,Q1. A patient with chronic gastroesophageal reflux disease (GERD) undergoes
endoscopy, revealing replacement of the stratified squamous epithelium of the lower
esophagus with columnar epithelium. Which cellular adaptation has occurred?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Atrophy
Correct Answer: B. Metaplasia
Rationale: Metaplasia is the reversible replacement of one differentiated cell type with
another, often in response to chronic irritation. In GERD, the esophageal squamous
epithelium changes to columnar-like epithelium (Barrett's esophagus) to better withstand
acid exposure. Hyperplasia is increased cell number, dysplasia is abnormal cell growth,
and atrophy is decreased cell size.
Why Wrong:
A - Hyperplasia involves increased cell number without change in cell type.
C - Dysplasia refers to abnormal cell morphology, not replacement with a different
normal cell type.
D - Atrophy is a decrease in cell size, not a change in cell type.

Q2. In acute inflammation, which sequence of events is most directly responsible for
the early recruitment of neutrophils to the site of injury?
A. Arteriolar vasodilation -> increased hydrostatic pressure -> edema -> neutrophil
chemotaxis
B. Endothelial activation -> selectin-mediated rolling -> integrin-mediated adhesion ->
transmigration
C. Mast cell degranulation -> histamine release -> increased vascular permeability ->
neutrophil diapedesis
D. Complement activation -> MAC formation -> neutrophil lysis -> release of
chemotactic factors
Correct Answer: B. Endothelial activation -> selectin-mediated rolling ->
integrin-mediated adhesion -> transmigration
Rationale: Neutrophil recruitment follows a precise cascade: endothelial activation
induces selectin expression causing rolling, then integrin activation leads to firm
adhesion, followed by transmigration across the endothelium. This sequence is critical for
neutrophils to exit the bloodstream and reach tissues.
Why Wrong:
A - While vasodilation and edema occur, they do not directly cause neutrophil
chemotaxis; chemotactic factors guide migration.
Page 3
, C - Histamine increases permeability but does not orchestrate the multi-step adhesion
cascade; it facilitates leakage but not directed migration.
D - MAC formation causes cell lysis and is part of the complement defense, not the
primary mechanism for neutrophil recruitment.

Q3. Which mechanism best explains the development of pulmonary edema in a
patient with acute left ventricular failure?
A. Increased capillary filtration due to elevated hydrostatic pressure in the pulmonary
circulation
B. Decreased plasma oncotic pressure from hypoalbuminemia secondary to hepatic
congestion
C. Lymphatic obstruction due to distended pulmonary veins impeding drainage
D. Increased capillary permeability caused by ischemia of the alveolar-capillary
membrane
Correct Answer: A. Increased capillary filtration due to elevated hydrostatic pressure
in the pulmonary circulation
Rationale: Left ventricular failure reduces cardiac output, causing blood to back up into
the pulmonary veins. This elevates pulmonary capillary hydrostatic pressure, forcing fluid
into the interstitial space and alveoli (cardiogenic pulmonary edema). Options B, C, and D
are not primary mechanisms in acute left-sided failure.
Why Wrong:
B - Hypoalbuminemia is more common in liver failure or nephrotic syndrome, not
acute LVF.
C - Lymphatic obstruction is not a direct consequence of LVF; edema is primarily
hydrostatic.
D - Increased permeability occurs in ARDS, not typically in acute cardiogenic
pulmonary edema.
Reference: Huether & McCance (2026). Understanding Pathophysiology, 8th Ed., Ch. 32
Q4. A patient in hypovolemic shock initially shows tachycardia, cool extremities, and
a urine output of 20 mL/hour. Which compensatory mechanism is primarily
responsible for the oliguria?
A. Increased atrial natriuretic peptide (ANP) release causing renal vasodilation
B. Activation of the renin-angiotensin-aldosterone system (RAAS) leading to renal
vasoconstriction and sodium/water retention
C. Direct ischemic injury to the renal tubules due to low perfusion pressure
D. Sympathetically mediated afferent arteriolar vasodilation to preserve glomerular
filtration
