Reference: Ch. 1 — Anatomical Overview: Cardiac chambers &
circulation
Question stem: A 68-year-old man with chronic ischemic heart
disease has sudden jugular venous distention, hypotension, and
muffled heart sounds after an inferior MI. Which anatomic
change best explains his clinical triad?
A. Acute left ventricular free wall rupture causing
hemopericardium
B. Right ventricular infarction with acute tricuspid regurgitation
,C. Rapid pericardial effusion producing cardiac tamponade
D. Papillary muscle rupture causing acute mitral regurgitation
Correct answer: C
Rationales
• Correct (C): Rapid accumulation of fluid in the pericardial
space increases intrapericardial pressure, limits ventricular
filling, and produces hypotension, JVD, and muffled heart
sounds (Beck’s triad). This aligns with the role of the
pericardial sac described by Berkowitz.
• A: Free wall rupture can cause hemopericardium, but the
abrupt catastrophic presentation often leads to sudden
death; tamponade physiology is possible but C is a clearer
explanation of the triad in a survivable presentation.
• B: Right ventricular infarction causes hypotension and JVD
but typically not muffled heart sounds from pericardial
pressure.
• D: Papillary muscle rupture causes pulmonary edema and
murmur from acute MR rather than muffled heart sounds
and tamponade physiology.
Teaching point: Rapid pericardial fluid impairs diastolic filling →
tamponade (Beck’s triad).

(pathophysiology & symptoms)
Question stem: A patient with chronic hypertension presents
with exertional dyspnea and bibasilar crackles. Which
pathophysiologic mechanism most likely produced his
pulmonary edema?
A. Increased pulmonary vascular permeability from
inflammation
B. Elevated left atrial pressure causing increased pulmonary
capillary hydrostatic pressure
C. Decreased oncotic pressure from hypoalbuminemia
D. Left-to-right intracardiac shunt increasing pulmonary blood
flow
Correct answer: B
Rationales
• Correct (B): In left heart failure the failing left ventricle
raises left atrial and pulmonary venous pressures,
increasing pulmonary capillary hydrostatic pressure and
causing transudation of fluid into alveoli (pulmonary
edema).
• A: Increased permeability causes ARDS-type edema, not
the cardiogenic pulmonary edema typical of left HF.
, • C: Hypoalbuminemia causes generalized edema, but not
the exertional pulmonary interstitial/alveolar edema linked
to elevated hydrostatic pressures.
• D: Left-to-right shunts cause pulmonary overcirculation
over time but are less likely the immediate cause in an
adult hypertensive patient.
Teaching point: Left ventricular failure → ↑pulmonary venous
pressure → cardiogenic pulmonary edema.

Reference: Ch. 1 — Heart Failure: Right Heart Failure (signs and
causes)
Question stem: A patient with chronic left heart failure
develops progressive peripheral edema, hepatomegaly, and
ascites. Which mechanism best explains these systemic venous
congestive signs?
A. Elevated systemic capillary oncotic pressure from liver failure
B. Right ventricular failure causing increased systemic venous
hydrostatic pressure
C. Hypoalbuminemia secondary to renal losses
D. Portal vein thrombosis causing localized congestion
Correct answer: B
