Heart Failure, Pulmonary Edema: Priority Actions - NCLEX Rn

1. A 69-year-old post-operative client (abdominal surgery 2 days ago) with a history of heart failure is receiving intravenous maintenance fluids at 125 mL/hr. The client now reports shortness of breath and has frothy sputum. Assessment: respiratory rate 32/min, oxygen saturation 86% on 4 L/min nasal cannula, heart rate 116/min, blood pressure 162/94 mm Hg, crackles throughout, and jugular venous distention. Which intervention should the nurse implement IMMEDIATELY?
   Answer: Stop the intravenous fluids and keep the vein open with a saline lock per facility protocol This client has acute pulmonary edema from rapid fluid overload — frothy sputum, hypoxia, crackles, tachypnea, and JVD all point to it — and the IV maintenance fluid is the source. Stopping the intravenous fluids and keeping the vein open with a saline lock is the immediate priority because it removes the cause of the respiratory compromise while preserving IV access for treatment. Obtaining a B-type natriuretic peptide level only delays action: the clinical picture already establishes fluid overload, and a lab result will not remove the fluid. Encouraging coughing and deep breathing targets secretions, but this is alveolar fluid from heart failure, not mucus plugging, and the effort can worsen hypoxemia. Delegating antiembolism stockings addresses DVT prophylaxis, which is unrelated to this acute crisis. The transferable principle: in a client with heart failure, signs of pulmonary edema during an IV infusion mean stop the fluid source first — before diagnostics, comfort measures, or routine prophylaxis.
2. A 66-year-old client with heart failure is receiving intravenous furosemide for pulmonary edema on a step-down unit. Thirty minutes after administration, the client reports dizziness and worsening weakness. Assessment: blood pressure 88/54 mm Hg (was 142/86), heart rate 118/min, respiratory rate 24/min, oxygen saturation 92% on 4 L/min nasal cannula; lung sounds improved from crackles to mild bibasilar crackles. Which assessment finding requires the nurse to act FIRST?
   Answer: Blood pressure 88/54 mm Hg with new dizziness This question tests prioritization and clinical judgment in recognizing and managing diuretic-induced hypotension. The priority framework is ABCs, specifically addressing circulation compromise that threatens organ perfusion. The blood pressure of 88/54 mm Hg with new dizziness (Option A) requires immediate action because it indicates significant hypotension that could lead to inadequate organ perfusion, falls, or shock. The oxygen saturation of 92% (Option B) is acceptable on supplemental oxygen; tachycardia (Option C) is expected with hypotension as a compensatory mechanism; mild bibasilar crackles (Option D) show improvement from the diuretic. The decision-making principle is that while diuretics effectively treat pulmonary edema, they can cause dangerous hypotension requiring immediate intervention to prevent complications. The transferable strategy is: monitor blood pressure closely after diuretic administration, and prioritize treating symptomatic hypotension over other expected findings.
3. A 60-year-old client with a history of heart failure is in the emergency department with acute pulmonary edema. Assessment: respiratory rate 34/min, oxygen saturation 82% on room air, heart rate 126/min, blood pressure 188/108 mm Hg, and crackles throughout. Which intervention should the nurse implement IMMEDIATELY?
   Answer: Position the client upright and begin high-flow oxygen while preparing for noninvasive ventilation In acute pulmonary edema, the earliest threat is severe hypoxemia. This client has tachypnea, crackles throughout, and an SpO2 of 82% on room air, so the priority is to support oxygenation and ventilation. Positioning the client upright and begin high-flow oxygen while preparing for noninvasive ventilation directly addresses the ABC priority and reduces the risk of respiratory failure. The other actions can wait. Obtaining a urine sample for specific gravity before a prescribed IV diuretic is diagnostic and should not delay urgent treatment. Completing admission documentation and performing medication reconciliation, even while the client is receiving high-flow oxygen, does not treat the current respiratory distress. Delegating height and weight measurement to assistive personnel collects baseline data but is not an immediate life-sustaining intervention. The correct action is therefore the upright position with high-flow oxygen while also preparing for noninvasive ventilation.
