Section A: Cellular Adaptation & Injury (Questions 1–10)
1. A patient with chronic hepatitis B develops liver shrinkage and decreased
function. This cellular change is best described as:
• A. Hypertrophy
• B. Hyperplasia
• C. Metaplasia
• D. Atrophy
Rationale: Atrophy is a decrease in cell size/organ volume after chronic
injury or reduced workload. Hepatitis causes loss of hepatocytes, leading to
shrunken, nonfunctional liver.
2. A chronic smoker develops squamous cell carcinoma after ciliated
pseudostratified columnar cells in bronchi transform into squamous cells.
This process is termed:
• A. Dysplasia
• B. Metaplasia
• C. Anaplasia
, • D. Neoplasia
Rationale: Metaplasia = reversible replacement of one differentiated cell
type with another (smoking → squamous metaplasia). Dysplasia is
disordered growth; anaplasia is loss of differentiation in cancer.
3. Which cellular change is considered a direct precursor to cancer if severe
and persistent?
• A. Physiologic hyperplasia
• B. High-grade dysplasia
• C. Atrophy
• D. Physiologic hypertrophy
Rationale: Dysplasia (abnormal size/shape/organization) is pre-neoplastic.
High-grade dysplasia often progresses to carcinoma in situ.
4. Reversible cell injury is characterized by:
• A. Nuclear pyknosis and karyorrhexis
• B. Cellular swelling and fatty change
• C. Lysosomal rupture and enzyme leakage
• D. Membrane blebbing irreversible stage
Rationale: Cellular swelling (due to Na+/K+ pump failure) and fatty change
(lipid vacuoles) are reversible. Pyknosis, karyorrhexis, and membrane
rupture indicate irreversible injury/necrosis.
5. Myocardial hypertrophy in a patient with long-standing hypertension
represents which type of adaptation?
• A. Pathologic hyperplasia
• B. Pathologic hypertrophy
• C. Physiologic hypertrophy
• D. Metaplasia
Rationale: Increased workload (afterload from HTN) causes myocyte
enlargement – pathologic hypertrophy. Physiologic hypertrophy occurs in
exercise/gravid uterus.
6. Ischemic injury to a neuron becomes irreversible after approximately:
, • A. 1–2 minutes
• B. 4–6 minutes
• C. 20–30 minutes
• D. 1–2 hours
Rationale: Neurons are most sensitive to ischemia; irreversible damage
occurs in 4–6 minutes. Cardiac myocytes tolerate ~20–30 minutes;
fibroblasts hours.
7. The most common cause of cellular injury leading to hypoxia is:
• A. Carbon monoxide poisoning
• B. Severe anemia
• C. Ischemia (reduced blood flow)
• D. High altitude
*Rationale: Ischemia (e.g., atherosclerosis, thrombosis) is the #1 cause of
hypoxia clinically. CO poisoning and anemia cause hypoxemic/anemic
hypoxia but are less common.*
8. Which intracellular event signals irreversible cell injury?
• A. ATP depletion
• B. Loss of microvilli
• C. Massive calcium influx into mitochondria
• D. Ribosomal detachment
*Rationale: Irreversibility occurs when mitochondrial permeability transition
pores open → Ca2+ influx → loss of ATP synthesis → no return. ATP
depletion alone is reversible early.*
9. A liver biopsy shows enlarged hepatocytes with large cytoplasmic lipid
vacuoles pushing nucleus to the edge. This is:
• A. Hydropic swelling
• B. Fatty change (steatosis)
• C. Glycogen accumulation
