are highlighted in bold.
Section 1: Cellular Adaptation & Injury (Questions 1–10)
1. A patient with chronic anemia develops an enlarged spleen due to increased
workload. This enlargement is best described as:
• A) Hyperplasia
• B) Hypertrophy
• C) Atrophy
• D) Metaplasia
Rationale: Hypertrophy is an increase in cell size due to increased workload
(e.g., anemia causing cardiac/splenic enlargement). Hyperplasia is
increased cell number.
2. A smoker’s bronchial epithelium changes from pseudostratified ciliated
columnar to stratified squamous. This is an example of:
• A) Dysplasia
• B) Hyperplasia
, • C) Anaplasia
• D) Metaplasia
Rationale: Metaplasia is a reversible change of one differentiated cell type
to another (e.g., squamous metaplasia in airways due to chronic irritation).
3. Ischemic injury to a kidney tubular cell leads to ATP depletion. Which of
the following cellular events occurs FIRST?
• A) Loss of Na+/K+ pump function
• B) Calcium influx into mitochondria
• C) DNA fragmentation
• D) Activation of caspases
Rationale: ATP depletion first impairs Na+/K+ ATPase, causing cellular
swelling. Calcium influx and apoptosis occur later.
4. Reversible cell injury is characterized by:
• A) Nuclear pyknosis
• B) Karyorrhexis
• C) Cellular swelling and fatty change
• D) Myelin figures
Rationale: Cellular swelling and fatty change are reversible; nuclear
changes (pyknosis, karyorrhexis) indicate irreversible injury/necrosis.
5. Liquefactive necrosis is classically seen in:
• A) Brain infarction
• B) Myocardial infarction
• C) TB granuloma
• D) Ischemic limb
Rationale: Brain has abundant lipids/enzymes → liquefaction. MI is
coagulative; TB is caseous.
6. Caseous necrosis is most characteristic of:
• A) Ischemic heart disease
, • B) Acute pancreatitis
• C) Tuberculosis
• D) Venous infarction
Rationale: Caseous necrosis (cheese-like) is pathognomonic for TB; caused
by Mycobacterium tuberculosis.
7. Which type of necrosis is associated with enzymatic digestion of fat?
• A) Coagulative
• B) Fat necrosis
• C) Fibrinoid
• D) Gangrenous
Rationale: Fat necrosis occurs in pancreatitis or breast trauma; lipases
break triglycerides → fatty acids + calcium (saponification).
8. A patient with a chronic leg ulcer develops black, dry, shriveled tissue. This
is:
• A) Wet gangrene
• B) Dry gangrene
• C) Gas gangrene
• D) Fournier’s gangrene
Rationale: Dry gangrene = coagulative necrosis + mummification (no
infection). Wet gangrene has bacterial superinfection.
9. Which cellular change is an adaptive response to decreased workload (e.g.,
cast immobilization)?
• A) Hyperplasia
• B) Hypertrophy
• C) Atrophy
• D) Metaplasia
Rationale: Atrophy = decreased cell size/function due to disuse, denervation,
or ischemia.