4. A 64-year-old client arrives in the emergency department with a history of heart failure and reports sudden severe shortness of breath that started 30 minutes ago while lying down to sleep. Assessment: anxious, speaking in one-word sentences; respiratory rate 36/min; oxygen saturation 78% on nonrebreather mask at 15 L/min; heart rate 132/min; blood pressure 204/110 mm Hg; crackles throughout both lungs; skin cool and diaphoretic. What is the nurse's PRIORITY action for this client?
   Answer: Prepare for noninvasive positive-pressure ventilation and notify respiratory therapy This question tests prioritization and clinical judgment in managing severe acute pulmonary edema with impending respiratory failure. The priority framework is ABCs, specifically addressing imminent respiratory failure despite maximal oxygen therapy. Preparing for noninvasive positive-pressure ventilation and notifying respiratory therapy (Option B) is the highest priority because the client shows signs of respiratory failure (SpO2 78% on 15L nonrebreather, one-word sentences, RR 36) requiring immediate ventilatory support. Inserting a urinary catheter (Option A) can wait and won't address the respiratory crisis; obtaining medication history (Option C) is important but secondary to stabilizing breathing; requesting a chest X-ray (Option D) delays critical intervention. The decision-making principle is that when maximal oxygen therapy fails to maintain adequate oxygenation in acute pulmonary edema, immediate ventilatory support is required to prevent intubation. The transferable strategy is: recognize that hypoxia unresponsive to high-flow oxygen with severe respiratory distress indicates the need for immediate advanced respiratory support.
5. A 70-year-old client with heart failure is admitted with shortness of breath and edema. Current findings: blood pressure 146/84 mm Hg, heart rate 106/min, respiratory rate 24/min, oxygen saturation 91% on room air, crackles at bases, and urine output 35 mL/hr. Which intervention should the nurse implement IMMEDIATELY?
   Answer: Place the client in semi-Fowler position and apply supplemental oxygen as needed This question tests prioritization and clinical judgment in managing admission symptoms of heart failure with edema and dyspnea. It uses the ABC framework to address mild respiratory compromise. Placing the client in semi-Fowler position and applying supplemental oxygen as needed is the immediate action because it improves saturation (91%) and crackles, supporting breathing. Teaching weights (B) and diet (C) are educational; measuring girth (D) monitors. The principle is to optimize positioning for pulmonary congestion. This meets basic needs. For similar admissions, prioritize comfort and oxygenation before teaching or monitoring.
6. A 72-year-old client with heart failure is receiving oxygen at 2 L nasal cannula and has crackles at the bases. The client suddenly becomes cyanotic and cannot speak full sentences. Assessment: respiratory rate 38/min, oxygen saturation 79%, heart rate 140/min, blood pressure 184/108 mm Hg. What is the nurse's PRIORITY action for this client?
   Answer: Apply a nonrebreather mask and call for rapid response/advanced assistance This question tests prioritization and clinical judgment in managing sudden cyanosis and distress in heart failure with baseline crackles. It employs the ABC framework for escalating respiratory failure. Applying a nonrebreather mask and calling for rapid response/advanced assistance is the priority because it addresses severe hypoxemia (79%) and inability to speak, preventing arrest. Obtaining labs (B) diagnoses; administering diuretic (C) delays; teaching (D) is inappropriate. The principle is to escalate support in flash decompensation. This aligns with emergency protocols. A transferable strategy is to activate teams for acute color and speech changes.
7. A 79-year-old client with heart failure in a long-term care facility has gradually worsening edema and fatigue. Today the client is more short of breath when speaking. Assessment: blood pressure 150/88 mm Hg, heart rate 102/min, respiratory rate 26/min, oxygen saturation 89% on room air, crackles at bases, and weight gain of 2.3 kg in 5 days. What is the nurse's PRIORITY action for this client?
