Answers
1. A patient presents with dyspnea, crackles at lung bases, and an S3 gallop. Which
pathophysiological mechanism best explains these findings?
A. Decreased systemic vascular resistance
B. Increased left ventricular end-diastolic pressure causing pulmonary congestion
C. Right-sided heart failure with peripheral edema
D. Decreased pulmonary vascular resistance
✔ CORRECT ANSWER: B. Increased left ventricular end-diastolic pressure causing pulmonary
congestion
📘 Rationale: Left ventricular failure increases LVEDP, causing back-pressure into the pulmonary vasculature, leading
to pulmonary congestion (crackles), dyspnea, and an S3 gallop from increased filling pressures.
2. Which of the following correctly describes the Frank-Starling mechanism?
A. As preload decreases, stroke volume increases
B. As preload increases, myocardial contractility and stroke volume increase up to a physiological limit
C. Afterload directly increases cardiac output
D. Heart rate is inversely proportional to stroke volume
✔ CORRECT ANSWER: B. As preload increases, myocardial contractility and stroke volume increase up
to a physiological limit
📘 Rationale: The Frank-Starling law states that increased ventricular filling (preload) stretches myocardial fibers,
increasing the force of contraction and stroke volume—up to a pathological threshold beyond which the heart fails.
3. A 58-year-old male with a history of hypertension develops concentric left ventricular
hypertrophy. What is the primary adaptive mechanism?
A. Volume overload causing sarcomere replication in series
B. Pressure overload causing sarcomere replication in parallel
C. Decreased afterload stimulating myocyte hyperplasia
D. Increased preload stimulating cardiac remodeling
✔ CORRECT ANSWER: B. Pressure overload causing sarcomere replication in parallel
📘 Rationale: Chronic pressure overload (e.g., hypertension, aortic stenosis) leads to sarcomere replication in parallel,
increasing wall thickness (concentric hypertrophy), which normalizes wall stress per Laplace's law.
4. Which pathophysiological change is most responsible for the decreased exercise tolerance in
patients with chronic obstructive pulmonary disease (COPD)?
A. Decreased airway resistance
B. Air trapping and dynamic hyperinflation limiting inspiratory capacity
C. Increased diffusing capacity
D. Decreased pulmonary vascular resistance
✔ CORRECT ANSWER: B. Air trapping and dynamic hyperinflation limiting inspiratory capacity
📘 Rationale: In COPD, expiratory airflow limitation causes air trapping and dynamic hyperinflation during exercise.
This flattens the diaphragm and reduces inspiratory capacity, contributing to dyspnea and exercise intolerance.
