Pathophysiology: Understanding Disease Processes
Cellular adaptation, system-specific disorders, and clinical pathophysiology
Q1: A 68-year-old patient with chronic hypertension presents with left ventricular
hypertrophy. This cellular adaptation represents:
A. Atrophy due to decreased workload — this describes disuse, not increased demand
B. Hyperplasia from hormonal stimulation — this involves cell number increase, not size
C. Hypertrophy from increased mechanical demand — this correctly describes the
adaptive thickening of cardiac muscle [CORRECT]
D. Metaplasia from chronic irritation — this is tissue type change, not muscle
enlargement
,Correct Answer: C
Rationale: Hypertrophy is the increase in cell size (not number) in response to increased
workload. The heart muscle thickens to compensate for chronic pressure overload in
hypertension. Option A describes size decrease, B describes cell number increase, and
D describes tissue transformation.
Q2: During the inflammatory response, which vascular change occurs first?
A. Leukocyte migration — this occurs after vascular changes
B. Vasodilation and increased vascular permeability — this correctly describes the initial
vascular phase [CORRECT]
C. Phagocytosis by macrophages — this is a later cellular event
D. Collagen deposition — this occurs during repair, not acute inflammation
Correct Answer: B
Rationale: The vascular phase of acute inflammation begins immediately with
vasodilation (redness, heat) and increased permeability (edema), followed by cellular
events. Option A follows vascular changes, C is later, and D is repair phase.
Q3: A patient with severe vomiting has the following arterial blood gas: pH 7.48, PaCO₂
48 mmHg, HCO₃⁻ 35 mEq/L. This represents:
,A. Respiratory acidosis — this would show low pH with high PaCO₂
B. Metabolic acidosis — this would show low pH with low HCO₃⁻
C. Metabolic alkalosis — this correctly shows elevated pH with elevated HCO₃⁻
[CORRECT]
D. Respiratory alkalosis — this would show elevated pH with low PaCO₂
Correct Answer: C
Rationale: The elevated pH (alkalemia) with elevated HCO₃⁻ (metabolic component) and
compensatory elevated PaCO₂ indicates metabolic alkalosis from vomiting (acid loss).
Option A is acidotic, B is acidotic, and D has low PaCO₂.
Q4: In the pathophysiology of atherosclerosis, fatty streaks represent:
A. Calcified plaque with fibrous cap — this describes complicated lesions
B. Early lesions with lipid-laden foam cells — this correctly describes initial atheroma
formation [CORRECT]
C. Organized thrombus — this describes thrombotic occlusion
D. Vasospastic narrowing — this describes Prinzmetal's angina mechanism
Correct Answer: B
, Rationale: Fatty streaks are the earliest visible lesions, consisting of lipid-laden
macrophages (foam cells) in the intima. Option A describes advanced plaques, C
describes thrombosis, and D describes functional narrowing.
Q5: A patient with chronic obstructive pulmonary disease (COPD) develops cor
pulmonale. The primary pathophysiological mechanism is:
A. Left ventricular failure backing up into lungs — this describes left heart failure
B. Pulmonary hypertension increasing right ventricular afterload — this correctly
describes the pressure overload on the right heart [CORRECT]
C. Viral infection of myocardium — this describes myocarditis
D. Coronary artery occlusion — this describes ischemic heart disease
Correct Answer: B
Rationale: Cor pulmonale is right heart failure secondary to pulmonary disease. COPD
causes pulmonary hypertension (hypoxic vasoconstriction, vascular remodeling),
increasing right ventricular workload. Option A is left failure, C is infectious, and D is
coronary disease.
Q6: Which cellular process is characteristic of irreversible cell injury?
A. Cellular swelling — this occurs in reversible injury
