1. Which of the following cellular adaptations is typically
considered reversible and represents a response to increased
functional demand or hormonal stimulation?
• A. Metaplasia
• B. Hypertrophy
• C. Dysplasia
• D. Necrosis
• Answer: B
• Rationale: Hypertrophy is an increase in the size of cells
resulting in an increased size of the organ, driven by
increased functional demand or hormonal stimulation. It is
a reversible adaptation, whereas necrosis is irreversible cell
death, and dysplasia is disordered growth.
2. Ischemia-reperfusion injury is primarily mediated by which
of the following cellular mechanisms?
• A. Depletion of intracellular ATP
• B. Generation of reactive oxygen species (ROS)
• C. Intracellular accumulation of triglycerides
, • D. Decreased cytosolic calcium concentration
• Answer: B
• Rationale: Reperfusion of ischemic tissue paradoxically
exacerbates cell injury through the massive generation of
reactive oxygen species (free radicals) from dysfunctional
mitochondria and inflammatory cells, which damage lipids,
proteins, and DNA.
3. Coagulative necrosis is most commonly caused by ischemia
in which of the following organs?
• A. Brain
• B. Heart
• C. Pancreas
• D. Lungs
• Answer: B
• Rationale: Coagulative necrosis results from
hypoxia/ischemia and is characteristic of infarcts in organs
such as the heart, kidneys, and spleen. The brain
undergoes liquefactive necrosis due to high lipid content
and abundant hydrolytic enzymes.
4. Apoptosis differs from necrosis in that apoptosis:
• A. Involves severe cellular swelling and membrane rupture
, • B. Triggers a prominent adjacent inflammatory response
• C. Is an energy-dependent, genetically programmed cell
death
• D. Always occurs as a pathological consequence of acute
toxins
• Answer: C
• Rationale: Apoptosis is a regulated, energy-dependent
(ATP-requiring) process of programmed cell death
characterized by cell shrinkage, chromatin condensation,
and formation of apoptotic bodies without triggering a
localized inflammatory response.
5. Accumulation of abnormal amounts of intracellular
triglycerides in the liver is most commonly referred to as:
• A. Hydropic degeneration
• B. Steatosis (fatty change)
• C. Amyloidosis
• D. Dystrophic calcification
• Answer: B
• Rationale: Steatosis (fatty change) is the abnormal
accumulation of triglycerides within parenchymal cells,
most frequently seen in the liver due to toxins (like
alcohol), malnutrition, or metabolic syndrome.
