, SECTION 1: Cellular Pathophysiology — Cell Injury, Adaptation, Death, Inflammation,
Immunity (Q1–Q8)
Q1. A patient with ischemic heart disease has myocardial cells that are reversibly injured.
Which cellular adaptation is most likely occurring?
A. Necrosis
B. Cellular hypertrophy
C. Cellular atrophy
D. Reversible cellular swelling
Answer: D
Rationale: Reversible cellular swelling is the most common early response to hypoxia/ischemia, caused
by failure of the sodium-potassium ATPase pump leading to sodium and water accumulation. If oxygen
is restored, cells can return to normal. If ischemia persists, irreversible injury and necrosis occur.
Hypertrophy is an increase in cell size, and atrophy is a decrease in cell size—neither describes this acute
ischemic response.
Q2. Which of the following best describes the difference between apoptosis and necrosis?
A. Apoptosis is programmed cell death without inflammation; necrosis is
uncontrolled cell death with inflammation
B. Necrosis is programmed cell death; apoptosis is uncontrolled cell death
C. Both produce significant inflammatory responses
D. Both require ATP for execution
Answer: A
Rationale: Apoptosis is an energy-dependent, genetically programmed process of controlled cell
elimination that does not elicit an inflammatory response (cells shrink, form apoptotic bodies, and are
phagocytosed). Necrosis is an uncontrolled, accidental cell death caused by irreversible injury that
triggers a robust inflammatory response through release of intracellular contents into the extracellular
space.
Q3. A patient presents with chronic inflammation. Which cytokine is primarily responsible
for the acute-phase response in the liver?
A. Interleukin-2 (IL-2)
B. Interleukin-6 (IL-6)
C. Tumor necrosis factor-alpha (TNF-α)
D. Interferon-gamma (IFN-γ)
Answer: B
Rationale: IL-6 is the primary cytokine responsible for stimulating the liver to produce acute-phase
reactants such as C-reactive protein (CRP), fibrinogen, and serum amyloid A. TNF-α and IL-1 contribute
to the inflammatory cascade but IL-6 is the dominant driver of hepatic acute-phase protein synthesis.
Monitoring CRP levels clinically reflects IL-6–driven inflammation.
Q4. Which type of necrosis is characterized by soft, white, fish-flesh–like tissue appearance
and is commonly associated with tuberculosis?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
Answer: C
