MODULE 1: Cellular Adaptation, Injury, Inflammation & Immunity (20 Questions)
Q1: A woman's breast tissue enlarges during pregnancy due to increased estrogen stimulation.
This is an example of:
A. Hypertrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia
Answer: B
Rationale: Hyperplasia involves an increase in the number of cells. Breast tissue enlargement
during pregnancy results from estrogen-stimulated proliferation of glandular epithelial cells,
which is a physiologic hyperplasia.
Q2: A smoker develops changes in the bronchial epithelium where ciliated columnar cells are
replaced by stratified squamous cells. This is:
A. Dysplasia
B. Metaplasia
C. Anaplasia
D. Hyperplasia
Answer: B
Rationale: Metaplasia is the reversible replacement of one mature cell type with another. In
,smokers, chronic irritation causes ciliated columnar epithelium to be replaced by stratified
squamous epithelium.
Q3: Which cellular adaptation is considered a premalignant change?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Answer: D
Rationale: Dysplasia involves disorganized cellular growth with abnormal cell size, shape, and
organization. It is considered a premalignant change because it may progress to carcinoma in situ
and invasive cancer.
Q4: A patient's muscle mass decreases after prolonged bed rest. This is an example of:
A. Atrophy
B. Hypertrophy
C. Hyperplasia
D. Metaplasia
Answer: A
Rationale: Atrophy is a decrease in cell size. Disuse atrophy occurs when muscles are not used,
leading to decreased protein synthesis and increased protein degradation.
Q5: Which type of cell death is energy-dependent and requires ATP?
A. Necrosis
B. Apoptosis
C. Coagulative necrosis
D. Liquefactive necrosis
Answer: B
Rationale: Apoptosis is an active, energy-dependent process requiring ATP. It involves activation
of caspases and controlled cellular self-destruction without inflammation.
,Q6: A patient experiences a myocardial infarction. The area of dead heart muscle would most
likely show which type of necrosis?
A. Liquefactive necrosis
B. Caseous necrosis
C. Coagulative necrosis
D. Fat necrosis
Answer: C
Rationale: Coagulative necrosis occurs in tissues deprived of blood supply (ischemia), such as
the heart, kidney, and spleen. The tissue architecture is preserved initially, with a firm texture.
Q7: Which of the following is the most common cause of cellular injury?
A. Physical agents
B. Chemical agents
C. Hypoxia
D. Infectious agents
Answer: C
Rationale: Hypoxia (oxygen deprivation) is the most common and important cause of cellular
injury. It leads to ATP depletion and failure of the sodium-potassium pump.
Q8: A patient with a crush injury develops acute kidney injury due to myoglobin release. This is
an example of:
A. Hypoxic injury
B. Direct mechanical injury
C. Chemical injury
D. Ischemic-reperfusion injury
Answer: C
Rationale: Myoglobin released from crushed muscle is toxic to the kidneys and causes direct
chemical injury to renal tubular cells, leading to acute kidney injury.
Q9: Which of the following is a characteristic of irreversible cellular injury?
A. Cellular swelling
B. Reversible membrane blebbing
C. Severe mitochondrial dysfunction and loss of membrane integrity
D. Increased ATP production
, Answer: C
Rationale: Irreversible injury is associated with severe mitochondrial dysfunction, loss of
membrane integrity, and inability to restore cellular function even if the injurious stimulus is
removed.
Q10: Which mediator is responsible for the classic signs of inflammation including redness,
heat, swelling, and pain?
A. Cortisol
B. Histamine
C. Insulin
D. Thyroxine
Answer: B
Rationale: Histamine released from mast cells causes vasodilation (redness, heat) and increased
vascular permeability (swelling), and stimulates pain receptors.
Q11: Which of the following is a systemic manifestation of acute inflammation?
A. Fever
B. Leukocytosis
C. Increased erythrocyte sedimentation rate
D. All of the above
Answer: D
Rationale: Systemic manifestations of acute inflammation include fever, leukocytosis, increased
ESR, and increased acute-phase reactants such as C-reactive protein.
Q12: Which immunoglobulin is the first to be produced in a primary immune response?
A. IgG
B. IgM
C. IgA
D. IgE
Answer: B
Rationale: IgM is the first immunoglobulin produced in a primary immune response. It is a
pentamer with high avidity for antigens and is an efficient activator of the complement system.
