Q1
Reference: Ch. 1 — Preload, Afterload, and Treatment of Heart
Failure (Preload/Afterload concepts)
Question stem: A 72-year-old man with chronic systolic heart
failure (EF 30%) reports increasing dyspnea and orthopnea. His
BP is 140/78 mm Hg and weight has risen 4 kg in 2 weeks.
Which initial nursing intervention most directly reduces preload
and improves pulmonary congestion?
A. Start an ACE inhibitor (lisinopril) and monitor BP.
B. Administer a loop diuretic (IV furosemide) as ordered.
C. Give a beta-blocker (metoprolol) to reduce heart rate.
D. Start an arterial vasodilator (hydralazine) to reduce afterload.
Correct answer: B
Rationales:
, • Correct (B): Loop diuretics rapidly reduce intravascular
volume and venous return (preload), lowering left atrial
and pulmonary capillary pressures and improving
pulmonary edema and dyspnea — a primary acute
strategy in CHF exacerbation.
• A (ACE inhibitor): ACE inhibitors reduce afterload and
remodeling long-term but are not the fastest method to
relieve acute volume overload and pulmonary congestion.
• C (Beta-blocker): Beta-blockers improve long-term
outcomes but can worsen acute decompensation if
initiated or uptitrated during volume overload.
• D (Hydralazine): Arterial vasodilators primarily lower
afterload; they don’t promptly remove excess intravascular
volume to relieve pulmonary edema.
Teaching point: Loop diuretics rapidly lower preload and relieve
pulmonary congestion in acute heart-failure exacerbations.

Q2
Reference: Ch. 1 — Left Heart Failure (Signs & Symptoms)
Question stem: A patient with left-sided heart failure develops
sudden nocturnal dyspnea, pink frothy sputum, and bilateral
,crackles. Which nursing action is highest priority to improve
oxygenation?
A. Place the patient in high-Fowler’s position and give
supplemental oxygen.
B. Administer oral digoxin to improve contractility.
C. Encourage bed rest and obtain a BNP level.
D. Prepare for immediate bronchodilator nebulization.
Correct answer: A
Rationales:
• Correct (A): High-Fowler’s decreases venous return and
improves diaphragmatic excursion; combined with
supplemental oxygen, it immediately improves
oxygenation in pulmonary edema from left heart failure.
• B (Digoxin): Digoxin may help chronic systolic dysfunction
but is not an immediate rescue therapy for acute
pulmonary edema.
• C (BNP): BNP is useful diagnostically but obtaining it is not
the priority over immediate oxygenation support.
• D (Bronchodilator): Bronchodilators address
bronchospasm, not alveolar pulmonary edema due to
increased hydrostatic pressure.
Teaching point: In pulmonary edema from left HF, position and
oxygenation are immediate priorities.

Q3
Reference: Ch. 1 — Right Heart Failure (Signs & Mechanism)
Question stem: A patient with chronic pulmonary hypertension
presents with jugular venous distention, hepatomegaly, and
pitting peripheral edema. Which pathophysiologic explanation
best accounts for these findings?
A. Left ventricular systolic dysfunction causing increased
pulmonary venous pressure.
B. Right ventricular failure causing elevated systemic venous
pressure.
C. Mitral stenosis leading to systemic venous congestion.
D. Decreased plasma oncotic pressure from hypoalbuminemia.
Correct answer: B
Rationales:
• Correct (B): RV failure leads to impaired forward flow into
the pulmonary circulation, causing backlog into systemic
veins — producing JVD, hepatic congestion, and peripheral
edema.
• A (LV dysfunction): LV failure produces pulmonary
congestion primarily, not systemic venous congestion with
