Reference: Ch. 1 — Heart Failure: Left Heart Failure (Anatomical
overview → Left heart failure)
Stem: A 68-year-old man with long-standing hypertension
presents with progressively worsening dyspnea on exertion and
orthopnea. On auscultation you hear bibasilar crackles; chest x-
ray shows pulmonary congestion. Which pathophysiologic
mechanism best explains his symptoms?
A. Right ventricular failure causing systemic venous congestion
and hepatomegaly
B. Left ventricular systolic dysfunction causing increased
pulmonary capillary hydrostatic pressure
C. Decreased systemic vascular resistance causing reflex
tachypnea
D. Mitral stenosis causing reduced left atrial pressure and
pulmonary underperfusion
,Correct Answer: B
Rationales:
• Correct (B): Left ventricular systolic dysfunction (or
impaired LV emptying) raises left ventricular end-diastolic
pressure, transmitted backward to left atrium and
pulmonary capillaries, increasing hydrostatic pressure and
causing pulmonary edema and dyspnea — classic left heart
failure physiology described by Berkowitz.
• A: Right ventricular failure causes systemic venous
congestion, not pulmonary crackles; it does not explain
pulmonary edema.
• C: Decreased systemic vascular resistance would not cause
pulmonary congestion and typically lowers afterload, not
produce the described chest findings.
• D: Mitral stenosis raises left atrial pressure (not reduces it)
and can cause pulmonary symptoms, but the scenario
(hypertension, LV dysfunction, bibasilar crackles) fits LV
systolic failure better.
Teaching Point: Left ventricular failure produces pulmonary
edema by increasing pulmonary capillary hydrostatic pressure.

Reference: Ch. 1 — Heart Failure: Right Heart Failure
,(Symptoms and signs of heart failure)
Stem: A patient with chronic COPD now has new peripheral
edema, jugular venous distention, and hepatomegaly. Which
nursing assessment finding most directly supports the diagnosis
of right heart failure?
A. Fine inspiratory crackles at lung bases
B. Elevated jugular venous pressure that increases with
abdominal compression
C. Loud S1 with an S4 gallop
D. Warm, well-perfused extremities with bounding pulses
Correct Answer: B
Rationales:
• Correct (B): Elevated JVP that rises with abdominal
compression (positive hepatojugular reflux) indicates
systemic venous congestion due to right ventricular failure
— a bedside sign emphasized in Berkowitz.
• A: Fine inspiratory crackles point to pulmonary congestion
from left heart failure rather than isolated right heart
failure.
• C: S4 suggests stiff left ventricle/diastolic dysfunction, not
a specific sign of right heart failure.
• D: Warm, bounding pulses are more consistent with high-
output states or aortic regurgitation; right heart failure
typically has cool extremities from reduced forward flow.
, Teaching Point: Hepatojugular reflux and elevated JVP are key
signs of right-sided failure.

Reference: Ch. 1 — Preload, Afterload, and Treatment of Heart
Failure
Stem: A patient with acute decompensated heart failure is
short of breath and hypertensive. Which immediate medication
choice most directly reduces preload and improves pulmonary
edema?
A. Intravenous loop diuretic (e.g., furosemide)
B. Beta-blocker bolus
C. Phenylephrine infusion
D. IV fluids bolus of normal saline
Correct Answer: A
Rationales:
• Correct (A): Loop diuretics reduce intravascular volume →
lower preload → decrease pulmonary capillary hydrostatic
pressure and relieve pulmonary edema. This is first-line for
acute volume overload per Berkowitz’s preload/afterload
discussion.
• B: Beta-blockers are beneficial chronically but can acutely
worsen decompensation if given as bolus in unstable HF.
