SECTION 1: CELL INJURY, ADAPTATION & DEATH
1. Which cellular adaptation involves an increase in the number of cells in a
tissue or organ in response to increased demand?
A. Atrophy
B. Hypertrophy
C. Metaplasia
D. Dysplasia
E. Hyperplasia
✓ Correct Answer: E. Hyperplasia
EXPERT RATIONALE: Hyperplasia is an increase in the number of cells resulting in
increased organ or tissue size. It is a reversible adaptation occurring in response to
hormonal stimulation or chronic irritation, and differs from hypertrophy, which is
an increase in cell size.
2. A patient with chronic hypertension develops left ventricular wall
thickening. This is an example of which cellular adaptation?
,A. Hyperplasia
B. Metaplasia
C. Atrophy
D. Hypertrophy
E. Dysplasia
✓ Correct Answer: D. Hypertrophy
EXPERT RATIONALE: Hypertrophy is an increase in cell size leading to increased
organ size. The left ventricle undergoes hypertrophy in response to increased
afterload from hypertension, since cardiac myocytes cannot undergo significant
hyperplasia.
3. Which type of cell death is characterized by cell swelling, membrane
rupture, and inflammation?
A. Apoptosis
B. Autophagy
C. Anoikis
D. Necrosis
E. Pyroptosis
✓ Correct Answer: D. Necrosis
EXPERT RATIONALE: Necrosis is pathologic cell death characterized by cell swelling,
organelle dysfunction, membrane rupture, and release of cellular contents that
trigger inflammation. This distinguishes it from apoptosis, which is programmed
and does not incite an inflammatory response.
4. Apoptosis differs from necrosis in that apoptosis:
A. Results in cell swelling
,B. Triggers an inflammatory response
C. Involves membrane rupture
D. Is an energy-dependent, programmed process
E. Causes release of lysosomal enzymes
✓ Correct Answer: D. Is an energy-dependent, programmed process
EXPERT RATIONALE: Apoptosis is programmed cell death requiring ATP and
involving caspase activation. It results in cell shrinkage, chromatin condensation,
and formation of apoptotic bodies that are phagocytosed without triggering
inflammation. These features clearly distinguish it from necrosis.
5. Which type of necrosis is commonly seen in myocardial infarction?
A. Liquefactive necrosis
B. Caseous necrosis
C. Fat necrosis
D. Coagulative necrosis
E. Fibrinoid necrosis
✓ Correct Answer: D. Coagulative necrosis
EXPERT RATIONALE: Coagulative necrosis is the most common type of necrosis
and is typically seen in myocardial infarction and other ischemic injuries to solid
organs (except the brain). The tissue architecture is preserved but cells are dead,
giving a ghost-like appearance on histology.
6. Liquefactive necrosis is characteristically seen in which of the following
conditions?
A. Myocardial infarction
B. Tuberculosis
, C. Pancreatitis
D. Brain infarction
E. Fat tissue injury
✓ Correct Answer: D. Brain infarction
EXPERT RATIONALE: Liquefactive necrosis occurs when enzymes completely digest
dead tissue, forming a liquid mass. This is characteristic of brain infarctions due to
the high lipid content and enzyme-rich environment. It is also seen in bacterial
abscesses where neutrophil enzymes digest tissue.
7. Caseous necrosis is most commonly associated with which infectious
organism?
A. Staphylococcus aureus
B. Streptococcus pneumoniae
C. Histoplasma capsulatum
D. Mycobacterium tuberculosis
E. Aspergillus fumigatus
✓ Correct Answer: D. Mycobacterium tuberculosis
EXPERT RATIONALE: Caseous necrosis has a cheese-like gross appearance and is
most characteristically associated with tuberculosis. It is a form of coagulative
necrosis with liquefactive elements surrounded by a granulomatous reaction of
epithelioid macrophages, Langhans giant cells, and lymphocytes.
8. A patient with Duchenne muscular dystrophy has progressive muscle
wasting. This is primarily an example of:
A. Hypertrophy
B. Hyperplasia
