Cellular Biology, Adaptation, Injury & Neoplasia
Q1: A 68-year-old male with chronic heart failure has enlarged cardiac muscle cells with
increased DNA content. The nurse practitioner recognizes this cellular adaptation as:
A. Atrophy from disuse
B. Hypertrophy due to increased workload [CORRECT]
C. Hyperplasia from hormonal stimulation
D. Metaplasia from chronic irritation
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size (not number) in response to increased
workload, resulting in enlarged cells with more DNA and organelles. The heart muscle
hypertrophies to compensate for increased afterload in heart failure. Atrophy (A) is
decrease in size, hyperplasia (C) is increase in cell number, and metaplasia (D) is
change in cell type.
,Q2: A patient with chronic gastroesophageal reflux develops Barrett's esophagus. This
represents which type of cellular adaptation?
A. Dysplasia
B. Metaplasia [CORRECT]
C. Anaplasia
D. Hypertrophy
Correct Answer: B
Rationale: Barrett's esophagus is metaplasia—replacement of normal squamous
epithelium with columnar epithelium in response to chronic acid exposure. This is a
reversible adaptive change. Dysplasia (A) is disordered growth, anaplasia (C) is loss of
differentiation (malignant), and hypertrophy (D) is increased cell size.
Q3: A biopsy shows cells with abnormal size, shape, and organization, but the changes
don't extend through the full epithelial thickness. The pathologist reports:
A. Carcinoma in situ
B. Severe dysplasia [CORRECT]
C. Benign hyperplasia
D. Normal metaplasia
Correct Answer: B
Rationale: Dysplasia refers to disordered, dysfunctional cellular growth with abnormal
size, shape, and organization. "Severe" indicates significant abnormality without
,full-thickness involvement (which would be carcinoma in situ, A). It's not merely
hyperplasia (C—increased number) or normal metaplasia (D—orderly type change).
Q4: In hypoxic cell injury, which organelle swells first due to failure of the
sodium-potassium pump?
A. Nucleus
B. Mitochondrion
C. Endoplasmic reticulum
D. Lysosome
Correct Answer: C
Rationale: The endoplasmic reticulum swells first in reversible hypoxic injury due to loss
of ionic gradients and water influx. Mitochondria (B) swell with more severe injury, and
lysosomes (D) rupture in irreversible injury. Nuclear changes (A) occur later.
Q5: A patient suffers myocardial infarction. The necrotic tissue appears firm and
preserves cellular outlines microscopically. This is:
A. Liquefactive necrosis
B. Coagulative necrosis [CORRECT]
C. Caseous necrosis
D. Fat necrosis
Correct Answer: B
, Rationale: Coagulative necrosis (typical of ischemia in solid organs like heart, kidney,
spleen) preserves tissue architecture initially due to denaturation of structural proteins,
appearing firm and pale. Liquefactive (A) occurs in brain and abscesses, caseous (C) in
tuberculosis, and fat necrosis (D) in pancreatitis/breast trauma.
Q6: A patient with streptococcal infection develops brain abscess. The necrotic center
appears soft and liquid. This represents:
A. Coagulative necrosis
B. Liquefactive necrosis [CORRECT]
C. Gangrenous necrosis
D. Apoptosis
Correct Answer: B
Rationale: Liquefactive necrosis occurs when enzymatic digestion (from bacterial or
tissue enzymes) liquefies tissue, creating pus or soft centers—characteristic of brain
infarcts and abscesses. Coagulative (A) preserves structure, gangrenous (C) refers to
ischemic tissue death (often coagulative or wet), and apoptosis (D) is programmed cell
death without inflammation.
Q7: A patient with tuberculosis has necrotic tissue that appears soft, white, and
"cheese-like." This is:
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis [CORRECT]
