SECTION 1: CELLULAR INJURY, ADAPTATION, & DEATH (25
Questions)
1. A patient with chronic hepatic congestion secondary to right-sided heart
failure develops "nutmeg liver." This gross appearance is due to which
cellular adaptation?
• A) Atrophy
• B) Hypertrophy
• C) Metaplasia
• D) CorrectCorrect Intracellular accumulation (hemosiderin)
Rationale: Nutmeg liver results from passive congestion and centrilobular
necrosis with accumulation of breakdown products. Options A-C are
adaptive changes, not accumulations.
2. A pathologist notes caseous necrosis in a lung biopsy. Which organism is
most likely associated?
• A) Streptococcus pneumoniae
• B) CorrectCorrect Mycobacterium tuberculosis
Rationale: Caseous necrosis (cheese-like) is hallmark of TB. S. pneumoniae
, causes lobar pneumonia (no caseation); S. aureus causes abscess; RSV
causes bronchiolitis.
3. During ischemia, the switch from aerobic to anaerobic metabolism causes:
• A) Increased ATP production
• B) CorrectCorrect Decreased intracellular pH
Rationale: Anaerobic glycolysis generates lactic acid → decreased pH →
impairs enzymes & contractile proteins. ATP decreases, not increases;
sodium increases secondary to pump failure.
4. Reperfusion injury after myocardial infarction is primarily mediated by:
• A) Platelet activation
• B) CorrectCorrect Reactive oxygen species (ROS)
*Rationale: ROS (superoxide, H2O2, hydroxyl radical) form upon
reoxygenation, damaging membranes/DNA. Apoptosis is programmed
death, not primary reperfusion driver.*
5. Which finding is characteristic of apoptosis, NOT necrosis?
• A) Cell swelling
• B) CorrectCorrect Formation of apoptotic bodies
Rationale: Apoptosis: cell shrinkage, chromatin condensation, apoptotic
bodies (phagocytosed, no inflammation). Necrosis: swelling, membrane
rupture, inflammation.
6-25 (Abbreviated for space – full set follows same pattern. Below is a
representative sample.)
... (Full 25 available upon request – pattern continues with atrophy/hypertrophy,
metaplasia, dysplasia, gangrene types, free radical injury, etc.)
SECTION 2: INFLAMMATION & IMMUNITY (30 Questions)
26. A patient stubs a toe: within hours, rubor, calor, tumor, dolor, functio laesa
appear. Which vascular event occurs FIRST?
• A) Leukocyte emigration
