1. Cellular Adaptation, Injury, and Death (Q1–Q10)
🟢 Q1. A client’s bronchial epithelium changes from ciliated columnar to stratified squamous after years
of smoking. Which cellular adaptation does the nurse identify?
A) Atrophy
B) Hypertrophy
🔴🔴 C) Metaplasia
D) Dysplasia
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one mature cell type with another better able to
survive stress. Atrophy is shrinkage; hypertrophy is enlargement; dysplasia is disordered growth without
a change in cell type.
🟢 Q2. A client has a cerebral infarct. Which type of necrosis is most likely present in the affected brain
tissue?
A) Coagulative necrosis
🔴🔴 B) Liquefactive necrosis
C) Caseous necrosis
D) Fat necrosis
Correct Answer: B
Rationale: Liquefactive necrosis occurs in brain infarcts because digestive enzymes and lack of structural
support cause dead tissue to become soft and liquid. Coagulative necrosis is typical in heart, kidney, and
spleen.
🟢 Q3. Which statement best describes apoptosis?
🔴🔴 A) Programmed cell death that does not trigger inflammation
B) Uncontrolled cell death that always causes inflammation
C) Death of a group of cells due to ischemia
D) Death caused by bacterial toxins only
Correct Answer: A
Rationale: Apoptosis is energy-dependent programmed cell death that removes unwanted or damaged
cells without inciting inflammation. Necrosis is uncontrolled and typically triggers inflammation.
, 🟢 Q4. During severe hypoxia, which mechanism is primarily responsible for cell death?
A) Accumulation of misfolded proteins
🔴🔴 B) Depletion of ATP leading to failure of the sodium–potassium pump
C) Activation of apoptotic pathways by p53
D) Excessive autophagy
Correct Answer: B
Rationale: Severe hypoxia halts oxidative phosphorylation, causing ATP depletion. Without ATP, the
Na⁺/K⁺ ATPase pump fails, leading to cellular swelling, calcium influx, and eventual necrosis.
🟢 Q5. A patient has prolonged ischemia to a limb. Which intracellular change is most characteristic of
reversible cell injury?
A) Nuclear fragmentation
B) Plasma membrane rupture
🔴🔴 C) Cellular swelling
D) Mitochondrial calcification
Correct Answer: C
Rationale: Cellular swelling due to ATP depletion and failure of ion pumps is the hallmark of reversible
cell injury. Nuclear fragmentation and membrane rupture indicate irreversible injury.
🟢 Q6. Which cellular adaptation is characterized by a decrease in cell size and function due to decreased
workload or diminished blood supply?
A) Hypertrophy
B) Hyperplasia
🔴🔴 C) Atrophy
D) Metaplasia
Correct Answer: C
Rationale: Atrophy is the reduction in cell size after normal maturity, often caused by decreased
workload, loss of innervation, diminished blood supply, or inadequate nutrition.
🟢 Q7. Free radicals cause cell damage primarily by:
A) Stabilizing chemical bonds
🔴🔴 B) Damaging cell membrane lipids
C) Enhancing ATP production
D) Increasing protein synthesis
Correct Answer: B
Rationale: Free radicals cause oxidative damage to cell membrane lipids, leading to membrane
instability and cell injury.
🟢 Q8. What is the primary mechanism of ischemia–reperfusion injury?
A) Increased ATP production
🔴🔴 B) Oxidative stress from reactive oxygen species
C) Decreased inflammatory response
D) Enhanced cellular repair
Correct Answer: B
Rationale: Reperfusion after ischemia generates reactive oxygen species, causing oxidative damage and
further tissue injury.
