer:

Pitocin. Pitocin (synthetic oxytocin) is the drug commonly administered parenterally (typically via IV or IM injection) to strengthen uterine contractions in postpartum patients. Pitocin is frequently used to help the uterus contract firmly after childbirth, which is essential to reduce the risk of postpartum hemorrhage by compressing the blood vessels at the site where the placenta was attached. By promoting strong and sustained uterine contractions, Pitocin helps prevent excessive bleeding, which is a critical component of postpartum care.

Pitocin is often administered immediately after delivery, especially in cases where there is an increased risk of uterine atony (lack of uterine tone) or hemorrhage. It can also be used during labor to induce or augment contractions, but in the postpartum period, its primary purpose is to ensure effective uterine involution.

Think of Pitocin as the “reminder” signal for the uterus to tighten up and stay firm after the baby is born, similar to tightening a drawstring bag to keep everything secure and prevent anything from spilling out.

Nurses should be aware of the effects and monitoring requirements when administering Pitocin to postpartum patients.

• Administer Pitocin as per the physician’s order, usually via IV or IM route, and monitor the patient closely for signs of effective uterine contraction.
• Assess the uterus for firmness and monitor for signs of postpartum bleeding, which should decrease as the uterus contracts.
• Monitor the patient’s vital signs, as Pitocin can occasionally cause side effects such as increased blood pressure.
• Educate the patient about the purpose of Pitocin in preventing postpartum hemorrhage and ensure they are aware of any potential side effects.
• Document the administration of Pitocin, including the dose, route, and the patient’s response to the medication.

✘Incorrect answer options:

Terbutaline. Terbutaline is a tocolytic medication, meaning it is used to relax uterine contractions rather than strengthen them. It is often used to delay preterm labor by reducing uterine activity, making it unsuitable for use in the postpartum period to strengthen contractions.

Magnesium sulfate. Magnesium sulfate is also a tocolytic agent and is primarily used to prevent seizures in patients with preeclampsia or to relax uterine contractions in cases of preterm labor. It is not used to promote or strengthen uterine contractions.

Lidocaine. Lidocaine is a local anesthetic used to numb tissue in a specific area. It has no effect on uterine contractions and is typically used for procedures requiring local anesthesia, such as episiotomy repairs, not for postpartum uterine contraction.

EXPLANATION

✔Correct answer:

Oxytocin could cause the cervix to close, potentially trapping the placenta inside. Administering oxytocin before the placenta is delivered could stimulate strong uterine contractions that may cause the cervix to close prematurely. This could potentially "trap" the placenta inside the uterus, complicating its natural expulsion and increasing the risk of retained placenta. Therefore, oxytocin is typically administered only after the placenta is delivered to avoid this complication.

Once the placenta has been expelled, oxytocin is used to help the uterus contract and reduce the risk of postpartum hemorrhage by promoting uterine firmness. These contractions help compress blood vessels at the placental attachment site, which minimizes blood loss and aids in postpartum recovery.

Imagine oxytocin like tightening a drawstring on a bag. If you tighten it too soon, it could trap things inside (like the placenta). Waiting to administer oxytocin until the placenta is out ensures the "drawstring" effect only happens once everything that needs to be removed is already out.

Nurses should ensure oxytocin is administered at the correct time to prevent complications and promote safe postpartum recovery.

• Wait to administer oxytocin until after the placenta has been fully delivered, as per protocol or physician instructions.
• Monitor the mother for signs of placental separation and complete expulsion before administering oxytocin.
• Once oxytocin is administered, observe for uterine firmness and monitor for excessive bleeding to prevent postpartum hemorrhage.
• Educate the mother on the purpose of oxytocin in helping the uterus contract and reduce bleeding after childbirth.
• Document the administration time of oxytocin and any observations related to the uterus and bleeding.

✘Incorrect answer options:

Oxytocin will help reduce bleeding. While it is true that oxytocin helps reduce postpartum bleeding by contracting the uterus, this is not the reason why it is given only after the placenta is delivered. The main concern is that early administration may cause the cervix to close prematurely, potentially trapping the placenta.

Oxytocin assists with the delivery of the placenta. Oxytocin is not typically given to assist with placental delivery itself. Natural uterine contractions after the birth of the baby generally aid in expelling the placenta. Oxytocin is administered after placental delivery to help the uterus contract and reduce bleeding.

Administering oxytocin ensures the placenta is fully expelled. Oxytocin does not directly ensure placental expulsion. If given too soon, it may actually hinder this process by causing the cervix to close before the placenta is fully delivered.

EXPLANATION

✔Correct answer:

Examine the placenta thoroughly to confirm it is complete, including all membranes. The first action Nurse Leah should take following the delivery of the placenta is to examine it thoroughly to ensure that it is complete, including all membranes. This assessment is crucial because any retained placental fragments in the uterus can lead to postpartum complications, such as hemorrhage and infection. By confirming that the placenta is intact, Nurse Leah can help prevent these potential issues and promote the mother's postpartum recovery.

The examination involves checking both the fetal (shiny) and maternal (rough) sides of the placenta, as well as ensuring that the amniotic membranes are complete. If any piece of the placenta or membrane is missing, it indicates the possibility of retained fragments in the uterus, which requires prompt medical intervention.

Think of the placenta like a completed puzzle. If a piece is missing, it means part of it might still be inside, causing potential problems. Nurse Leah’s job is to check that all "pieces" are there before moving on to the next steps.

Nurses should follow standardized procedures to ensure the placenta is thoroughly inspected and properly handled after delivery.

