Instructions: Select the single best answer for each question. Correct answers
are highlighted in bold. A rationale is provided for each answer.
Section A: Cellular Adaptation & Injury (Qs 1-10)
1. A patient with chronic hepatitis C develops liver scarring and nodules. This
represents which cellular adaptation?
• A. Hyperplasia
• B. Metaplasia
• C. Dysplasia
• D. Anaplasia
Rationale: Dysplasia refers to disorganized growth and loss of cellular uniformity,
often a precursor to neoplasia in chronic liver disease.
2. Which of the following is the earliest reversible change in ischemia?
• A. Cellular swelling
• B. Nuclear pyknosis
, • C. Karyorrhexis
• D. Fatty change
Rationale: Cellular swelling due to Na+/K+ pump failure is the first reversible
hypoxic change.
3. Liquefactive necrosis is characteristically seen in:
• A. Myocardial infarction
• B. Brain infarction
• C. Tuberculous lung lesion
• D. Ischemic limb
Rationale: Brain lacks significant connective tissue, leading to enzymatic
liquefaction.
4. A hallmark of irreversible cell injury is:
• A. ATP depletion
• B. Anaerobic glycolysis
• C. Severe mitochondrial vacuolization
• D. Reduced protein synthesis
Rationale: Irreversible injury features severe mitochondrial damage and
membrane rupture.
5. Which of the following is an example of pathologic hyperplasia?
• A. Breast enlargement during pregnancy
• B. Uterine enlargement in pregnancy
• C. Benign prostatic hyperplasia
• D. Liver regeneration after partial hepatectomy
Rationale: BPH is abnormal proliferation not driven by physiological need.
6. The most common cause of fatty liver (steatosis) in Western countries is:
• A. Protein malnutrition
, • B. Hepatitis C
• C. Alcohol use disorder
• D. Reye syndrome
Rationale: Alcohol alters fatty acid oxidation and triglyceride export.
7. Dystrophic calcification is best described as:
• A. Calcium deposition with normal serum calcium
• B. Calcium deposition in dead/dying tissue
• C. Calcium deposition in kidneys due to hypercalcemia
• D. Metastatic calcification in lungs
Rationale: Dystrophic calcification occurs in necrotic tissue despite normal
calcium levels.
8. Which oxidative stress marker is currently used in 2026 clinical practice to
predict organ failure?
• A. Malondialdehyde
• B. F2-isoprostanes
• C. Superoxide dismutase
• D. Catalase
Rationale: F2-isoprostanes are stable, specific markers of lipid peroxidation now
integrated into ICU scoring systems.
9. Apoptosis is characterized by:
• A. Cell shrinkage and caspase activation
• B. Cell swelling and inflammation
• C. Random DNA fragmentation
• D. Loss of membrane integrity early
Rationale: Apoptosis is programmed, non-inflammatory, caspase-mediated cell
death.
