Heart Failure, Pulmonary Edema: Priority Actions - NCLEX-RN

Initiate nonrebreather mask, then consider CPAP/BiPAP per order. Nonrebreather delivers higher oxygen concentrations, and positive pressure ventilation reduces preload in refractory hypoxemia.

Place in high Fowler position and apply supplemental oxygen. This intervention reduces venous return to alleviate pulmonary congestion and improves oxygenation to counteract hypoxemia in acute distress.

Assess breath sounds for crackles and measure oxygen saturation. Crackles indicate fluid in the alveoli, while oxygen saturation quantifies the degree of hypoxemia in respiratory compromise.

Apply oxygen immediately and reassess oxygenation. Hypoxemia likely causes the confusion, necessitating immediate oxygen to restore cerebral perfusion and reassessment to evaluate efficacy.

IV loop diuretic (for example, furosemide). Loop diuretics promote rapid fluid excretion from the kidneys, decreasing pulmonary vascular volume and congestion.

Reduce preload and afterload to improve pulmonary congestion. Nitrates cause vasodilation, which decreases cardiac workload and facilitates fluid redistribution from the lungs.

Blood pressure. Nitroglycerin induces vasodilation that can precipitate hypotension, requiring baseline assessment to ensure safety.

Hypotension. Nitroglycerin exacerbates low blood pressure, potentially leading to cardiogenic shock in vulnerable patients.

High Fowler position with legs dependent if tolerated. This position minimizes preload by gravity-assisted venous pooling and eases diaphragmatic excursion for better ventilation.

Activate rapid response and begin high-flow oxygen support. These signs signal acute decompensation, requiring rapid team intervention and high oxygen to stabilize respiratory status.

Increased pulmonary capillary hydrostatic pressure from LV failure. Left ventricular dysfunction elevates pressure, forcing fluid into the alveoli and causing edema.

Urine output. Monitoring urine output evaluates the diuretic's effectiveness in reducing fluid overload and pulmonary congestion.

Serum potassium. Aggressive diuresis with loop diuretics depletes potassium, heightening the risk for cardiac arrhythmias.

Check potassium level and notify the provider promptly. Ventricular ectopy often stems from hypokalemia induced by diuretics, necessitating prompt evaluation and intervention.

Improved SpO2 and decreased work of breathing. These indicators reflect rapid improvements in gas exchange and respiratory effort following therapeutic interventions.

Improve oxygenation and reduce preload by positive pressure. Positive pressure enhances alveolar recruitment and decreases venous return, alleviating hypoxemia and cardiac strain.

Decreasing level of consciousness with worsening hypoxemia. Altered consciousness with hypoxemia signifies decompensating respiratory function, demanding immediate advanced airway support.

Prepare for intubation and provide bag-mask ventilation as needed. Loss of airway patency in respiratory failure requires preparation for mechanical ventilation to ensure adequate oxygenation.

Jugular venous distention. Jugular venous distention reflects elevated right atrial pressure from backward failure, contrasting with left-sided pulmonary symptoms.

Daily weights using the same scale and time. Consistent daily weights provide an accurate measure of fluid balance changes, guiding heart failure management.

Assess for worsening fluid overload and notify the provider. Rapid weight gain and edema signal fluid retention, requiring assessment and provider notification to prevent decompensation.

Restrict sodium intake as prescribed. Limiting sodium reduces osmotic fluid retention, helping maintain euvolemia in heart failure patients.

Paroxysmal nocturnal dyspnea. This symptom arises from nocturnal fluid redistribution into the lungs, indicating worsening left ventricular function.

Sit upright, apply oxygen, and anticipate IV diuretic therapy. These measures immediately relieve orthopnea and hypoxemia, while diuresis targets underlying fluid overload.