• Inspect both sides of the placenta and all membranes to ensure there are no missing pieces, which could indicate retained fragments.
• Document findings from the placental examination, noting if the placenta is complete or if any portions are missing.
• Place the placenta in a designated container for proper disposal or further pathological examination if needed.
• Label the container appropriately if the placenta requires identification or storage for any reason, such as cultural or medical requests.
• Educate the mother on the importance of assessing the placenta’s completeness to prevent postpartum complications.

✘Incorrect answer options:

Place the placenta in an appropriate container for disposal. While placing the placenta in a container for disposal is necessary, it should only be done after confirming that the placenta is complete. This ensures that any potential complications from retained fragments are avoided.

Properly label the placenta for identification. Labeling the placenta may be required if it needs to be stored or examined, but this is not the first priority. The primary concern is confirming placental completeness to prevent complications.

Leave the placenta in the kidney basin for the nursing aide to handle disposal. It is the nurse’s responsibility to examine the placenta for completeness before disposal. Leaving it for someone else without examining it could overlook retained fragments, leading to significant postpartum risks for the mother.

EXPLANATION

✔Correct answer:

30 minutes. The normal time frame for placental delivery during the third stage of labor is typically within 30 minutes after the baby is born. After the birth of the baby, the uterus continues to contract, which helps detach the placenta from the uterine wall and move it down into the birth canal. Placental separation and expulsion should ideally occur within this 30-minute period to minimize the risk of complications, such as postpartum hemorrhage or retained placenta.

If the placenta is not delivered within 30 minutes, it may be considered a retained placenta, which can increase the risk of bleeding and infection. In such cases, medical interventions may be required to manually or surgically remove the placenta.

Think of the placenta as the final act in a play. Once the main event (the baby’s birth) is over, the placenta's delivery is like the curtain coming down to officially close the show. Ideally, this curtain should come down within 30 minutes, wrapping up the entire process smoothly. If it takes longer, it’s like the audience waiting too long for closure, which could lead to problems and may require someone to step in to bring the curtain down manually.

Nurses should closely monitor the third stage of labor to ensure timely placental delivery and address any potential complications promptly.

• Monitor for signs of placental separation, such as a sudden gush of blood, lengthening of the umbilical cord, and a firm, globular shape of the uterus.
• If the placenta is not delivered within 30 minutes, notify the healthcare provider as further intervention may be required.
• Assess for uterine firmness and fundal height after placental expulsion to ensure the uterus is contracting properly and reducing the risk of hemorrhage.
• Educate the mother about the process of placental delivery and what to expect, providing reassurance as needed.
• Prepare for possible interventions, such as oxytocin administration, to promote uterine contractions and aid in placental expulsion.

✘Incorrect answer options:

5 minutes. While some placentas may be delivered within 5 minutes, this is not the typical time frame. A normal third stage can take up to 30 minutes without being considered prolonged.

45 minutes. If the placenta is not delivered within 30 minutes, it is generally considered prolonged or "retained." Waiting longer than 30 minutes increases the risk of complications, so 45 minutes is beyond the normal expected time frame.

60 minutes. A 60-minute delay in placental delivery is abnormal and can increase the risk of postpartum hemorrhage and infection. At this point, medical intervention is usually required to prevent complications.

EXPLANATION

✔Correct answer:

During an active uterine contraction. The most effective and safe time for a mother to bear down is during an active uterine contraction. Bearing down during contractions maximizes the force generated by both the mother’s pushing effort and the natural strength of the contraction, which helps to move the baby down the birth canal more efficiently. This coordinated effort reduces exhaustion and minimizes strain on both the mother and baby. Additionally, it helps prevent prolonged labor and reduces the risk of complications.

Timing is essential to prevent ineffective pushing. Encouraging the mother to push only during contractions also allows her to conserve energy in between contractions, which is especially important during the second stage of labor when pushing can be physically demanding.

Think of bearing down as rowing a boat—it's most effective when rowing with the flow of the river (the contraction). Rowing against the flow (in between contractions) would waste energy and not move the boat as efficiently.

Nurses play a key role in helping laboring mothers achieve effective and safe pushing during contractions. Here are some nursing actions to support this process:

• Encourage the mother to take deep breaths and focus on pushing only during contractions to maximize the effectiveness of each effort.
• Use verbal coaching to help the mother recognize the onset of a contraction and coordinate her pushes accordingly.
• Assist the mother in finding comfortable and effective positions for pushing, such as squatting or semi-sitting, to aid the descent of the baby.
• Provide emotional support and reassurance to keep the mother focused and encouraged during the pushing phase.
• Allow the mother to rest in between contractions to conserve energy, especially if the second stage of labor is prolonged.

✘Incorrect answer options:

When she feels pressure in the rectal area. While rectal pressure can be a sign that the baby is descending, it does not necessarily indicate the best time to push. Timing pushes with contractions is more effective for moving the baby down the birth canal.

In between contractions to avoid uterine rupture. Bearing down between contractions is ineffective because there is no uterine force to assist the push, and it does not prevent uterine rupture. Bearing down should coincide with contractions for maximum effectiveness and safety.

Whenever the mother feels the urge to push. The urge to push often aligns with contractions, but pushing should still be guided by the timing of contractions to ensure that efforts are coordinated and effective. Pushing without contractions can be exhausting and less productive.

EXPLANATION

✔Correct answer:

Schultze. The Schultze mechanism of placental delivery occurs when the fetal (shiny) side of the placenta is delivered first. In this type of delivery, the placenta separates centrally and then folds inward as it detaches, so the shiny, smooth, fetal side (covered by the amnion and chorion membranes) emerges first. This is often considered a cleaner type of delivery because there is usually less bleeding visible initially, as the separation begins from the center of the placenta and then proceeds to the edges.

