SECTION 1: CELLULAR ADAPTATION, INJURY, AND
DEATH
Q1: Cellular Adaptation to Increased Workload
A patient with long-standing hypertension develops left ventricular hypertrophy. Which
of the following best describes the cellular mechanism responsible for this adaptation?
A. Atrophy due to decreased oxygen demand
B. Hypertrophy due to increased protein synthesis and sarcomere replication
[CORRECT]
C. Hyperplasia due to stem cell activation
D. Metaplasia due to chronic inflammation
Rationale:
Hypertrophy is an adaptive response to increased workload, characterized by enlargement
of individual cells (e.g., cardiomyocytes) due to increased protein synthesis and
sarcomere replication. This occurs in response to mechanical stress or neurohumoral
factors (e.g., angiotensin II, endothelin). Atrophy (A) involves cell shrinkage, hyperplasia (C) is
rare in cardiomyocytes, and metaplasia (D) involves reversible cell type replacement.
NURS 5315 Note: Hypertrophy is reversible if the stimulus is removed but can progress to
heart failure if sustained.
Q2: Compensatory Hyperplasia
,Which of the following is an example of compensatory hyperplasia?
A. Liver regeneration after partial hepatectomy [CORRECT]
B. Uterine enlargement during pregnancy
C. Prostate enlargement in older males
D. Callus formation after bone fracture
Rationale:
Compensatory hyperplasia occurs when tissue regenerates after injury (e.g., liver
regeneration post-hepatectomy). Uterine enlargement (B) is hormonal hyperplasia, prostate
enlargement (C) is pathological hyperplasia, and callus formation (D) is fibrous tissue
repair.
NURS 5315 Note: Hyperplasia is cell proliferation, distinct from hypertrophy (cell
enlargement).
Q3: Metaplasia in Chronic Smokers
A chronic smoker develops a change from ciliated columnar epithelium to stratified
squamous epithelium in the respiratory tract. This is an example of:
A. Dysplasia
B. Metaplasia [CORRECT]
C. Anaplasia
D. Hyperplasia
Rationale:
Metaplasia is a reversible replacement of one differentiated cell type with another, often
due to chronic irritation (e.g., smoking). Dysplasia (A) is disordered growth, anaplasia (C) is
loss of differentiation (malignancy), and hyperplasia (D) is cell proliferation.
NURS 5315 Note: Metaplasia is protective but can predispose to dysplasia or cancer (e.g.,
squamous cell carcinoma).
Q4: Dysplasia vs. Neoplasia
A Pap smear reveals cells with enlarged, hyperchromatic nuclei and disordered
stratification. This is most consistent with:
A. Metaplasia
B. Dysplasia [CORRECT]
C. Hyperplasia
D. Anaplasia
,Rationale:
Dysplasia is abnormal cell growth with atypia (e.g., cervical intraepithelial neoplasia).
Metaplasia (A) is cell type replacement, hyperplasia (C) is increased cell number, and
anaplasia (D) is undifferentiated malignant cells.
NURS 5315 Note: Dysplasia is premalignant and requires follow-up or intervention.
Q5: Free Radical Injury
Which of the following is the primary source of free radicals in cellular injury?
A. Lysosomal enzymes
B. Mitochondrial electron transport chain [CORRECT]
C. Ribosomal protein synthesis
D. Golgi apparatus glycosylation
Rationale:
The mitochondrial electron transport chain leaks superoxide (O₂⁻), which forms hydroxyl
radicals (·OH) via Fenton reactions. Free radicals damage lipids, proteins, and DNA, leading
to cell death or mutation.
NURS 5315 Note: Antioxidants (e.g., glutathione, vitamin E) neutralize free radicals.
Q6: Ischemia-Reperfusion Injury
Which of the following best explains the mechanism of ischemia-reperfusion injury?
A. Accumulation of lactic acid during ischemia
B. Generation of reactive oxygen species (ROS) upon reperfusion [CORRECT]
C. Increased ATP production during reperfusion
D. Activation of anti-apoptotic pathways
Rationale:
Reperfusion restores oxygen, leading to ROS burst from mitochondria and xanthine
oxidase , causing oxidative damage, inflammation, and cell death. Lactic acid (A) occurs
during ischemia, not reperfusion.
NURS 5315 Note: Reperfusion injury is a target for therapeutic antioxidants (e.g.,
N-acetylcysteine ).
Q7: Apoptosis vs. Necrosis
, A cell exposed to radiation undergoes programmed cell death with membrane blebbing,
chromatin condensation, and DNA fragmentation. This process is best described as:
A. Coagulative necrosis
B. Apoptosis [CORRECT]
C. Liquefactive necrosis
D. Caseous necrosis
Rationale:
Apoptosis is programmed cell death with energy-dependent caspase activation,
membrane blebbing, and DNA laddering. Necrosis (A, C, D) is uncontrolled cell death with
inflammation.
NURS 5315 Note: Apoptosis is physiologic (e.g., embryogenesis) or pathologic (e.g.,
radiation, chemotherapy).
Q8: Coagulative Necrosis
Coagulative necrosis is most commonly associated with:
A. Brain infarction
B. Myocardial infarction [CORRECT]
C. Pancreatic necrosis
D. Tuberculous granuloma
Rationale:
Coagulative necrosis occurs in solid organs (e.g., heart, kidney) due to protein denaturation,
preserving tissue architecture. Brain (A) undergoes liquefactive necrosis, pancreas (C) fat
necrosis, and TB (D) caseous necrosis.
NURS 5315 Note: Coagulative necrosis is reversible if perfusion is restored early.
Q9: Liquefactive Necrosis
Which condition is characterized by liquefactive necrosis?
A. Myocardial infarction
B. Cerebral infarction [CORRECT]
C. Pulmonary infarction
D. Renal infarction
Rationale:
Liquefactive necrosis occurs in brain infarcts due to hydrolytic enzyme release from
