Q1.
In the setting of chronic hypertension, which adaptive cellular change is most likely to
occur in cardiomyocytes, and what is the primary molecular trigger?
A. Hyperplasia triggered by increased B. Hypertrophy triggered by
insulin-like growth factor-1 (IGF-1) signaling mechanotransduction pathways involving
angiotensin II and endothelin-1
C. Metaplasia triggered by chronic D. Dysplasia triggered by oxidative
inflammatory cytokine release stress-induced DNA damage
Correct: B - Hypertrophy triggered by mechanotransduction pathways involving
angiotensin II and endothelin-1
Rationale:Chronic pressure overload in hypertension induces cardiomyocyte hypertrophy, not
hyperplasia, as adult cardiomyocytes are terminally differentiated. The primary triggers are
mechanical stretch and neurohumoral factors like angiotensin II and endothelin-1, which
activate intracellular signaling pathways (e.g., MAPK, calcineurin). Hyperplasia (A) occurs in
tissues with mitotic capacity; metaplasia (C) is a reversible change from one adult cell type to
another; dysplasia (D) is a preneoplastic alteration. Thus, B is correct.
Q2.
A patient presents with metabolic alkalosis and a positive urine chloride test (urine Cl > 20
mEq/L). Which of the following is the most likely underlying mechanism?
A. Vomiting with loss of hydrochloric acid B. Primary hyperaldosteronism causing
increased renal H loss
C. Diuretic therapy with furosemide causing D. Severe potassium depletion due to
contraction alkalosis laxative abuse
Correct: B - Primary hyperaldosteronism causing increased renal H loss
Rationale:Urine chloride helps distinguish saline-responsive (urine Cl { < 20) from
saline-resistant (urine Cl > 20) metabolic alkalosis. Vomiting (A) and diuretics (C) typically
cause saline-responsive alkalosis with low urine chloride. Laxative abuse (D) also leads to
low urine chloride. Primary hyperaldosteronism (B) causes mineralocorticoid excess,
increasing renal H secretion and potassium wasting, resulting in saline-resistant metabolic
alkalosis with high urine chloride. Therefore, B is correct.

Q3.
Which of the following best explains the pathophysiology of type II (non-ST-elevation)
myocardial infarction, and how does it differ from type I?
A. Plaque rupture with superimposed B. Supply-demand mismatch due to
thrombosis; type II involves coronary conditions like tachycardia or hypotension;
vasospasm alone type I involves plaque rupture with
thrombosis
C. Coronary microembolization from D. Spontaneous coronary artery dissection;
infective endocarditis; type I involves in-situ type I involves atherosclerotic plaque
thrombosis erosion
Correct: B - Supply-demand mismatch due to conditions like tachycardia or hypotension;
type I involves plaque rupture with thrombosis
Rationale:Type II MI is defined by myocardial injury due to an imbalance between oxygen
supply and demand, often from tachycardia, hypotension, or anemia, without acute plaque
rupture. Type I MI is caused by atherosclerotic plaque rupture with thrombosis. Option A
incorrectly attributes vasospasm alone to type II; vasospasm can cause type II but is not the
sole mechanism. Option C describes embolic MI (type III or IV). Option D describes type II
(dissection) but not the primary mechanism. Thus, B is correct.
Q4.
In a patient with acute respiratory distress syndrome (ARDS), which of the following best
describes the role of the alveolar epithelium injury in the progression to fibrosis?
A. Type I pneumocyte necrosis leads to B. Type II pneumocyte proliferation and
reduced surfactant production, causing differentiation into type I cells restore the
alveolar collapse and subsequent fibrosis. alveolar barrier, but dysregulated repair
leads to fibroblast activation.
C. Injury to the alveolar capillary D. Alveolar macrophages release TGF-
endothelium causes alveolar edema, but upon epithelial injury, promoting
epithelial injury is not pivotal for fibrosis. myofibroblast differentiation and collagen
deposition.
Correct: B - Type II pneumocyte proliferation and differentiation into type I cells restore
the alveolar barrier, but dysregulated repair leads to fibroblast activation.
Rationale:In ARDS, injury to both alveolar epithelium and endothelium occurs. Type II
pneumocytes are progenitor cells that proliferate and differentiate into type I cells to restore
the barrier. However, if the injury is severe or repair is dysregulated, this process fails, leading
to fibroblast activation and fibrosis. Option A is incorrect because Type I pneumocytes do not
produce surfactant; Type II do. Option C underestimates the role of epithelial injury. Option D
is a plausible mechanism but less comprehensive than B, which captures the repair process
and its failure. Therefore, B is the best answer.
