Congestive Heart Failure (CHF) Nursing Care Plan & Management

Notes

Description
  • Congestive Heart Failure or CHF is a severe circulatory congestion due to decreased myocardial contractility, which results in the heart’s inability to pump sufficient blood to meet the body’s needs.CHF
  • About 80% of CHF cases occur before 1 year of age
Etiology
  1. The primary cause of CHF in the first 3 years of life is CHD.
  2. Other causes in children include:
    • Other myocardial disorders, such as cardiomyopathies, arrhythmias, and hypertension
    • Pulmonary embolism or chronic lung disease
    • Severe hemorrhage or anemia
    • Adverse effects of anesthesia or surgery
    • Adverse effects of transfusions or infusions
    • Increased body demands resulting from conditions such as fever, infection and arteriovenous fistula
    • Adverse effects of drugs, such as doxorubicin
    • Severe physical or emotional stress
    • Excessive sodium intake
  3. In general, causes can be classified according to the following:
    • Volume overload may cause the right ventricle to hypertrophy to compensate for added volume.
    • Pressure overload usually results from an obstructive lesion, such as COA
    • Decrease contractility can result from problems such as sever anemia, asphyxia, heart block and acidemia.
    • High cardiac output demands occur when the body’s need for oxygen exceeds the heart’s output s seen in sepsis and hyperthyroidism.
Pathophysiology
  • Right ventricular failure occurs when the right ventricle is unable to pump blood into the pulmonary circulation. Less blood is oxygenated and pressure increases in the right atrium and systemic venous circulation, which results in edema of the extremities.
  • Left ventricular failure occurs when the left ventricle in unable to pump blood into systemic circulation. Pressure increases in the left atrium and pulmonary veins; then the lungs become congested with blood, causing elevated pulmonary pressure and pulmonary edema.
  • To compensate, the cardiac muscle hypertrophies eventually resulting in decreased ventricular compliance. Decreased compliance requires higher filling pressure to produce the same stroke volume. Increased muscle mass impedes oxygenation of the heart muscle, which leads to decreased contraction force and heart failure.
  • As cardiac output fails, stretch receptors and baroreceptors stimulate the sympathetic nervous system, releasing catecholamines that increase the force and rate of myocardial contraction.
  • This causes increased systemic resistance, increased venous return, and reduced blood flow to the limbs, viscera and kidneys.
  • Sweating results from sympathetic cholinergic fibers, there is extra work for the heart muscle, and there is less systemic blood flow.
  • The renal system responds by releasing renin-angiotensin, which sets off a chain of events – vasoconstriction, leading to increased aldosterone release, causing sodium and water retention and, in turn, increasing preload. Finally, sodium and water retention becomes excessive, resulting in signs of systemic venous congestion and fluid overload.

  2. CBC reveals dilution hyponatremia, hypochloremia, and hyperkalemia
  3. ECG reveals ventricular hypertrophy
Primary Nursing Diagnosis
  • Decreased CO related to an ineffective ventricular pump
Medical Management
  • Initial management of the patient with HF depends on severity of HF, seriousness of symptoms, etiology, presence of other illnesses, and precipitating factors. Medication management is paramount in patients with HF. The general principles for management are treatment of any precipitating causes, control of fluid and sodium retention, increasing myocardial contractility, decreasing cardiac workload, and reducing pulmonary and systemic venous congestion. The physician may also prescribe fluid and sodium restriction in an attempt to reduce volume and thereby reduce preload.
Surgical Management
  • Coronary bypass surgery, PTCA, other innovative therapies as indicated (e.g, mechanical assist devices , transplantation)
Pharmacologic Intervention

Alone or in combination: vasodilator therapy (angiotensin-converting enzyme (ACE) inhibitors), angiotensin II receptor blockers (ARBs), select beta-blockers, calcium channel blockers, diuretic therapy, cardiac glycosides (digitalis), and others

  • Dobutamine, milrinone, anticoagulants, beta-blockers, as indicated
  • Possibly antihypertensives or antianginal medications and anticoagulants
Nursing Intervention
  1. Monitor for signs of respiratory distress
    • Provide pulmonary hygiene as needed

