1. Pathophysiology is the study of:
A. Normal anatomy only
B. Disease processes and their effects on body function
C. Surgical interventions
D. Medication administration exclusively
Correct Answer: B
Rationale: Pathophysiology focuses on the mechanisms of disease and how alterations in
normal physiology produce clinical manifestations.
2. Homeostasis refers to the body's ability to:
A. Maintain a stable internal environment
B. Eliminate all disease processes
C. Increase metabolic activity continuously
D. Prevent aging
Correct Answer: A
Rationale: Homeostasis involves maintaining physiological balance despite internal and
external changes.
3. The basic structural and functional unit of the body is the:
A. Organ
B. Tissue
C. Cell
D. Organ system
,Correct Answer: C
Rationale: Cells are the fundamental units responsible for carrying out life processes.
4. Cellular hypertrophy is characterized by:
A. Increased cell number
B. Increased cell size
C. Cell death
D. Cellular mutation
Correct Answer: B
Rationale: Hypertrophy occurs when cells enlarge in response to increased workload or
stimulation.
5. Hyperplasia refers to:
A. Increased cell size
B. Increased cell number
C. Cell destruction
D. Cellular degeneration
Correct Answer: B
Rationale: Hyperplasia involves an increase in the number of cells within a tissue or
organ.
6. Atrophy results in:
A. Increased organ size
B. Reduced cell size and function
C. Increased cell proliferation
D. Malignant transformation
Correct Answer: B
Rationale: Atrophy occurs when cells decrease in size because of reduced workload, aging,
or inadequate nutrition.
7. Which cellular adaptation involves replacement of one mature cell type with another?
, A. Dysplasia
B. Necrosis
C. Metaplasia
D. Apoptosis
Correct Answer: C
Rationale: Metaplasia is a reversible adaptation often resulting from chronic irritation.
8. Dysplasia is characterized by:
A. Normal cell growth
B. Abnormal cellular development and organization
C. Programmed cell death
D. Tissue regeneration only
Correct Answer: B
Rationale: Dysplasia involves abnormal growth patterns that may precede malignant
transformation.
9. Apoptosis is best described as:
A. Accidental cell death
B. Programmed cell death
C. Inflammatory cell injury
D. Ischemic necrosis
Correct Answer: B
Rationale: Apoptosis is a controlled process that removes damaged or unnecessary cells.
10. Necrosis differs from apoptosis because it:
A. Is programmed
B. Causes inflammation and tissue injury
C. Occurs normally during development
D. Does not affect surrounding tissue
Correct Answer: B
Rationale: Necrosis results from injury and typically triggers inflammation.
