rationale follows each question.
Section 1: Cellular Adaptation & Injury (Questions 1–10)
1. A patient with chronic liver disease develops enlarged, fatty liver cells. This
is an example of:
• A. Hyperplasia
• B. Metaplasia
• C. Fatty change (steatosis)
• D. Dystrophic calcification
Rationale: Steatosis is abnormal accumulation of lipids in parenchymal
cells due to toxic or metabolic injury (e.g., alcohol, diabetes).
2. Which cellular adaptation is irreversible and leads to cell death?
• A. Atrophy
• B. Hypertrophy
• C. Necrosis
, • D. Hyperplasia
Rationale: Necrosis is pathologic cell death; atrophy, hypertrophy, and
hyperplasia are reversible adaptations.
3. Liquefactive necrosis is most commonly seen in:
• A. Heart after MI
• B. Brain after stroke
• C. Kidney infarction
• D. Tuberculosis lung
Rationale: Brain tissue undergoes liquefactive necrosis due to high lipid
content and enzymatic digestion.
4. Apoptosis is characterized by:
• A. Inflammation
• B. Swelling of organelles
• C. Fragmentation into apoptotic bodies
• D. Random DNA degradation
Rationale: Apoptosis is programmed, non-inflammatory cell death with
membrane-bound apoptotic bodies.
5. Metaplasia increases cancer risk because:
• A. It causes immediate malignancy
• B. Chronic irritation leads to genetic mutations
• C. Cells become smaller
• D. Apoptosis is blocked
Rationale: Persistent metaplasia creates a microenvironment prone to
dysplastic changes and carcinoma.
6. Dystrophic calcification occurs in:
• A. Necrotic tissue with normal calcium levels
• B. Hypercalcemia from hyperparathyroidism
• C. Normal healthy tissue
, • D. Only bone tissue
Rationale: Dystrophic calcification deposits calcium in dead/dying tissue
despite normal serum calcium.
7. A patient with chronic GERD develops Barrett esophagus. This is:
• A. Hyperplasia
• B. Metaplasia
• C. Dysplasia
• D. Anaplasia
Rationale: Barrett esophagus is replacement of stratified squamous by
columnar epithelium (metaplasia).
8. Hypoxic cell injury initially impairs:
• A. DNA synthesis
• B. Protein synthesis
• C. Aerobic respiration (ATP production)
• D. Cell membrane integrity
Rationale: Lack of oxygen halts oxidative phosphorylation → ATP
depletion → all other failures.
9. Reperfusion injury is mainly due to:
• A. Return of oxygen → oxidative stress
• B. Persistent hypoxia
• C. Electrolyte imbalance only
• D. Hypothermia
Rationale: Sudden reoxygenation generates reactive oxygen species,
causing further damage.
10. Caseous necrosis is hallmark of:
• A. Myocardial infarction
• B. Tuberculosis
• C. Acute pancreatitis