In contrast, the Duncan mechanism involves the maternal (rough) side of the placenta being delivered first. This mechanism results in more visible bleeding because the placenta separates along its edges before detaching, exposing more of the blood vessels from the maternal side.

Imagine the placenta like a clean white napkin (the fetal side) sitting on a tablecloth with crumbs on one side (the maternal side). In the Schultze mechanism, it’s as if you’re lifting the napkin from the center, so the clean side comes up first, neatly hiding the crumbs until the very end. With the Duncan mechanism, it’s like peeling the napkin up from one edge, immediately exposing the crumb-covered side, leading to more mess as it separates.

Nurses should be prepared for either mechanism of placental delivery and understand that each type has specific characteristics:

• Observe for the type of placental separation (Schultze or Duncan) and monitor for signs of excessive bleeding.
• Ensure proper technique in managing the cord traction to avoid uterine inversion during placental delivery.
• Monitor the uterus post-delivery to ensure it remains firm and contracted to reduce the risk of hemorrhage.
• Document the type of placental delivery and inspect the placenta to confirm it is intact and complete.
• Provide reassurance and information to the mother about the placental delivery process, as it is often unfamiliar and can be surprising.

✘Incorrect answer options:

Ritgens. The Ritgen maneuver is a technique used to control the delivery of the fetal head, not the placenta. It involves applying gentle pressure to the perineum to assist the controlled birth of the baby’s head, helping to reduce the risk of perineal tearing.

Duncan. The Duncan mechanism describes placental delivery in which the maternal (rough) side of the placenta is delivered first. This type of delivery often involves more visible blood because separation starts at the edges of the placenta.

Marmets. The Marmet technique is a method for manually expressing breast milk, unrelated to placental delivery. It involves specific hand movements to encourage milk flow and is commonly taught to breastfeeding mothers.

EXPLANATION

✔Correct answer:

Two arteries and one vein. The typical structure of the umbilical cord includes two arteries and one vein. This unique arrangement is essential for supporting fetal development. The two umbilical arteries carry deoxygenated blood and waste products from the fetus back to the placenta, where these wastes are exchanged for oxygen and nutrients. The single umbilical vein then carries oxygenated, nutrient-rich blood from the placenta back to the fetus, providing necessary sustenance and promoting growth.

This configuration of vessels is surrounded by a gelatinous substance called Wharton’s jelly, which helps protect the blood vessels from compression and ensures a steady flow of blood between the fetus and placenta.

Think of the umbilical cord like a supply and waste system. The single vein is like a delivery pipe bringing fresh oxygen and nutrients to the baby, while the two arteries are like two drainage pipes carrying waste products back to the placenta for removal.

Nurses should educate expectant mothers about the umbilical cord's function and reassure them about its protective features. If any abnormalities in the umbilical cord structure are detected on ultrasound, further assessments may be required.

• Explain the role of the umbilical cord in providing oxygen and nutrients to the fetus and removing waste.
• Monitor for any signs of umbilical cord abnormalities (e.g., single umbilical artery), which may require further investigation and monitoring.
• Educate on the importance of prenatal care and ultrasound exams for monitoring fetal health and detecting any cord-related issues early on.
• Provide information about the role of Wharton’s jelly in protecting the umbilical vessels from compression.
• Reassure expectant mothers about the normal structure of the umbilical cord and address any questions or concerns.

✘Incorrect answer options:

Two veins and one artery. This is incorrect because the normal umbilical cord structure includes only one vein and two arteries. The single vein is responsible for bringing oxygenated blood to the fetus, while the two arteries carry deoxygenated blood away from the fetus.

Two arteries and two veins. This is also incorrect. The umbilical cord typically has only three blood vessels—two arteries and one vein. The presence of more than three vessels is rare and would be considered an anomaly.

None of the above. This option is incorrect because the correct answer, "two arteries and one vein," is provided among the choices.

EXPLANATION

✔Correct answer:

Fluid intake and output. Fluid intake and output (I&O) is not typically monitored on a partograph. The partograph is a tool designed primarily to track the progress of labor, focusing on maternal and fetal well-being as well as labor progression. The main parameters recorded on a partograph include vital signs, uterine contractions, fetal heart rate, cervical dilation, and descent of the fetal head.

While monitoring fluid intake and output can be important for overall maternal health during labor, it is generally recorded separately from the partograph. Tracking I&O may be necessary in certain clinical situations, such as cases of preeclampsia, dehydration, or when IV fluids are administered, but it is not a standard component of the partograph.

Think of the partograph as a specific "road map" to track the progress of labor. It focuses on checkpoints related to labor, like how far along the cervix is dilated and how strong the contractions are. Fluid intake and output would be like tracking gas or food intake on a separate log, important but not directly related to the map of labor progression.

Nurses should be familiar with the key components of the partograph and understand its importance in monitoring labor progression.

• Record cervical dilation regularly on the partograph to track the labor’s progress against expected norms.
• Monitor and document uterine contractions, including frequency, duration, and strength, to assess labor activity.
• Observe and record maternal vital signs, such as temperature, pulse, and blood pressure, to detect signs of distress or complications.
• Track fetal heart rate on the partograph to monitor fetal well-being throughout labor.
• Record fluid intake and output separately if clinically indicated, such as in cases of prolonged labor or specific maternal health conditions.