Nursing Care Plan

Decreased Cardiac Output
Assessment

The patient may manifest the following:

  • Pale conjunctiva, nail beds, and buccal mucosa
  • irregular rhythm of pulse
  • bradycardia
  • generalized weakness
Diagnosis
  • Decreased cardiac output r/t [altered heart rate and rhythm] AEB [bradycardia]
Planning
  • Short Term: After 3-4 hours of nursing interventions, the patient will participate in activities that reduce the workload of the heart.
  • Long Term: After 2-3 days of nursing interventions, the patient will be able to display hemodynamic stability.
Nursing Interventions
  • Assess for abnormal heart and lung sounds.
    • Rationale: Allows detection of left-sided heart failure that may occur with chronic renal failure patients due to fluid volume excess as the diseased kidneys are unable to excrete water.
  • Monitor blood pressure and pulse.
    • Rationale: Patients with renal failure are most often hypertensive, which is attributable to excess fluid and the initiation of the rennin-angiotensin mechanism.
  • Assess mental status and level of consciousness.
    • Rationale: The accumulation of waste products in the bloodstream impairs oxygen transport and intake by cerebral tissues, which may manifest itself as confusion, lethargy, and altered consciousness.
  • Assess patient’s skin temperature and peripheral pulses.
    • Rationale: Decreased perfusion and oxygenation of tissues secondary to anemia and pump ineffectiveness may lead to decreased in temperature and peripheral pulses that are diminished and difficult to palpate.
  • Monitor results of laboratory and diagnostic tests.
    • Rationale: Results of the test provide clues to the status of the disease and response to treatments.
  • Monitor oxygen saturation and ABGs.
    • Rationale: Provides information regarding the heart’s ability to perfuse distal tissues with oxygenated blood
  • Give oxygen as indicated by patient symptoms, oxygen saturation and ABGs.
    • Rationale: Makes more oxygen available for gas exchange, assisting to alleviate signs of hypoxia and subsequent activity intolerance.
  • Implement strategies to treat fluid and electrolyte imbalances.
    • Rationale: Decreases the risk for development of cardiac output due to imbalances.
  • Administer cardiac glycoside agents, as ordered, for signs of left sided failure, and monitor for toxicity.
    • Rationale: Digitalis has a positive isotropic effect on the myocardium that strengthens contractility, thus improving cardiac output.
  • Encourage periods of rest and assist with all activities.
    • Rationale: Reduces cardiac workload and minimizes myocardial oxygen consumption.
  • Assist the patient in assuming a high Fowler’s position.
    • Rationale: Allows for better chest expansion, thereby improving pulmonary capacity.
  • Teach patient the pathophysiology of disease, medications
    • Rationale: Provides the patient with needed information for management of disease and for compliance.
  • Reposition patient every 2 hours
    • Rationale: To prevent occurrence of bed sores
  • Instruct patient to get adequate bed rest and sleep
    • Rationale: To promote relaxation to the body
  • Instruct the SO not to leave the client unattended
    • Rationale: To ensure safety and reduce risk for falls that may lead to injury
Evaluation
  • After nursing interventions, the patient shall have participated in activities that reduce the workload of the heart.
  • After 2-3 days of nursing interventions, the patient shall have been able to display hemodynamic stability.

Excess Fluid Volume
Assessment

The patient may manifest the following:

