Section 1: Cellular Adaptation & Injury (Questions 1–10)
1. A patient with chronic anemia develops an enlarged spleen. This represents
which type of cellular adaptation?
• A) Hyperplasia
• B) Metaplasia
• C) Hypertrophy
• D) Dysplasia
Rationale: Hypertrophy is an increase in cell size due to increased workload or
demand. Chronic anemia causes increased RBC destruction in the spleen, leading
to splenic macrophage hypertrophy.
2. A smoker develops columnar-to-squamous metaplasia in the bronchi. This
change is:
• A) Reversible and protective
• B) Irreversible and premalignant
, • C) Always malignant
• D) Due to apoptosis
Rationale: Metaplasia is reversible replacement of one differentiated cell type with
another better suited to stress. Squamous metaplasia protects against smoke but can
progress to dysplasia.
3. Which finding is most characteristic of reversible cell injury?
• A) Nuclear pyknosis
• B) Cellular swelling
• C) Karyorrhexis
• D) Membrane blebbing with rupture
Rationale: Cellular swelling (hydropic change) is an early reversible response due
to failure of Na+/K+ ATPase. Pyknosis, karyorrhexis, and membrane rupture
indicate irreversible injury.
4. A myocardial infarction causes coagulative necrosis. Which organ typically
exhibits liquefactive necrosis following a stroke?
• A) Heart
• B) Liver
• C) Brain
• D) Kidney
Rationale: Brain infarction leads to liquefactive necrosis due to abundant
lysosomal enzymes from microglia and neutrophils. Heart, kidney, and liver show
coagulative necrosis.
5. Caseous necrosis is pathognomonic for which condition?
• A) Acute pancreatitis
• B) Tuberculosis
• C) Ischemic bowel
• D) Fat necrosis in breast
, Rationale: Caseous necrosis (soft, cheesy debris) is characteristic of tuberculosis.
Fat necrosis (saponification) occurs in pancreatitis; gangrenous necrosis involves
skin.
6. A hepatocyte undergoing apoptosis would show:
• A) Large inflammatory infiltrate
• B) Cell shrinkage and chromatin condensation
• C) Random DNA fragmentation
• D) Rupture of lysosomes
Rationale: Apoptosis is programmed cell death with cell shrinkage, nuclear
fragmentation, and intact membranes (no inflammation). Necrosis causes swelling,
rupture, and inflammation.
7. Which cellular change is considered an adaptive response in cardiac
myocytes exposed to chronic hypertension?
• A) Hyperplasia
• B) Hypertrophy
• C) Atrophy
• D) Dysplasia
Rationale: Cardiac myocytes terminally differentiated → cannot divide
(hyperplasia). They hypertrophy to increase contractile force against elevated
afterload.
8. Cellular atrophy is often caused by all the following EXCEPT:
• A) Denervation
• B) Reduced blood flow
• C) Increased hormonal stimulation
• D) Malnutrition
Rationale: Atrophy results from decreased workload, denervation, ischemia, or
malnutrition. Increased hormonal stimulation (e.g., TSH in hypothyroidism) causes
hypertrophy/hyperplasia.