   Answer: Apply supplemental oxygen and place the client in high-Fowler position This question tests prioritization and clinical judgment in managing gradual worsening in chronic heart failure in long-term care. It applies the ABC framework to emerging respiratory symptoms. Applying supplemental oxygen and placing the client in high-Fowler position is the priority because it improves hypoxemia (89%), crackles, and dyspnea, preventing acute decline. Teaching leg elevation (B) addresses edema; dietary recall (C) investigates causes; scheduling appointment (D) delays. The principle is to stabilize breathing in insidious exacerbations. This focuses on physiological needs. A transferable strategy is to prioritize oxygenation for subtle respiratory changes in elderly clients.
8. A 61-year-old client with heart failure is on a medical unit receiving oxygen at 2 L/min nasal cannula. After returning from the bathroom, the client becomes acutely short of breath. Assessment: respiratory rate 30/min, oxygen saturation 85%, heart rate 120/min, blood pressure 170/98 mm Hg, and new crackles in all lung fields; the client is coughing up pink-tinged sputum. What is the nurse's PRIORITY action for this client?
   Answer: Increase oxygen delivery and place the client in an upright position This question tests prioritization and clinical judgment in managing acute pulmonary edema with pink-tinged sputum. The priority framework is ABCs, addressing the immediate threat to breathing from severe pulmonary congestion. Increasing oxygen delivery and placing the client in an upright position (Option A) is the highest priority because it immediately addresses the critical hypoxia (SpO2 85%) and helps reduce pulmonary congestion while the pink-tinged sputum indicates severe pulmonary edema requiring urgent intervention. Notifying the provider for chest X-ray (Option B) delays immediate treatment; assessing edema and weight (Option C) is important but not urgent; delegating vital signs (Option D) doesn't address the crisis. The decision-making principle is that pink-tinged or frothy sputum with severe hypoxia indicates life-threatening pulmonary edema requiring immediate respiratory support. The transferable strategy is: recognize pink/frothy sputum as a critical sign requiring immediate oxygenation and positioning interventions.
9. A 63-year-old client with heart failure is receiving intravenous diuretics. Morning labs: potassium 2.9 mEq/L (low; normal 3.5–5.0 mEq/L), magnesium 1.5 mg/dL (low; normal 1.7–2.2 mg/dL). Current assessment: heart rate 112/min with occasional premature ventricular contractions on telemetry, oxygen saturation 94% on 2 L nasal cannula. Which assessment finding requires the nurse to act FIRST?
   Answer: Potassium 2.9 mEq/L with ventricular ectopy on telemetry This question tests prioritization and clinical judgment in monitoring diuretic therapy in heart failure. It uses safety principles to identify electrolyte imbalances posing arrhythmia risks. Potassium 2.9 mEq/L with ventricular ectopy on telemetry requires action first because hypokalemia exacerbates dysrhythmias, risking cardiac instability. Magnesium 1.5 mg/dL (B) is low but without symptoms; saturation 94% (C) is stable; heart rate 112/min (D) is compensatory. The principle is to address electrolyte-induced ectopy promptly to prevent ventricular tachycardia. This aligns with ABC circulation priorities. For similar situations, triage lab abnormalities with clinical correlates like ectopy highest.
10. A 69-year-old client with heart failure is on intravenous furosemide for pulmonary edema. Current data: urine output 20 mL/hr for 2 hours, blood pressure 98/60 mm Hg, heart rate 108/min, respiratory rate 24/min, oxygen saturation 92% on 4 L nasal cannula, and creatinine 2.1 mg/dL (elevated; prior 1.2 mg/dL). What is the nurse's PRIORITY action for this client?
