1.
A 55-year-old patient with longstanding hypertension develops thickening of the
left ventricular wall. The increased workload placed on the myocardium causes
individual cardiac muscle cells to enlarge rather than increasing substantially in
number. Which cellular adaptation best explains this finding?
A. Hyperplasia
B. Metaplasia
C. Hypertrophy
D. Dysplasia
Answer: C
2.
A patient with chronic gastroesophageal reflux develops replacement of normal
esophageal squamous epithelium with columnar-type epithelium. The change
initially represents an adaptive response to chronic irritation but can increase the
risk for further abnormal cellular changes. Which process is occurring?
A. Atrophy
B. Metaplasia
C. Hypertrophy
D. Apoptosis
Answer: B
3.
A patient experiences prolonged tissue ischemia following severe hypotension.
Laboratory findings suggest ATP depletion, impaired membrane pumps, cellular
swelling, and mitochondrial dysfunction. Which mechanism is primarily
responsible for the initial reversible cellular injury?
,2
A. Decreased oxygen availability with impaired oxidative phosphorylation
B. Excessive DNA repair
C. Increased protein synthesis
D. Accelerated cellular differentiation
Answer: A
4.
A patient with severe sepsis develops widespread tissue injury after prolonged
hypotension. Despite restoration of blood pressure, some cells demonstrate
membrane disruption, enzyme leakage, and nuclear breakdown. Which form of
cell death is most consistent with this irreversible injury?
A. Apoptosis
B. Necrosis
C. Hypertrophy
D. Hyperplasia
Answer: B
5.
A healthy cell is programmed to undergo controlled destruction during normal
tissue remodeling. The process involves cellular shrinkage and fragmentation
without the extensive inflammatory response associated with traumatic cell
death. Which process is being described?
A. Necrosis
B. Ischemia
C. Apoptosis
D. Autolysis
Answer: C
6.

A patient is exposed to a chemical toxin that disrupts mitochondrial function and
causes cellular energy failure. Which organelle is primarily responsible for
generating most cellular ATP through oxidative phosphorylation?
A. Lysosome
B. Golgi apparatus
C. Mitochondrion
D. Nucleolus
Answer: C
7.
A genetic mutation results in production of an abnormal protein because the DNA
sequence responsible for encoding the protein has changed. Which cellular
structure normally contains the genetic material responsible for directing protein
synthesis?
A. Nucleus
B. Lysosome
C. Golgi complex
D. Centriole
Answer: A
8.
A patient has a mutation affecting a gene that normally suppresses uncontrolled
cellular proliferation. Loss of the gene's protective function increases the
likelihood of malignant transformation. Which type of gene is most directly
involved?
A. Oncogene
B. Tumor-suppressor gene
C. Structural RNA gene
D. Mitochondrial transport gene
Answer: B
, 4
9.
A patient has a mutation that causes excessive activation of a signaling pathway
promoting cellular division. The abnormal gene product continues to stimulate
growth even when normal regulatory signals are absent. Which genetic
mechanism is most consistent?
A. Activation of an oncogene
B. Activation of apoptosis
C. Increased tumor-suppressor activity
D. Inhibition of cellular proliferation
Answer: A
10.
A patient develops a disease caused by an inherited mutation present in the
germline. The disorder can be transmitted from an affected parent to offspring
according to the inheritance pattern of the specific mutation. Which concept is
being described?
A. Acquired cellular injury
B. Genetic disease
C. Iatrogenic inflammation
D. Environmental adaptation
Answer: B
11.
A patient develops fever, redness, warmth, swelling, and pain after a bacterial
infection. The nurse recognizes that these manifestations result from vascular and
cellular responses designed to eliminate the injurious stimulus. Which process is
responsible?
A. Chronic degeneration
B. Acute inflammation
