SECTION 1: CELLULAR FUNCTION & GENETICS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 62-year-old man with a 40-pack-year smoking history presents to the clinic
with a chronic cough. Bronchoscopy reveals that areas of his airway epithelium
have transformed from normal pseudostratified ciliated columnar epithelium
to stratified squamous epithelium. The pathologist describes this change as an
adaptive response to chronic irritation.
A. Atrophy of the airway epithelium
,2
B. Hypertrophy of the goblet cells
C. Metaplasia of the respiratory epithelium ✓ CORRECT
D. Dysplasia with carcinoma in situ
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one differentiated cell
type with another, and in this case, chronic smoking irritation has caused the
airway to switch from columnar to squamous epithelium. Atrophy would
involve shrinkage, not a change in cell type, and dysplasia implies disordered,
pre-malignant growth rather than a simple adaptive substitution. This type of
metaplasia is a known precursor to dysplasia if the irritant persists.
Question 2 of 50
A 45-year-old marathon runner notices that her left ventricle wall appears
thickened on a routine echocardiogram. Her cardiologist explains that this is a
normal physiological adaptation to sustained aerobic training.
A. Pathological hypertrophy from aortic stenosis
B. Physiological hypertrophy from chronic volume overload ✓ CORRECT
C. Hyperplasia of cardiac myocytes
D. Atrophy of the ventricular wall
Correct Answer: B
Rationale: Athlete's heart demonstrates physiological hypertrophy, where
chronic volume overload from endurance training increases chamber size and
wall thickness without pathological signaling. Pathological hypertrophy arises
from pressure overload or disease, and cardiac myocytes are terminally
differentiated cells that do not undergo hyperplasia. This adaptive change is
reversible with deconditioning.

Question 3 of 50
A 58-year-old woman with poorly controlled hypertension is found to have left
ventricular wall thickening on echocardiography. Her cardiologist notes that
this represents a maladaptive response to chronic pressure overload.
A. Physiological hypertrophy from exercise
B. Pathological hypertrophy from increased afterload ✓ CORRECT
C. Metaplasia of the myocardial tissue
D. Apoptosis of cardiac myocytes
Correct Answer: B
Rationale: Chronic pressure overload from hypertension forces the left
ventricle to generate higher systolic pressures, triggering pathological
hypertrophy characterized by fibrosis and eventual diastolic dysfunction.
Physiological hypertrophy is seen in trained athletes, not hypertensive
patients, and metaplasia does not occur in cardiac muscle. Over time, this
pathological remodeling can progress to heart failure.
Question 4 of 50
A 70-year-old man with peripheral artery disease develops dry gangrene of his
left great toe. The tissue appears black, shriveled, and mummified, with a clear
line of demarcation from viable tissue.
A. Liquefactive necrosis with bacterial superinfection
B. Coagulative necrosis without significant bacterial infection ✓ CORRECT
C. Caseous necrosis from tuberculosis
, 4
D. Fat necrosis from pancreatic enzymes
Correct Answer: B
Rationale: Dry gangrene results from chronic ischemia producing coagulative
necrosis, where tissue architecture is preserved but cells are dead, and the lack
of bacterial infection allows the tissue to desiccate and mummify. Liquefactive
necrosis occurs in wet gangrene with bacterial infection, and caseous or fat
necrosis have distinct etiologies unrelated to peripheral vascular disease. The
line of demarcation indicates the boundary between viable and ischemic
tissue.
Question 5 of 50
A 35-year-old man presents to the emergency department 24 hours after a
crush injury to his right leg. He is found to have dark, tea-colored urine and a
serum potassium of 6.8 mEq/L. The pathophysiology involves myocyte
breakdown and release of intracellular contents.
A. Rhabdomyolysis with myoglobin-induced tubular injury ✓ CORRECT
B. Acute glomerulonephritis from immune complex deposition
C. Hepatic failure causing bilirubinuria
D. Disseminated intravascular coagulation
Correct Answer: A
Rationale: Crush injury causes skeletal muscle necrosis, releasing myoglobin
that precipitates in renal tubules and causes acute kidney injury, while
intracellular potassium release produces hyperkalemia. Glomerulonephritis
would present with hematuria and proteinuria, not tea-colored urine from
myoglobin, and hepatic failure causes jaundice, not dark urine from muscle
breakdown. Aggressive fluid resuscitation is essential to prevent renal failure.
