Heart Failure, Pulmonary Edema: Priority Actions - NCLEX Rn

1. Which medication class is first-line to rapidly reduce fluid overload in acute pulmonary edema?

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

2. What is the priority reason for applying CPAP or BiPAP in acute cardiogenic pulmonary edema?

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

3. Which physical finding most specifically supports right-sided heart failure rather than pulmonary edema?

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

4. What is the priority reason nitrates are used in acute pulmonary edema with hypertension?

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

5. What is the priority action when a patient on IV diuretics develops new ventricular ectopy?

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

6. Which vital sign must be checked before giving nitroglycerin for pulmonary edema?

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

7. Which nursing action is priority when a heart failure patient has rapid weight gain and edema?

   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.

8. What is the priority action when a patient with HF has new confusion and SpO2 84% on room air?

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

9. Which bedside action best decreases venous return and work of breathing in pulmonary edema?

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

10. Which assessment finding most strongly indicates pulmonary edema rather than isolated HF fatigue?

    Pink, frothy sputum. This symptom results from alveolar fluid mixed with blood, distinguishing it as a hallmark of pulmonary congestion beyond mere fatigue.

11. Which assessment best evaluates response to therapy in pulmonary edema within minutes?

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

12. Which oxygen delivery escalation is most appropriate when SpO2 remains low on nasal cannula?

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

13. What is the priority action when a heart failure patient reports new orthopnea and has crackles?

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

14. Identify the contraindication to nitroglycerin in a patient with acute pulmonary edema.

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

15. What is the priority nursing action if a patient with pulmonary edema cannot maintain airway patency?

    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.

16. What is the priority patient instruction to reduce fluid retention in chronic heart failure?

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

17. What is the first priority nursing action for acute pulmonary edema with severe dyspnea?

    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.

18. Which laboratory value is the priority to monitor for dysrhythmia risk during aggressive diuresis?

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

19. Which finding indicates impending respiratory failure in pulmonary edema requiring urgent escalation?

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

20. Which symptom is the most concerning indicator of acute decompensated heart failure at night?

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

21. Which hemodynamic concept explains pulmonary edema in left-sided heart failure?

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

22. What is the priority focused respiratory assessment in suspected pulmonary edema?

    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.

23. What is the priority nursing action when pink frothy sputum and severe crackles suddenly appear?

    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.

24. What is the most important parameter to monitor after IV furosemide in acute pulmonary edema?

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

25. What is the priority daily monitoring intervention to trend fluid status in heart failure?

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