ORIGINAL QUESTIONS WITH RATIONALES
MODULE 1: CELLULAR ADAPTATION, INJURY, INFLAMMATION & IMMUNITY
Questions 1–25
Question 1
A patient with longstanding hypertension develops an enlarged left ventricular myocardium.
Which cellular adaptation best explains this finding?
A) Hyperplasia
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Answer: B
Rationale: Hypertrophy involves an increase in the size of individual cells, leading to
,Page 2 of 68
enlargement of the affected organ. In hypertension, the left ventricle works against increased
pressure, causing cardiac myocytes to enlarge as a compensatory mechanism.
Question 2
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.
Question 3
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, which is better suited to tolerate the stress.
Question 4
Which cellular adaptation is considered a premalignant change?
A) Atrophy
B) Hypertrophy
C) Metaplasia
D) Dysplasia
,Page 3 of 68
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.
Question 5
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.
Question 6
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.
Question 7
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
, Page 4 of 68
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.
Question 8
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.
Question 9
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.
Question 10
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