✘Incorrect answer options:

Vital signs. Maternal vital signs, including temperature, pulse, and blood pressure, are routinely monitored on the partograph to help detect any signs of maternal distress or complications during labor.

Uterine contractions. Uterine contractions are a key element recorded on the partograph. Documenting the frequency, duration, and strength of contractions is essential to assess the labor's progression and ensure the uterus is contracting effectively.

Cervical dilation. Cervical dilation is one of the primary parameters recorded on the partograph, as it indicates how far along labor has progressed. Measuring and recording cervical dilation allows healthcare providers to identify any delays or issues with labor progression.

EXPLANATION

✔Correct answer:

First stage. The first stage of labor, which lasts from the onset of labor contractions until full cervical dilation (10 cm), typically shows the most pronounced differences between primigravida (first-time mothers) and multigravida (those who have previously given birth) patients.

In primigravidas, cervical effacement (thinning) usually happens before significant dilation, which can result in a longer latent phase of labor. For multigravidas, the cervix often effaces and dilates simultaneously, leading to a generally faster progression through both the latent and active phases of the first stage. Therefore, the first stage tends to be significantly shorter for multigravidas compared to primigravidas, especially in the early phases.

• First Stage (Latent and Active Phases): Primigravidas often have a prolonged latent phase due to the sequential pattern of effacement first, followed by dilation. This can extend the overall length of the first stage. Multigravidas, on the other hand, usually have more efficient cervical changes, often with effacement and dilation happening together, leading to a quicker first stage.
• Second Stage (Pushing and Delivery): While the second stage can be shorter for multigravidas, the difference is typically less significant compared to the first stage.
• Third Stage (Delivery of Placenta): The third stage usually progresses similarly for both primigravidas and multigravidas, lasting around 5-30 minutes.
• Fourth Stage (Immediate Postpartum): The fourth stage involves monitoring for complications, and there are no major differences between primigravidas and multigravidas during this period.

Think of the first stage of labor as a long hallway with doors that open one at a time for primigravidas, but open together for multigravidas. This makes the journey through the hallway (first stage) faster for multigravidas.

Nurses should be prepared to offer different support for primigravidas versus multigravidas during the first stage of labor. Here are some key nursing interventions:

• Encourage relaxation techniques and provide comfort measures for primigravidas, who may experience a longer labor process.
• Regularly assess cervical dilation and effacement to monitor progression, especially during the latent phase of labor.
• For multigravidas, monitor closely as they may progress more rapidly through the first stage, particularly the active phase.
• Educate the patient and family members about expected labor progression based on whether the patient is primigravida or multigravida.
• Offer reassurance and support, as prolonged latent labor in primigravidas can be challenging and may lead to feelings of frustration or anxiety.

✘Incorrect answer options:

Second stage. While multigravidas often have a shorter second stage due to their previous birthing experience, the difference is generally less pronounced than in the first stage. Both primigravidas and multigravidas can experience variable lengths in the second stage, which involves the active pushing phase until delivery of the baby.

Third stage. The third stage of labor, which involves the delivery of the placenta, typically lasts about the same length of time (5-30 minutes) for both primigravidas and multigravidas.

Fourth stage. The fourth stage, or immediate postpartum period, involves monitoring maternal vital signs and assessing for postpartum complications. There are no significant differences between primigravidas and multigravidas during this stage.

EXPLANATION

✔Correct answer:

1.2 cm per hour. The average rate of cervical dilation for a nulliparous woman (a woman who has not given birth before) in the active phase of the first stage of labor is approximately 1.2 cm per hour. This rate of dilation is generally slower for first-time mothers compared to multiparous women (those who have previously given birth), who typically dilate at an average rate of around 1.5 cm per hour. This difference is attributed to the fact that the cervix and surrounding tissues have not yet been stretched by previous deliveries in nulliparous women, which often makes the process slower.

The active phase of the first stage of labor usually begins when the cervix is dilated to about 6 cm and continues until it reaches full dilation at 10 cm. Monitoring the rate of dilation helps healthcare providers assess the labor’s progress and determine if it is within the expected range, or if there are signs of dysfunctional labor, which may require intervention.

Think of cervical dilation like opening a new jar with a tight lid. The first time you open it (nulliparous labor), it takes a bit longer and more effort. In later uses (multiparous labor), the lid tends to loosen and open faster. Similarly, the cervix typically dilates more slowly for first-time mothers.

Nurses play a critical role in monitoring labor progression and supporting patients through each stage.

• Regularly assess cervical dilation to ensure labor is progressing within expected parameters.
• Monitor the mother’s vital signs and fetal heart rate to ensure both mother and baby are tolerating labor well.
• Provide emotional support and comfort measures to help the mother manage contractions and stay relaxed during labor.
• Educate the mother about the labor process, including expected progress rates and any signs that may indicate labor is moving more slowly.
• Communicate findings to the healthcare provider if labor progress deviates from the expected rate, as this may necessitate interventions to support labor.

✘Incorrect answer options:

1.5 cm per hour. This is the average rate of dilation for a multiparous woman, not a nulliparous woman. Multiparous women typically dilate faster due to the cervix being previously stretched from prior births.

1.8 cm per hour. This rate of dilation is faster than the typical range for both nulliparous and multiparous women in the active phase of labor. It is not the standard expected rate.

2.0 cm per hour. This rate is also faster than average and is not typical for nulliparous women, who generally progress at a slower rate than this.

EXPLANATION

✔Correct answer:

Station 0. Station 0 is used to document the position of the fetal head when it is at the level of the ischial spines. The ischial spines are bony landmarks located within the pelvis, and they serve as a reference point for determining the station of the fetus during labor.