    Answer: Assess perfusion and notify the provider of hypotension, low urine output, and rising creatinine This question tests prioritization and clinical judgment in managing complications of diuretic therapy in heart failure with pulmonary edema. It applies the ABC framework, shifting focus to circulation amid signs of hypoperfusion. Assessing perfusion and notifying the provider of hypotension, low urine output, and rising creatinine is the priority because it addresses potential acute kidney injury from overdiuresis, preventing further compromise. Continuing infusion (A) ignores risks; encouraging fluids (C) may not be appropriate; obtaining weight (D) is monitoring. The principle is to balance diuresis with perfusion, monitoring for dehydration. This ensures safety in fluid management. For similar cases, prioritize renal perfusion indicators when diuresing aggressively.
11. A 79-year-old client in a long-term care facility has chronic heart failure and has had gradually worsening fatigue and swelling over 2 weeks. Today the client is more short of breath at rest. Assessment: respiratory rate 30/min, oxygen saturation 89% on room air, heart rate 104/min, blood pressure 146/84 mm Hg, bilateral crackles halfway up the lungs, 3+ pitting edema, and weight gain of 3.2 kg (7 lb) in 10 days. Which intervention should the nurse implement IMMEDIATELY?
    Answer: Start oxygen therapy and position the client upright to improve ventilation This question tests prioritization and clinical judgment in managing decompensated heart failure with respiratory compromise. The priority framework is ABCs, focusing on the immediate breathing threat from pulmonary congestion. Starting oxygen therapy and positioning the client upright (Option B) is the highest priority because it directly addresses the hypoxia (SpO2 89%) and tachypnea while helping reduce pulmonary congestion through gravity-assisted venous pooling. Reviewing missed diuretics (Option A) is important for understanding the cause but doesn't provide immediate relief; teaching (Option C) is inappropriate during acute distress; delegating calf measurements (Option D) addresses assessment but not the urgent respiratory compromise. The decision-making principle is that gradual worsening of heart failure symptoms culminating in respiratory distress requires immediate intervention to prevent further decompensation. The transferable strategy is: in chronic heart failure exacerbations with respiratory compromise, always address oxygenation and positioning first, then investigate causes and implement medical management.
12. A 74-year-old client with heart failure is admitted with pulmonary edema and is anxious and restless. Assessment: oxygen saturation 81% on room air, respiratory rate 34/min, heart rate 130/min, blood pressure 182/104 mm Hg, crackles throughout, and audible gurgling respirations. What is the nurse's PRIORITY action for this client?
    Answer: Position the client upright and apply high-flow oxygen while preparing suction equipment. Airway and oxygenation are the immediate priorities. This client has audible gurgling respirations, widespread crackles, and an oxygen saturation of 81%, so the nurse must first position him upright to improve ventilation, deliver high-flow oxygen to correct hypoxemia, and have suction ready in case secretions obstruct the airway. The anti-anxiety medication may reduce distress but does not clear the airway or improve oxygenation, and sedation can depress respirations. Performing a focused cardiac assessment and medication reconciliation is useful later, but it delays the critical intervention while the client is in acute respiratory distress. Obtaining a urine specimen may be needed before diuretic therapy, but it is not the priority when airway and breathing are threatened. Only the airway/oxygenation intervention directly addresses the life-threatening findings.
13. A 69-year-old client with heart failure is receiving intravenous morphine for severe dyspnea related to pulmonary edema per provider order. Ten minutes later: respiratory rate 10/min, oxygen saturation 88% on 4 L nasal cannula, client difficult to arouse. What is the nurse's PRIORITY action for this client?
    Answer: Administer naloxone per protocol and support ventilation as needed This question tests prioritization and clinical judgment in managing opioid-induced respiratory depression in heart failure with pulmonary edema. It applies the ABC framework, emphasizing airway and breathing reversal. Administering naloxone per protocol and supporting ventilation as needed is the priority because it counters morphine's effects causing low rate (10/min) and arousability issues. Reassuring family (B) minimizes urgency; pain scoring (C) continues opioids; delegating vitals (D) delays. The principle is to reverse oversedation promptly in dyspneic clients. This ensures safety from medication adverse effects. A transferable strategy is to monitor and intervene quickly on respiratory changes post-opioid.
