ANSWERS & DETAILED RATIONALES 2026/2027
UPDATED
1. Which statement best describes pathophysiology?
A. The study of normal human anatomy only
B. The study of altered physiological processes associated with disease
C. The study of medications exclusively
D. The study of surgical procedures
Correct Answer: B. The study of altered physiological processes associated with disease
Rationale: Pathophysiology examines how disease or injury alters normal cellular, tissue, organ,
and systemic function.
2. Which concept refers to maintenance of a relatively stable internal environment?
A. Metaplasia
B. Homeostasis
C. Necrosis
D. Hypertrophy
Correct Answer: B. Homeostasis
Rationale: Homeostasis is the body's ability to maintain internal conditions within appropriate
physiological ranges despite internal and external changes.
3. A patient develops cellular enlargement in response to increased workload. Which
adaptation is occurring?
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: B. Hypertrophy
Rationale: Hypertrophy involves an increase in individual cell size, commonly occurring when
tissues experience increased workload.
,4. Which cellular adaptation involves an increase in cell number?
A. Hyperplasia
B. Hypertrophy
C. Atrophy
D. Necrosis
Correct Answer: A. Hyperplasia
Rationale: Hyperplasia occurs when cells proliferate, increasing the number of cells within a
tissue or organ.
5. Which condition is most likely to cause cellular atrophy?
A. Increased workload
B. Prolonged immobilization
C. Increased hormonal stimulation
D. Increased nutritional intake
Correct Answer: B. Prolonged immobilization
Rationale: Lack of use reduces cellular workload and can cause muscle fibers and other tissues
to decrease in size.
6. Which process is characterized by replacement of one mature cell type by another?
A. Metaplasia
B. Hypertrophy
C. Apoptosis
D. Necrosis
Correct Answer: A. Metaplasia
Rationale: Metaplasia is an adaptive and potentially reversible substitution of one differentiated
cell type for another better suited to a chronic stress.
7. Which cellular process is programmed and generally does not produce extensive
inflammation?
,A. Necrosis
B. Apoptosis
C. Gangrene
D. Ischemia
Correct Answer: B. Apoptosis
Rationale: Apoptosis is regulated cell death in which cellular components are removed in an
organized manner.
8. Which feature is most characteristic of necrosis?
A. Controlled cell removal
B. Cellular swelling and membrane disruption
C. Normal cell turnover
D. Increased cellular differentiation
Correct Answer: B. Cellular swelling and membrane disruption
Rationale: Necrosis involves irreversible cell injury, membrane disruption, leakage of cellular
contents, and often inflammation.
9. What is a major consequence of severe ATP depletion?
A. Increased sodium-potassium pump activity
B. Failure of energy-dependent membrane pumps
C. Increased protein synthesis
D. Increased oxygen delivery
Correct Answer: B. Failure of energy-dependent membrane pumps
Rationale: ATP is required for active transport. ATP depletion impairs the sodium-potassium
pump, resulting in intracellular sodium and water accumulation.
10. Which organelle is most directly responsible for aerobic ATP production?
A. Lysosome
B. Mitochondrion
C. Ribosome
D. Golgi apparatus
, Correct Answer: B. Mitochondrion
Rationale: Mitochondria generate most cellular ATP through oxidative phosphorylation.
11. Ischemia is best defined as:
A. Reduced blood flow to tissue
B. Increased oxygen delivery
C. Increased blood glucose
D. Increased cellular metabolism
Correct Answer: A. Reduced blood flow to tissue
Rationale: Ischemia reduces delivery of oxygen and nutrients while impairing removal of
metabolic waste.
12. Why is ischemia often more damaging than hypoxia alone?
A. It reduces oxygen but increases nutrient delivery
B. It reduces blood flow, limiting oxygen and nutrient delivery and waste removal
C. It increases ATP production
D. It prevents cellular injury
Correct Answer: B. It reduces blood flow, limiting oxygen and nutrient delivery and waste
removal
Rationale: Ischemia affects multiple components of tissue perfusion, not simply oxygen
availability.
13. Which substance contributes to cellular damage through oxidative stress?
A. Reactive oxygen species
B. Albumin
C. Insulin
D. Sodium bicarbonate
Correct Answer: A. Reactive oxygen species
Rationale: Reactive oxygen species can damage membrane lipids, proteins, and DNA when
antioxidant defenses are overwhelmed.