Station measurements describe the descent of the fetal head in relation to these ischial spines, with 0 station meaning the head is aligned with the ischial spines, indicating that the baby is at "engagement." Positive numbers (+1, +2, etc.) indicate that the fetal head is descending below the ischial spines and moving closer to delivery. Negative numbers (-1, -2, etc.) indicate that the fetal head is still above the ischial spines.

Think of the ischial spines as a halfway mark on a hill. If the fetal head is at the ischial spines (Station 0), it’s reached the midpoint. Anything above Station 0 is like being higher up the hill (negative stations), while anything below Station 0 means the baby is descending downhill toward birth (positive stations).

Understanding and documenting fetal station is important for assessing labor progress and ensuring timely interventions if needed.

• Regularly assess fetal station during labor to determine the progress of fetal descent.
• Document the station accurately in the patient’s record, as it provides vital information on labor progression.
• Inform the mother and her support team about the baby’s progress, which can help provide reassurance and motivation during labor.
• Be prepared to assist with positioning techniques or other interventions that can help facilitate fetal descent.
• Report any lack of progress in fetal descent to the healthcare provider, as it may indicate a need for further assessment or intervention.

✘Incorrect answer options:

Station -1. Station -1 indicates that the fetal head is 1 cm above the ischial spines, not at the level of the ischial spines.

Station +1. Station +1 indicates that the fetal head is 1 cm below the ischial spines, indicating further descent past the level of engagement.

Station +2. Station +2 indicates that the fetal head is 2 cm below the ischial spines, signifying even further descent toward delivery.

EXPLANATION

✔Correct answer:

Starts with complete dilation and effacement of the cervix and ends with the delivery of the baby. The second stage of labor begins when the cervix is fully dilated (10 cm) and fully effaced (thinned out). This stage marks the transition from labor to the active pushing phase. The end point of the second stage is the delivery of the baby. During this stage, the mother actively pushes with contractions to help move the baby through the birth canal and out of the body.

The second stage can vary in duration, often lasting longer for first-time mothers (primigravidas) compared to those who have given birth before (multigravidas). For both groups, this stage is highly physically demanding, as it involves the most active participation from the mother and requires careful monitoring by healthcare providers to ensure both maternal and fetal well-being.

Think of the second stage as the final lap in a marathon, where the runner (the mother) gives a final push to reach the finish line (delivery of the baby). The lap begins at full dilation (start line) and ends when she crosses the finish line with the baby in her arms.

Nurses play a critical role in supporting the mother during the second stage of labor. Here are some key nursing interventions to consider:

• Encourage effective pushing techniques, such as using abdominal muscles and timing pushes with contractions to maximize effectiveness.
• Provide emotional support and encouragement, as this stage can be exhausting and stressful for the mother.
• Monitor fetal heart rate closely to assess fetal well-being during pushing efforts.
• Offer comfort measures, such as repositioning, cool compresses, and controlled breathing techniques.
• Prepare necessary equipment and supplies for the delivery to ensure a smooth transition once the baby is born.

✘Incorrect answer options:

Starts with full cervical dilation and ends with the delivery of the placenta. This option is incorrect because the delivery of the placenta marks the end of the third stage of labor, not the second stage. The second stage ends with the delivery of the baby, while the third stage begins immediately after the baby's birth and ends once the placenta is delivered.

Starts with true labor contractions and ends with the birth of the baby. This is incorrect because true labor contractions are part of the first stage of labor, not the second stage. The second stage begins only after the cervix is fully dilated and effaced.

Starts with the appearance of a "show" and ends with full cervical dilation and effacement. This option is also incorrect. The appearance of a "show" (bloody show) indicates that the cervix is beginning to dilate, and it is typically seen during the first stage of labor. The second stage begins only after complete cervical dilation and effacement, and it ends with the delivery of the baby.

EXPLANATION

✔Correct answer:

Retractor. A retractor is not typically included in a basic delivery set for a normal vaginal birth. Retractors are surgical instruments used to hold back tissue or organs to gain access to a particular area of the body, more commonly in surgical procedures or cesarean sections where deeper access is needed. In a routine vaginal delivery, there is generally no need for a retractor, as the vaginal canal and perineal area are accessible without it.

A basic delivery set for a vaginal birth typically includes items like two clamps to clamp the umbilical cord, a pair of scissors to cut the cord, and a kidney basin to catch fluids or placenta. These items are essential for the basic steps involved in a normal delivery, such as clamping and cutting the umbilical cord and managing fluids.

Think of a basic delivery set like a toolkit for changing a tire on a car—you need a jack, a lug wrench, and a spare tire. Adding a retractor would be like adding a specialized tool for engine repair—not necessary for the job at hand.

Nurses should be familiar with the standard instruments required for a normal vaginal delivery and ensure all necessary items are prepared and sterile.

• Ensure that all items in the basic delivery set are sterile and within reach for the provider during the delivery.
• Set up clamps and scissors in a sterile manner to facilitate quick clamping and cutting of the umbilical cord once the baby is delivered.
• Have the kidney basin nearby to manage any bodily fluids and the placenta after delivery.
• Be prepared with additional supplies, such as gauze, sterile drapes, and sutures, in case of perineal tears or minor lacerations that may need repair.
• Maintain a calm and organized delivery environment to ensure a safe and efficient birth process.

✘Incorrect answer options:

Two clamps. Clamps are essential in a delivery set to secure the umbilical cord after birth. Two clamps are usually used—one placed close to the baby and the other further away on the cord—before cutting between them.