14. A 62-year-old client with known heart failure presents to the emergency department after missing diuretics for 3 days. Assessment: blood pressure 174/100 mm Hg, heart rate 122/min, respiratory rate 30/min, oxygen saturation 86% on room air, crackles to the apices, and bilateral 2+ edema. Which intervention should the nurse implement IMMEDIATELY?
    Answer: Apply supplemental oxygen and position the client upright to improve ventilation This question tests prioritization and clinical judgment in managing acute exacerbation of heart failure due to medication nonadherence. It utilizes the ABC priority framework to address impaired breathing and oxygenation. Applying supplemental oxygen and positioning the client upright to improve ventilation is the immediate action because it tackles hypoxemia (86%), crackles, and dyspnea directly. Medication teaching (B) and history (C) are educational; administering furosemide (D) requires order and delays ABCs. The principle is to stabilize acute symptoms before addressing causes like missed diuretics. This follows Maslow's physiological needs. A transferable strategy is to prioritize oxygenation in nonadherent clients presenting with decompensation.
15. A 71-year-old client with chronic heart failure in a skilled nursing facility reports needing to sleep on three pillows and waking up gasping for air. Assessment: respiratory rate 24/min, oxygen saturation 90% on room air, heart rate 104/min, blood pressure 142/86 mm Hg, crackles at bases, and 2+ ankle edema. What is the nurse's PRIORITY action for this client?
    Answer: Place the client in high-Fowler position and apply supplemental oxygen per facility protocol This question tests prioritization and clinical judgment in managing orthopnea in chronic heart failure in a skilled nursing facility. It uses the ABC framework, focusing on breathing difficulties indicated by symptoms. Placing the client in high-Fowler position and applying supplemental oxygen per facility protocol is the priority because it alleviates orthopnea, crackles, and low saturation (90%), improving gas exchange. Scheduling physical therapy (B) and teaching (C) are rehabilitative; delegating weights (D) is monitoring. The principle is to address paroxysmal nocturnal dyspnea immediately to prevent escalation. This prioritizes physiological stability. For similar situations, intervene on positioning and oxygen before long-term planning.
16. A 68-year-old postoperative day 1 client after hip repair has a history of heart failure with reduced ejection fraction and received 2 L of intravenous fluids overnight for hypotension. Current findings: blood pressure 148/86 mm Hg, heart rate 112/min, respiratory rate 28/min, oxygen saturation 88% on 2 L nasal cannula, new crackles at bases, and jugular venous distention. What is the nurse's PRIORITY action for this client?
    Answer: Increase oxygen delivery and raise the head of the bed, then notify the provider of suspected fluid overload This client has acute respiratory compromise from fluid overload: SpO2 88%, crackles, JVD, tachycardia, and tachypnea after aggressive IV fluids in a setting of reduced ejection fraction. The priority is to relieve hypoxemia and reduce cardiac workload. Raising the head of the bed and increasing oxygen delivery directly address breathing and circulation; notifying the provider of suspected fluid overload starts treatment of the cause. Encouraging oral fluids is harmful because it adds volume to an already overloaded circulation and can worsen pulmonary edema. Obtaining a pain assessment and giving an opioid are not indicated: there are no pain indicators, and opioids can blunt respiratory drive. Requesting dietary teaching is a reasonable long-term measure, not an immediate action during acute decompensation. The correct choice uses the ABC framework and recognizes iatrogenic volume overload before pulmonary edema progresses.
17. A 65-year-old client with heart failure is admitted for pulmonary edema. Current assessment: oxygen saturation 88% on 4 L nasal cannula, respiratory rate 30/min, blood pressure 152/90 mm Hg, heart rate 116/min, and crackles to mid-lung fields. The provider gives several orders. The nurse should QUESTION which order given the client's condition?