  • Edema of extremities
  • Difficulty of breathing
  • Crackles
  • Change in mental status
  • Restlessness and anxiety
Diagnosis
  • Excessive Fluid volume related to decreased cardiac output and sodium and water retention
Planning & Desired Outcomes
  • Patient will verbalize understanding of causative factors and demonstrate behaviors to resolve excess fluid volume.
  • Patient will demonstrate adequate fluid balanced AEB output equal to exceeding intake, clearing breath sounds, and decreasing edema.
Nursing Interventions
  • Establish rapport
    • Rationale: To gain patient’s trust and cooperation
  • Monitor and record VS
    • Rationale: To obtain baseline data
  • Assess patient’s general condition
    • Rationale: To determine what approach to use in treatment
  • Monitor I&O every 4 hours
    • Rationale: I&O balance reflects fluid status
  • Weigh patient daily and compare to previous weights.
    • Rationale: Body weight is a sensitive indicator of fluid balance and an increase indicates fluid volume excess.
  • Auscultate breath sounds q 2hr and pm for the presence of crackles and monitor for frothy sputum production
    • Rationale: When increased pulmonary capillary hydrostatic pressure exceeds oncotic pressure, fluid moves within the alveolar septum and is evidenced by the auscultation of crackles. Frothy, pink-tinged sputum is an indicator that the client is developing pulmonary edema
  • Assess for presence of peripheral edema. Do not elevate legs if the client is dyspneic.
    • Rationale: Decreased systemic blood pressure to stimulation of aldosterone, which causes increased renal tubular absorption of sodium Low-sodium diet helps prevent increased sodium retention, which decreases water retention. Fluid restriction may be used to decrease fluid intake, hence decreasing fluid volume excess.
  • Follow low-sodium diet and/or fluid restriction
    • Rationale: The client senses thirst because the body senses dehydration. Oral care can alleviate the sensation without an increase in fluid intake.
  • Encourage or provide oral care q2
    • Rationale: Heart failure causes venous congestion, resulting in increased capillary pressure. When hydrostatis pressure exceeds interstitial pressure, fluids leak out of ht ecpaillaries and present as edema in the legs, and sacrum. Elevation of legs increases venous return to the heart.

Acute Pain
Assessment

Patient may manifest the following

  • Difficulty of breathing
  • Chest pain
  • Restlessness
Diagnosis
  • Acute Pain
Planning & Desired Outcomes
  • Patient’s pain will be decreased.
  • Patient will demonstrate activities and behaviors that will prevent the recurrence of pain.
Nursing Interventions
  • Assess patient pain for intensity using a pain rating scale, for location and for precipitating factors.
    • Rationale: To identify intensity, precipitating factors and location to assist in accurate diagnosis.
  • Administer or assist with self-administration of vasodilators, as ordered.
    • Rationale: The vasodilator nitroglycerin enhances blood flow to the myocardium. It reduces the amount of blood returning to the heart, decreasing preload which in turn decreases the workload of the heart.
  • Assess the response to medications every 5 minutes
    • Rationale: Assessing response determines effectiveness of medication and whether further interventions are required.
  • Provide comfort measures.
    • Rationale: To provide nonpharmacological pain management.

  • Establish a quiet environment.
    • Rationale: A quiet environment reduces the energy demands on the patient.
  • Elevate head of bed.
    • Rationale: Elevation improves chest expansion and oxygenation.
  • Monitor vital signs, especially pulse and blood pressure, every 5 minutes until pain subsides.
    • Rationale: Tachycardia and elevated blood pressure usually occur with angina and reflect compensatory mechanisms secondary to sympathetic nervous system stimulation.
  • Provide oxygen and monitor oxygen saturation via pulse oximetry, as ordered.
    • Rationale: Oxygenation increases the amount of oxygen circulating in the blood and, therefore, increases the amount of available oxygen to the myocardium, decreasing myocardial ischemia and pain.
  • Assess results of cardiac markers—creatinine phosphokinase, CK- MB, total LDH, LDH-1, LDH-2, troponin, and myoglobin ordered by physician.
    • Rationale: These enzymes elevate in the presence of myocardial infarction at differing times and assist in ruling out a myocardial infarction as the cause of chest pain.
  • Assess cardiac and circulatory status.
    • Rationale: Assessment establishes a baseline and detects changes that may indicate a change in cardiac output or perfusion.
  • Monitor cardiac rhythms on patient monitor and results of 12 lead ECG.
    • Rationale: Notes abnormal tracings that would indicate ischemia.
  • Teach patient relaxation techniques and how to use them to reduce stress.
    • Rationale: Anginal pain is often precipitated by emotional stress that can be relieved non-pharmacological measures such as relaxation.
  • Teach the patient how to distinguish between angina pain and signs and symptoms of myocardial infarction.
    • Rationale: In some case, the chest pain may be more serious than stable angina. The patient needs to understand the differences in order to seek emergency care in a timely fashion.
