SECTION 1: CELLULAR ADAPTATION, INJURY &
NEOPLASIA (Questions 1–20)
Question 1
A patient with chronic hypertension has an enlarged
heart. This increase in muscle mass is primarily due to
which cellular adaptation?
A) Hyperplasia
B) Metaplasia
C) Hypertrophy
D) Dysplasia
Answer: C) Hypertrophy
Rationale: Hypertrophy is an increase in the size of
cells, leading to organ enlargement. Cardiac muscle cells
are terminally differentiated and cannot divide
(hyperplasia), so they adapt to increased workload
(afterload) by increasing in size to generate greater
contractile force.
,Question 2
The irreversible point in cellular injury where cell death is
inevitable, even if the stressor is removed, is known as
the:
A) Point of no return
B) Cellular apoptosis threshold
C) Necrotic point
D) Ischemic threshold
Answer: A) Point of no return
Rationale: The "point of no return" describes the stage
where mitochondrial damage becomes so severe that
ATP production ceases entirely, leading to irreversible
membrane and DNA damage. Once this point is reached,
cell death is inevitable regardless of intervention.
Question 3
Which of the following is a characteristic feature of
apoptosis?
A) Elicits a significant inflammatory response
B) Results in cellular swelling and rupture
C) Involves organized cell shrinkage and fragmentation
D) Is always a pathological process
,Answer: C) Involves organized cell shrinkage and
fragmentation
Rationale: Apoptosis is programmed, controlled cell
death that involves cell shrinkage, chromatin
condensation, nuclear fragmentation, and formation of
apoptotic bodies that are phagocytosed without eliciting
inflammation. Necrosis is characterized by cell swelling,
rupture, and inflammation.
Question 4
A client who smokes has a change in the bronchial
epithelium from ciliated columnar to stratified squamous.
This is an example of:
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Answer: D) Metaplasia
Rationale: Metaplasia is a reversible change where one
differentiated cell type is replaced by another, often in
response to chronic irritation. The bronchial lining
changes to a more protective (but less functional)
squamous epithelium in response to chronic smoke
exposure.
, Question 5
Ischemia-reperfusion injury causes additional cellular
damage primarily due to:
A) Immediate restoration of ATP levels
B) Influx of calcium and generation of oxygen-free
radicals
C) Rapid normalization of pH
D) Decreased inflammatory response
Answer: B) Influx of calcium and generation of
oxygen-free radicals
Rationale: When blood flow is restored after ischemia,
the sudden influx of oxygen leads to the generation of
reactive oxygen species (free radicals) and a massive
calcium influx into cells, which causes additional
mitochondrial damage and cell death beyond the initial
ischemic injury.
Question 6
Which type of necrosis preserves tissue architecture for
several days and is characteristic of solid organs such as
the kidney, heart, and liver?
A) Liquefactive necrosis
B) Coagulative necrosis
