MODULE 1: Cellular Adaptation, Injury, Inflammation & Immunity (20 Questions)
Q1: A patient's cardiac muscle cells increase in size in response to chronic hypertension. This is
an example of:
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Answer: B
Rationale: Hypertrophy is an increase in individual cell size in response to increased workload.
Cardiac muscle cells are terminally differentiated and cannot divide, so they enlarge instead.
Q2: Which cellular adaptation is characterized by a reversible change from one mature cell type
to another?
A. Atrophy
B. Dysplasia
C. Metaplasia
D. Anaplasia
Answer: C
Rationale: Metaplasia is the reversible replacement of one mature differentiated cell type with
another, often in response to chronic irritation.
,Q3: A cervical biopsy shows disorganized cellular growth with variation in cell size and shape.
This finding is most consistent with:
A. Metaplasia
B. Dysplasia
C. Hypertrophy
D. Atrophy
Answer: B
Rationale: Dysplasia involves abnormal cell size, shape, and organization. It is considered a
premalignant change.
Q4: Which type of cell death is characterized by cell swelling, rupture, and inflammation?
A. Apoptosis
B. Necrosis
C. Autophagy
D. Senescence
Answer: B
Rationale: Necrosis is uncontrolled cell death with loss of membrane integrity, cell swelling,
rupture, and release of intracellular contents that trigger inflammation.
Q5: A patient with a myocardial infarction has coagulative necrosis of the heart muscle. Which
feature is typical of coagulative necrosis?
A. Liquefaction of tissue
B. Preservation of tissue architecture
C. Cheesy white appearance
D. Saponification
Answer: B
Rationale: Coagulative necrosis preserves the basic tissue architecture for a time, with a firm
texture. It is typical of ischemic injury in the heart, kidney, and spleen.
Q6: Which type of necrosis is characteristic of a brain infarct?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fat
,Answer: B
Rationale: Liquefactive necrosis occurs in the brain because of its high lipid content and lack of
structural support, leading to enzymatic digestion and liquefaction.
Q7: A patient with tuberculosis has a lung lesion with a cheesy, white appearance. This is:
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
Answer: C
Rationale: Caseous necrosis is characteristic of tuberculosis. It appears as a cheesy, white
material and represents a combination of coagulative and liquefactive necrosis.
Q8: Which mechanism is primarily responsible for cellular swelling during reversible injury?
A. Increased protein synthesis
B. Failure of the sodium-potassium pump
C. Increased lysosomal activity
D. Increased DNA replication
Answer: B
Rationale: ATP depletion impairs Na⁺/K⁺-ATPase activity, causing sodium and water
accumulation inside the cell, leading to hydropic swelling.
Q9: Reperfusion injury is primarily mediated by:
A. Reduced oxygen availability
B. Reactive oxygen species
C. Decreased calcium entry
D. Reduced inflammatory signaling
Answer: B
Rationale: Reintroduction of oxygen during reperfusion generates reactive oxygen species
(ROS), which damage lipids, proteins, DNA, and cellular membranes.
Q10: Which enzyme converts superoxide into hydrogen peroxide?
A. Catalase
B. Superoxide dismutase
, C. Glutathione peroxidase
D. Myeloperoxidase
Answer: B
Rationale: Superoxide dismutase (SOD) converts superoxide into hydrogen peroxide, which is
then detoxified by catalase or glutathione peroxidase.
Q11: Which complement component is most important for opsonization?
A. C3b
B. C5a
C. C9
D. Factor B
Answer: A
Rationale: C3b binds to microbial surfaces and enhances phagocytosis by facilitating recognition
by phagocytes.
Q12: A patient develops hives and wheezing after eating peanuts. Which type of hypersensitivity
is this?
A. Type I
B. Type II
C. Type III
D. Type IV
Answer: A
Rationale: Type I hypersensitivity is IgE-mediated and involves mast cell degranulation with
release of histamine, causing urticaria and bronchospasm.
Q13: Which antibody is primarily responsible for Type I hypersensitivity?
A. IgG
B. IgM
C. IgE
D. IgA
Answer: C
Rationale: IgE binds to Fc receptors on mast cells and basophils. Cross-linking by allergen
triggers degranulation and release of inflammatory mediators.
