1. Which cellular adaptation occurs when a tissue is exposed to
increased workload but the individual cells cannot divide?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Metaplasia
• Answer: B. Hypertrophy
• Rationale: Hypertrophy is an increase in individual cell size
that commonly occurs when tissues such as skeletal or cardiac
muscle experience increased workload.
2. Which cellular process involves programmed, energy-
dependent cell death?
A. Necrosis
B. Autolysis
C. Apoptosis
D. Ischemia
• Answer: C. Apoptosis
• Rationale: Apoptosis is regulated cell death that removes
damaged or unnecessary cells while generally producing
minimal surrounding inflammation.
3. Which finding is most characteristic of cellular hypoxic injury?
,A. Increased ATP production
B. Failure of the sodium-potassium pump
C. Increased oxidative phosphorylation
D. Increased intracellular pH
• Answer: B. Failure of the sodium-potassium pump
• Rationale: Reduced oxygen decreases ATP production. ATP-
dependent membrane pumps become impaired, allowing sodium
and water to accumulate intracellularly and causing cellular
swelling.
4. What is the primary consequence of mitochondrial dysfunction
during severe cellular injury?
A. Increased ATP production
B. Decreased ATP production
C. Increased protein synthesis
D. Increased cellular oxygenation
• Answer: B. Decreased ATP production
• Rationale: Mitochondria generate most cellular ATP through
oxidative phosphorylation. Mitochondrial damage therefore
compromises energy production.
5. Which substance is an example of a reactive oxygen species?
A. Sodium chloride
B. Hydroxyl radical
C. Albumin
D. Hemoglobin
• Answer: B. Hydroxyl radical
• Rationale: Reactive oxygen species include highly reactive
molecules such as hydroxyl radicals that can damage lipids,
proteins, and DNA.
6. A patient develops tissue injury after restoration of blood flow
to previously ischemic tissue. What process is occurring?
,A. Metaplasia
B. Reperfusion injury
C. Hyperplasia
D. Coagulation
• Answer: B. Reperfusion injury
• Rationale: Reintroduction of oxygen can generate reactive
oxygen species and inflammatory responses that cause
additional cellular injury.
7. Which type of necrosis is most commonly associated with
myocardial infarction?
A. Liquefactive
B. Caseous
C. Coagulative
D. Fat
• Answer: C. Coagulative
• Rationale: Ischemic injury in most solid organs, including the
heart, typically produces coagulative necrosis.
8. Which type of necrosis is classically associated with central
nervous system infarction?
A. Coagulative
B. Liquefactive
C. Fat
D. Fibrinoid
• Answer: B. Liquefactive
• Rationale: Brain tissue undergoes liquefactive necrosis after
ischemic injury because enzymatic digestion rapidly breaks
down the damaged tissue.
9. What is the primary purpose of cellular adaptation?
A. To permanently destroy damaged cells
B. To allow cells to survive altered environmental conditions
, C. To prevent all inflammatory responses
D. To increase genetic mutations
• Answer: B. To allow cells to survive altered environmental
conditions
• Rationale: Cellular adaptations such as hypertrophy,
hyperplasia, atrophy, and metaplasia allow cells to adjust to
stress and maintain viability.
10. Which adaptation involves replacement of one mature
differentiated cell type by another mature cell type?
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
• Answer: C. Metaplasia
• Rationale: Metaplasia is a potentially reversible adaptive
change in which one differentiated cell type is replaced by
another better suited to the stressful environment.
11. Which mechanism is primarily responsible for edema caused
by severe hypoalbuminemia?
A. Increased plasma oncotic pressure
B. Decreased plasma oncotic pressure
C. Increased lymphatic drainage
D. Decreased capillary permeability
• Answer: B. Decreased plasma oncotic pressure
• Rationale: Albumin contributes substantially to plasma colloid
osmotic pressure. Low albumin reduces the force retaining fluid
within the vascular space, promoting movement of fluid into
tissues.
12. Which Starling force normally promotes movement of fluid
out of capillaries?