A pair of scissors. Scissors are necessary for cutting the umbilical cord after it is clamped. They are a standard part of the delivery set.

Kidney basin. A kidney basin is commonly included in a delivery set to catch fluids, blood, and the placenta after delivery. It is an essential item for cleanliness and organization in the delivery area.

EXPLANATION

✔Correct answer:

Ritgen’s technique. Ritgen’s technique is a method used during delivery to help control the baby's head as it crowns, while also providing support to the mother’s perineum to minimize the risk of tearing. In this technique, the healthcare provider uses one hand to apply gentle pressure on the perineum to support the tissue, while the other hand may be used to control the baby's head, allowing it to emerge slowly and gently. This controlled delivery helps prevent rapid expulsion, which can lead to perineal tears.

The goal of Ritgen’s technique is to help guide the baby’s head and protect the perineal tissues, reducing the likelihood of lacerations or the need for an episiotomy. It is particularly useful in the final moments of delivery as the head crowns and stretches the perineum.

Imagine trying to ease a tight glove over your hand—you go slowly, stretching the glove a bit at a time to avoid tearing it. Similarly, Ritgen's technique involves gently guiding the baby's head as it crowns, allowing the mother's perineum to stretch gradually. This controlled approach helps prevent sudden strain on the tissue, reducing the risk of tearing, just as easing the glove on prevents ripping the fabric.

Nurses should be familiar with Ritgen’s technique to assist during the crowning stage of delivery effectively.

• Support the perineum with gentle pressure to reduce stress on the tissue as the head crowns.
• Guide the baby’s head to emerge slowly, allowing the perineum to stretch gradually and decreasing the risk of tearing.
• Communicate with the mother to encourage controlled pushing efforts in alignment with this technique.
• Observe for any signs of excessive perineal tension and be prepared to offer additional support if needed.
• Prepare for immediate postpartum care in case of any minor tears or perineal trauma despite preventive efforts.

✘Incorrect answer options:

Marmet’s technique. The Marmet technique is a method used for manual breast milk expression, not for delivery. It involves specific hand movements to help release milk from the breast, primarily used by mothers who are breastfeeding or pumping.

Duncan maneuver. The Duncan mechanism is a type of placental delivery where the maternal side of the placenta (rough side) comes out first. It is unrelated to perineal support during crowning.

Schultze maneuver. The Schultze mechanism refers to a different type of placental delivery, where the fetal (shiny) side of the placenta is delivered first. It is not associated with supporting the perineum during the delivery of the baby’s head.

EXPLANATION

✔Correct answer:

Contraction length gradually increases with time. Increasing contraction length and intensity over time is a characteristic of true labor, not false labor. In true labor, contractions become progressively stronger, longer, and closer together, indicating that the body is preparing for childbirth. This gradual increase in contraction duration and intensity helps to dilate and efface (thin out) the cervix, ultimately leading to delivery.

In contrast, false labor (often referred to as Braxton Hicks contractions) is characterized by irregular contractions that do not increase in duration, intensity, or frequency over time. False labor contractions are typically mild, inconsistent, and may diminish with changes in activity or position, unlike true labor contractions, which continue to progress.

Think of true labor contractions as an uphill climb where the effort steadily increases as you get closer to the peak (delivery). False labor, on the other hand, is like a few short steps on a treadmill: it doesn’t lead to a peak (cervical change), and the intensity and duration don’t increase over time.

When assessing a pregnant patient for signs of true vs. false labor, it is important to conduct a thorough evaluation, including contraction patterns, cervical changes, and other physical signs.

• Assess the contraction pattern, duration, and intensity to determine if they are regular and progressively increasing, which would indicate true labor.
• Evaluate cervical changes, such as dilation and effacement, as these occur in true labor but not in false labor.
• Monitor for additional signs of true labor, such as bloody show (vaginal discharge mixed with blood), which suggests cervical changes.
• Encourage the patient to rest, hydrate, and change positions if experiencing false labor, as these activities may reduce Braxton Hicks contractions.
• Provide patient education on recognizing signs of true labor and when to seek medical attention, especially if contractions become regular and intense.

✘Incorrect answer options:

The contractions vary in intensity and timing. In false labor, contractions are typically irregular and vary in intensity, making this a characteristic of false labor rather than true labor. True labor contractions, in contrast, follow a regular pattern and gradually become stronger and more frequent.

No presence of a bloody vaginal discharge. False labor contractions do not cause cervical changes, and as a result, there is no bloody vaginal discharge or "bloody show." Bloody show is usually seen in true labor as the cervix begins to dilate and thin out, releasing the mucus plug mixed with blood.

The cervix remains closed and unchanged. False labor does not lead to cervical dilation or effacement. In true labor, contractions result in progressive changes to the cervix, including dilation (opening) and effacement (thinning). The lack of cervical change is thus a hallmark of false labor.

EXPLANATION

✔Correct answer:

Floating. The correct term to describe a fetal presenting part that is still mobile and not yet settled into the mother’s pelvis is "floating." When the presenting part (typically the fetal head) is floating, it means it is still above the level of the ischial spines and has not yet begun to engage in the pelvis. In this stage, the fetal head can be easily moved or displaced with palpation, indicating that engagement has not occurred.

Engagement occurs when the largest diameter of the fetal presenting part reaches or passes through the pelvic inlet, typically at station 0 (level of the ischial spines). Once engaged, the presenting part is usually fixed and not easily movable. A floating fetus, on the other hand, is not yet in this position and remains more mobile within the uterine cavity.

