SECTION I: CELLULAR BIOLOGY, ADAPTATION, AND INJURY
🟢 1. A 58-year-old male with long-standing hypertension develops thickening of the left ventricular
wall. Which cellular adaptation best explains this finding?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
🔴 Correct Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in cell size, leading to organ enlargement, commonly seen in
cardiac muscle subjected to increased workload (e.g., hypertension). Hyperplasia (A) involves increased
cell number, metaplasia (C) is a reversible change of one cell type to another, and dysplasia (D) is
disordered growth.
🟢 2. A patient with chronic anemia develops fatigue and pallor. Which cellular adaptation is most
likely occurring in response to decreased oxygen-carrying capacity?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
🔴 Correct Answer: B. Atrophy
Rationale: Atrophy is a decrease in cell size due to reduced workload or decreased blood supply
(hypoxia). In chronic anemia, reduced oxygen delivery leads to cellular shrinkage.
🟢 3. A smoker develops squamous metaplasia in the bronchial epithelium. What is the primary
stimulus for this change?
,A. Hormonal stimulation
B. Chronic irritation
C. Increased workload
D. Nutritional deficiency
🔴 Correct Answer: B. Chronic irritation
Rationale: Metaplasia is a reversible change where one differentiated cell type replaces another in
response to chronic irritation, such as cigarette smoke.
🟢 4. Which cellular change is considered premalignant and involves abnormal cell size, shape, and
organization?
A. Atrophy
B. Hypertrophy
C. Dysplasia
D. Metaplasia
🔴 Correct Answer: C. Dysplasia
Rationale: Dysplasia is disordered cell growth; it is often reversible but can progress to carcinoma in
situ.
🟢 5. A 62-year-old male experiences a myocardial infarction. Which type of necrosis is most commonly
seen in the heart after ischemic injury?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
🔴 Correct Answer: C. Coagulative necrosis
Rationale: Coagulative necrosis preserves tissue architecture for days and is typical in ischemic solid
organs such as the heart and kidney.
🟢 6. Caseous necrosis is characteristic of which disease?
A. Myocardial infarction
B. Tuberculosis
C. Pancreatitis
D. Cerebral infarction
🔴 Correct Answer: B. Tuberculosis
Rationale: Caseous necrosis appears cheese-like, with granulomatous inflammation, and is typical in
tuberculosis.
🟢 7. Which form of cell death is genetically programmed and does not trigger inflammation?
A. Necrosis
B. Apoptosis
, C. Oncosis
D. Coagulative necrosis
🔴 Correct Answer: B. Apoptosis
Rationale: Apoptosis is genetically controlled cell death that eliminates damaged cells without triggering
an inflammatory response.
🟢 8. Free radical injury primarily causes cellular damage through which mechanism?
A. DNA alkylation
B. Lipid peroxidation of cell membranes
C. Protein denaturation
D. Mitochondrial fission
🔴 Correct Answer: B. Lipid peroxidation of cell membranes
Rationale: Free radicals attack polyunsaturated fatty acids, leading to membrane damage and cell lysis.
🟢 9. Carbon monoxide causes tissue damage primarily by which mechanism?
A. Competing with carbon dioxide for excretion
B. Binding to hemoglobin and preventing oxygen transport
C. Destroying chemical bonds of hemoglobin
D. Removing iron from hemoglobin
🔴 Correct Answer: B. Binding to hemoglobin and preventing oxygen transport
Rationale: Carbon monoxide binds to hemoglobin with high affinity, forming carboxyhemoglobin and
preventing oxygen carriage.
🟢 10. Which cellular organelle is the primary site of ATP production and is most vulnerable to hypoxic
injury?
A. Lysosome
B. Ribosome
C. Mitochondria
D. Golgi apparatus
🔴 Correct Answer: C. Mitochondria
Rationale: Mitochondria produce ATP via oxidative phosphorylation; hypoxia halts this process, leading
to energy failure.
🟢 11. Low plasma albumin causes edema primarily due to a reduction in which pressure?
A. Hydrostatic pressure
B. Oncotic pressure
C. Osmotic pressure
D. Capillary permeability
🔴 Correct Answer: B. Oncotic pressure
Rationale: Low plasma albumin reduces oncotic pressure, decreasing water reabsorption into capillaries,
leading to edema.