    Answer: Give a 1-liter bolus of lactated Ringer solution for perfusion support This question tests prioritization and clinical judgment in evaluating orders for pulmonary edema in heart failure. It uses safety principles to identify harmful interventions. Giving a 1-liter bolus of lactated Ringer solution for perfusion support should be questioned because it worsens overload with low saturation (88%) and crackles, risking deterioration. Administering furosemide (A) aids diuresis; monitoring I/O (B) tracks; NIPPV (D) supports breathing. The principle is to avoid volume expansion in edematous states. This promotes advocacy. For similar orders, question fluid boluses in volume-overloaded conditions.
18. A 75-year-old client with heart failure is admitted for fluid overload. The provider writes new orders. Current assessment: respiratory rate 28/min, oxygen saturation 87% on 2 L nasal cannula, crackles to mid-lung fields, blood pressure 156/88 mm Hg. The nurse should QUESTION which order given the client's condition?
    Answer: Infuse 0.9% sodium chloride 1,000 mL bolus over 1 hour This question tests prioritization and clinical judgment in evaluating provider orders for a client with heart failure and fluid overload. It employs safety principles to identify inappropriate interventions that could worsen the condition. Infusing 0.9% sodium chloride 1,000 mL bolus over 1 hour should be questioned because it exacerbates fluid overload amid crackles and low saturation (87%), risking further pulmonary edema. Administering furosemide (A) promotes diuresis; restricting fluids (B) reduces intake; applying oxygen (D) supports breathing. The decision-making principle is to challenge orders contradicting the client's volume status. This aligns with nursing advocacy for patient safety. A transferable strategy is to question volume-expanding orders in overloaded heart failure clients.
19. A 70-year-old client with chronic heart failure is admitted for worsening dyspnea and is now acutely anxious with increased work of breathing. Findings: blood pressure 158/92 mm Hg, heart rate 118/min, respiratory rate 30/min, oxygen saturation 85% on 4 L nasal cannula, crackles to mid-lung fields, and cool clammy skin. Which intervention should the nurse implement IMMEDIATELY?
    Answer: Switch to a nonrebreather mask and position the client upright This question tests prioritization and clinical judgment in managing acute anxiety and dyspnea in a client with chronic heart failure. It utilizes the ABC priority framework to address hypoxemia and increased work of breathing. Switching to a nonrebreather mask and positioning the client upright is the immediate intervention because it optimizes oxygenation (85% saturation) and reduces preload amid crackles and clammy skin. Calling for nebulizer (A) assumes wheezing without mention; anxiety rating and breathing techniques (C) are secondary to oxygenation; delegating weight and output (D) is monitoring, not acute. The principle is to correct hypoxemia first, as it exacerbates anxiety and distress. This follows Maslow's by meeting basic physiological needs. A transferable strategy is to escalate oxygen delivery and positioning before other interventions in decompensating heart failure.
20. A 67-year-old client with heart failure is receiving oxygen at 6 L/min by nasal cannula. The client becomes increasingly dyspneic after returning from radiology. Assessment: respiratory rate 32/min, oxygen saturation 83%, heart rate 126/min, blood pressure 170/96 mm Hg, and crackles throughout. Which intervention should the nurse implement IMMEDIATELY?
    Answer: Increase oxygen delivery by switching to a nonrebreather mask and position upright This question tests prioritization and clinical judgment in managing worsening dyspnea post-activity in a client with heart failure. It applies the ABC framework to correct acute hypoxemia. Increasing oxygen delivery by switching to a nonrebreather mask and positioning upright is the immediate action because it addresses dropping saturation (83%) and crackles, enhancing ventilation. Obtaining BNP (B) is diagnostic; documenting and rechecking (C) delays; delegating water (D) is irrelevant. The principle is to escalate oxygen for transport-induced decompensation. This ensures safety during transitions. A transferable strategy is to prioritize oxygen modality changes in acute desaturation events.