Think of the pelvis like a bucket. If an object (the fetal head) is floating above the bucket, it’s not yet settled in place and can be easily moved. Once it settles into the bucket (engagement), it becomes fixed and harder to shift.

Nurses should accurately assess fetal position and engagement status during labor to monitor labor progress and identify any delays.

• Document the fetal station and engagement status accurately, noting if the presenting part is floating or engaged.
• Educate the mother on the meaning of engagement and how it indicates the progress of labor, explaining that a floating presenting part means the baby is not yet fully positioned in the pelvis.
• Encourage walking or other position changes if appropriate, as these can sometimes promote fetal descent and engagement.
• Monitor for signs of labor progression, as a floating presenting part may indicate that labor is still in the early stages.
• Report to the healthcare provider if there is no progress toward engagement over time, as this may require further assessment.

✘Incorrect answer options:

Engaged. Engagement refers to the point when the presenting part has descended into the pelvis and reached the level of the ischial spines (station 0). An engaged presenting part is generally fixed and not mobile, so this term does not describe a mobile presenting part.

Descended. Descended simply means that the fetus has moved downwards, but it does not specifically indicate whether the presenting part is mobile or engaged. A floating fetal head can still be considered descended but would not yet be engaged.

Internal Rotation. Internal rotation refers to the turning of the fetal head to align with the maternal pelvis as labor progresses, usually in preparation for descent. This term does not describe the mobility or engagement of the fetal presenting part.

EXPLANATION

✔Correct answer:

Check if the umbilical cord is wrapped around the neck. As the baby's head emerges during delivery, Nurse Carla's immediate action should be to check for a nuchal cord—a condition where the umbilical cord is wrapped around the baby’s neck. This is a common occurrence and, if present, needs to be addressed before proceeding with further delivery steps. If a nuchal cord is found, the nurse or provider can gently attempt to slip it over the baby's head. If it is too tight to slip over, it may need to be clamped and cut to prevent constriction during the delivery of the shoulders and body.

Assessing for a nuchal cord is critical because it can restrict blood flow to the baby if left unmanaged during delivery. Once it is confirmed that the neck is clear, the nurse or provider can proceed with other steps, such as suctioning the baby's mouth and nose if needed, and assisting with the delivery of the shoulders.

Think of the umbilical cord like a scarf. If someone is wearing it loosely, it’s safe, but if it’s tight around their neck, it needs to be loosened or removed. Similarly, checking the baby’s neck for a tight umbilical cord during birth ensures there’s no restriction before the rest of the body is delivered.

Nurses play a critical role in ensuring a safe delivery, especially in cases where there might be a nuchal cord.

• Check for the presence of a nuchal cord immediately as the baby’s head emerges to prevent potential complications.
• If the cord is loose, gently slip it over the baby’s head; if it’s tight, prepare to clamp and cut the cord before proceeding.
• After ensuring the neck is clear, suction the mouth and nose to clear any fluids that could affect breathing.
• Assist with the delivery of the shoulders, usually starting with the anterior shoulder to help facilitate a smooth delivery.
• Monitor the baby's color and breathing immediately after birth to assess for any complications related to a nuchal cord.

✘Incorrect answer options:

Clamp and cut the umbilical cord. This is incorrect because the umbilical cord should not be clamped and cut immediately as the head emerges unless it is necessary to release a tight nuchal cord. Typically, clamping and cutting are done after the entire baby is delivered.

Clean the baby’s face and suction the mouth first. Suctioning the baby’s mouth and nose is important but should come after ensuring that the umbilical cord is not around the neck. Suctioning will help clear fluids from the airway but is secondary to checking for a nuchal cord.

Assist with the delivery of the anterior shoulder. Assisting with the delivery of the anterior shoulder is also necessary, but only after checking for and addressing any nuchal cord. Ensuring the neck is clear of the cord takes priority to avoid complications during shoulder and body delivery.

EXPLANATION

✔Correct answer:

Full bladder. A full bladder is a common cause of dysfunctional labor that Nurse Liana can address independently. When the bladder is full, it can impede the descent of the fetal head and interfere with effective uterine contractions, leading to labor inefficiency. By assisting the patient to empty her bladder, either by encouraging her to use the restroom or, if necessary, using a catheter, Nurse Liana can help relieve this obstruction and potentially improve labor progression.

Other causes of dysfunctional labor, such as pelvic bone contraction, extension rather than flexion of the fetal head, and cervical rigidity, are not issues that can be managed solely by nursing interventions. These causes often require medical or obstetric interventions, such as repositioning techniques, use of labor-assisting tools, or, in some cases, surgical intervention (e.g., cesarean section).

Think of labor as a hallway the baby must pass through. A full bladder is like a piece of furniture blocking the hallway, which the nurse can easily move to clear the path. Other issues, like the shape of the hallway itself, would require structural changes, not just simple adjustments.

Nurses can take several steps to support patients experiencing dysfunctional labor, especially when a full bladder may be contributing to the issue.

• Encourage regular bladder emptying, as a full bladder can interfere with fetal descent and contraction effectiveness.
• Assist the patient to the restroom or provide a bedpan if she is unable to ambulate comfortably.
• Consider catheterization if the patient is unable to void, especially if she has received epidural anesthesia, which can reduce the sensation of bladder fullness.
• Monitor for signs of dysfunctional labor, such as prolonged contractions with little progress, and report findings to the healthcare provider.
• Provide education to the patient on the importance of bladder emptying during labor to support effective contractions and fetal descent.

