Section 1: Cellular Adaptation, Injury, and Death (25 Questions)
1. A patient with chronic anemia develops increased cardiac output and
hyperpigmentation of skin. Which cellular adaptation is most likely occurring
in the myocardium?
• A) Atrophy
• B) Metaplasia
• C) Hypertrophy
• D) Dysplasia
Rationale: Hypertrophy is an increase in cell size due to increased workload (e.g.,
chronic anemia causes increased cardiac work). Atrophy is shrinkage; metaplasia is
reversible change of cell type; dysplasia is disordered growth.
2. A smoker’s bronchial epithelium changes from ciliated pseudostratified to
stratified squamous. This is an example of:
• A) Hyperplasia
• B) Metaplasia
, • C) Anaplasia
• D) Necrosis
Rationale: Metaplasia is the reversible replacement of one differentiated cell type
by another, often due to chronic irritation (smoking).
3. Which type of necrosis is most characteristic of tuberculosis?
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Caseous necrosis
• D) Fat necrosis
Rationale: Caseous necrosis (cheese-like appearance) is hallmark of TB.
Coagulative = ischemic kidney/heart; liquefactive = brain; fat = pancreatitis.
4. A patient with myocardial infarction shows tissue with preserved
architecture but no nuclei. This is:
• A) Coagulative necrosis
• B) Liquefactive necrosis
• C) Gangrenous necrosis
• D) Fibrinoid necrosis
Rationale: Coagulative necrosis preserves tissue outlines but cells are dead;
typical in solid organs (heart, kidney) following ischemia.
5. Which cellular change is reversible?
• A) Karyolysis
• B) Karyorrhexis
• C) Cellular swelling
• D) Pyknosis
Rationale: Cellular swelling (hydropic change) is an early reversible injury.
Karyolysis, karyorrhexis, and pyknosis indicate irreversible cell death.
6. Apoptosis is characterized by:
, • A) Inflammation
• B) Cell swelling
• C) Cell shrinkage and DNA fragmentation
• D) Enzyme leakage
Rationale: Apoptosis is programmed cell death with cell shrinkage, nuclear
fragmentation, no inflammation. Necrosis causes swelling and inflammation.
7. Dystrophic calcification is most likely to develop in:
• A) Damaged heart valve
• B) Hyperparathyroidism
• C) Vitamin D toxicity
• D) Chronic kidney disease
Rationale: Dystrophic calcification occurs in dead or damaged tissue with normal
calcium levels (e.g., atherosclerotic plaques, damaged valves). Metastatic
calcification involves hypercalcemia.
8. A patient with chronic alcohol use develops liver atrophy. The mechanism
most likely involves:
• A) Increased workload
• B) Decreased blood supply
• C) Decreased protein synthesis and increased autophagy
• D) Hormonal stimulation
Rationale: Atrophy results from decreased nutrient supply, disuse, or reduced
hormonal signaling (autophagy increases).
9. Which of the following is a feature of irreversible cell injury?
• A) Blebbing of cell membrane
• B) Rupture of lysosomal membranes
• C) Loss of microvilli
• D) Ribosomal detachment
