Instructions: Choose the single best answer for each question. Correct answers
are highlighted in bold. A rationale follows each answer.
Section 1: Cellular & General Pathophysiology (Questions 1–10)
1. A patient with chronic ischemia develops cell death due to lack of ATP. This
type of necrosis is most likely:
• A) Caseous necrosis
• B) Coagulative necrosis
• C) Liquefactive necrosis
• D) Fat necrosis
Rationale: Coagulative necrosis is typical in hypoxic (ischemic) injury of all solid
organs except the brain. ATP depletion causes protein denaturation.
2. Which cellular adaptation is characterized by an increase in cell size
without cell division?
• A) Hyperplasia
• B) Hypertrophy
• C) Atrophy
• D) Metaplasia
Rationale: Hypertrophy refers to increased cell size (e.g., cardiac myocytes in
hypertension). Hyperplasia is increased cell number.
,3. The hallmark of apoptosis includes:
• A) Inflammation and swelling
• B) Cell shrinkage and caspase activation
• C) Rupture of lysosomes
• D) Random DNA degradation
Rationale: Apoptosis is programmed cell death with caspase activation, cell
shrinkage, and no inflammation.
4. Free radical injury leads to (choose the best option):
• A) Increased superoxide dismutase
• B) Lipid peroxidation of cell membranes
• C) Decreased intracellular calcium
• D) Increased ATP synthesis
Rationale: Reactive oxygen species attack polyunsaturated fatty acids in
membranes → lipid peroxidation → loss of membrane integrity.
5. A change from normal columnar epithelium to stratified squamous
epithelium in the bronchus is an example of:
• A) Dysplasia
• B) Metaplasia
• C) Anaplasia
• D) Neoplasia
Rationale: Metaplasia is a reversible change from one differentiated cell type to
another, often due to chronic irritation (e.g., smoking).
6. Which laboratory finding indicates liquefactive necrosis?
• A) PUS formation and enzymatic breakdown
• B) Dry, cheesy material
• C) White, chalky deposits
• D) Preserved tissue architecture
, Rationale: Liquefactive necrosis occurs in the brain and bacterial infections,
characterized by pus and enzymatic dissolution.
7. The most common intracellular accumulation in alcoholic liver disease is:
• A) Glycogen
• B) Triglycerides (fatty change)
• C) Proteins (hyaline)
• D) Urate crystals
Rationale: Alcohol metabolism increases NADH, promoting fatty acid synthesis
→ steatosis (triglyceride accumulation in hepatocytes).
8. Dystrophic calcification differs from metastatic calcification in that
dystrophic calcification:
• A) Occurs in dead or damaged tissue with normal serum calcium
• B) Occurs in normal tissues with hypercalcemia
• C) Is reversible
• D) Only affects blood vessels
Rationale: Dystrophic calcification occurs in necrotic tissue despite normal
calcium levels; metastatic calcification requires hypercalcemia.
9. Which injury pattern is associated with reperfusion after ischemia?
• A) Reduced free radical production
• B) Increased mitochondrial calcium and ROS
• C) Decreased inflammation
• D) Enhanced ATP synthesis
Rationale: Reperfusion reintroduces oxygen, leading to a burst of reactive oxygen
species (ROS) and calcium overload, worsening injury.
10. A biopsy shows “watery” swelling of hepatocytes with dilated ER. This is
most likely:
• A) Hydropic change (reversible injury)