✘Incorrect answer options:

Pelvic bone contraction. Pelvic bone contraction (a narrowed or contracted pelvis) is a structural issue that cannot be managed by a nurse alone. It may require obstetric interventions, such as a cesarean section, if the fetal head cannot pass through the birth canal due to the pelvic shape.

Extension rather than flexion of the head. Malposition of the fetal head, such as extension rather than flexion, can lead to dysfunctional labor but typically requires medical or obstetric interventions, such as repositioning techniques, manual rotation, or, if necessary, assisted delivery methods.

Cervical rigidity. Cervical rigidity, or a cervix that is slow to dilate and efface, can contribute to prolonged labor. However, it cannot be resolved independently by the nurse. Medical interventions, such as oxytocin administration, may be required to help the cervix progress.

EXPLANATION

✔Correct answer:

The mother has a strong urge to bear down. A strong urge to bear down is not a typical sign of placental detachment. This sensation is usually associated with the second stage of labor, when the baby is descending through the birth canal and the mother is actively pushing to deliver the baby. In the third stage of labor, the focus is on the delivery of the placenta, and the urge to bear down is generally not a common indication of placental separation.

The third stage of labor involves the separation and delivery of the placenta. Classic signs of placental separation include:

• Lengthening of the umbilical cord as the placenta detaches and moves down toward the vaginal opening.
• A globular and firmer shape of the uterus as it contracts around the detached placenta.
• A sudden gush of blood indicating that the placenta has separated from the uterine wall, causing blood to escape from the site where it was attached.

Imagine the placenta as a picture frame hanging on a wall by a sticky adhesive. When the adhesive loosens (placental detachment), the frame tilts forward, making the hanging cord appear longer (lengthening of the umbilical cord). As it pulls away, some dust or paint might flake off (a sudden release of blood), and the wall behind it may look slightly different in shape (the uterus becomes firmer and globular). There’s no need for an extra push to remove it – it simply detaches on its own.

Nurses should monitor for these signs to confirm placental separation and provide timely intervention if necessary. Here are some nursing actions during the third stage:

• Observe for signs of placental separation, such as lengthening of the umbilical cord and a firm, globular uterus.
• Monitor for a sudden release of blood, which can indicate placental detachment.
• Assist in the controlled delivery of the placenta to prevent excessive bleeding and avoid uterine inversion.
• Ensure the uterus remains firm after placenta delivery to minimize postpartum hemorrhage risk.
• Provide reassurance and support to the mother, explaining the normal process of placental delivery.

✘Incorrect answer options:

The umbilical cord appears longer. This is a typical sign of placental separation. As the placenta detaches from the uterine wall, it moves downwards, causing the umbilical cord to appear longer at the vaginal opening.

The uterus takes on a more globular shape. A firm and globular uterus is a sign that the placenta has separated and the uterus is contracting around the detached placenta, indicating readiness for placental expulsion.

There is a sudden release of blood. A sudden gush of blood is a common sign of placental separation, as blood from the detachment site exits through the vaginal opening. This bleeding is normal but should be monitored closely to prevent hemorrhage.

EXPLANATION

✔Correct answer:

Administer a prescribed antacid medication before surgery. Administering a prescribed antacid before surgery helps to neutralize stomach acid, thereby reducing the risk of aspiration pneumonitis if gastric contents were accidentally inhaled during the procedure. Aspiration of stomach contents is a potential risk during anesthesia, particularly in cesarean sections, where intra-abdominal pressure is increased due to pregnancy. The antacid reduces the acidity of any stomach contents, making them less harmful if aspiration occurs.

Aspiration during surgery can lead to serious complications, including chemical pneumonitis, so it is standard practice to reduce stomach acidity as a preventive measure. Alongside fasting guidelines, the use of antacid medication is an evidence-based approach to minimizing aspiration risks during cesarean deliveries.

Think of the antacid as a way to "water down" the stomach’s acid, similar to diluting a strong vinegar. If a small amount spills (is aspirated), it’s less likely to cause harm. Without the antacid, any spillage could cause more severe irritation (aspiration pneumonitis).

Nurses preparing a patient for a cesarean section should follow preoperative protocols to minimize risks such as aspiration.

• Administer the prescribed antacid medication at the appropriate time before surgery, as ordered.
• Educate the patient on the importance of following fasting guidelines, typically avoiding solid foods for 6-8 hours and clear liquids for 2 hours before surgery.
• Position the patient with a slight head elevation if needed preoperatively to further reduce aspiration risk.
• Assess the patient for any factors that may increase aspiration risk, such as obesity or GERD, and communicate these to the surgical team.
• Monitor for signs of nausea and communicate with anesthesia if the patient experiences preoperative discomfort that may increase aspiration risk.

✘Incorrect answer options:

Instruct the patient to have a full breakfast the morning of surgery for energy. Eating a full breakfast before surgery increases the risk of aspiration because the stomach will still contain food. Patients are typically instructed to fast for a certain period before surgery to minimize stomach contents and reduce the aspiration risk.

Position the patient flat on the back on the operating table. Positioning the patient flat on the back can actually increase aspiration risk due to increased intra-abdominal pressure and the risk of reflux, especially in pregnant patients. Positioning with slight head elevation is often preferred preoperatively if possible.

Encourage the patient to drink clear liquids up to an hour before the procedure. Drinking clear liquids up to an hour before surgery is not recommended as it may leave residual contents in the stomach, increasing aspiration risk. Typically, clear liquids are permitted up to 2 hours before surgery, but fasting guidelines should always be followed closely.
