Section 1: Cellular & Molecular Pathophysiology
Cellular injury, adaptation, necrosis, apoptosis, accumulations — 15 questions
Q1: A 68-year-old male with chronic heart failure has an enlarged heart on chest X-ray. The
cardiomyocyte enlargement responsible for this finding is BEST described as:
A. Hyperplasia, an increase in cell number in response to hormonal stimulation.
B. Hypertrophy, an increase in cell size in response to increased workload or mechanical stress, driven
by augmented protein synthesis and assembly of additional sarcomeres. *[CORRECT]*
C. Metaplasia, the reversible replacement of one differentiated cell type by another.
D. Dysplasia, disordered growth showing cellular atypia.
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size (not number) in non-dividing cells such as cardiac myocytes; it occurs
in response to pressure or volume overload via mechanosensors and growth-factor signaling that upregulate sarcomeric
protein synthesis. Hyperplasia requires cells capable of division, which adult cardiomyocytes essentially cannot do;
metaplasia and dysplasia are altered-differentiation processes (Walden NURS 6501 Module 1: Cellular Adaptation).
Q2: A 55-year-old chronic smoker has squamous metaplasia of the bronchial epithelium. The
pathophysiologic consequence of greatest clinical concern is:
A. Immediate loss of ciliary function causing pneumonia.
B. Persistent metaplasia may progress to dysplasia and eventually squamous cell carcinoma if the
injurious stimulus (smoking) continues, because the altered differentiation creates a fertile field for
additional genetic hits. *[CORRECT]*
C. Acute bronchospasm and wheezing within 24 hours.
D. Reversible resolution within days of smoking cessation without residual risk.
Correct Answer: B
Rationale: Squamous metaplasia of bronchial epithelium is an adaptive substitution of stratified squamous for ciliated
pseudostratified columnar epithelium that better tolerates smoke. If the stimulus persists, the metaplastic field can
progress through dysplasia to squamous cell carcinoma via accumulated mutations (field cancerization). The change is
potentially reversible early but carries long-term malignant risk (Walden NURS 6501 Module 1: Cellular Adaptation &
Neoplasia).

Q3: A biopsy of a cervical lesion reports 'moderate dysplasia (CIN II).' The defining feature that
distinguishes dysplasia from carcinoma in situ is:
A. Dysplasia shows cellular atypia confined to the epithelium without crossing the basement
membrane, whereas carcinoma in situ also remains confined but shows full-thickness atypia;
invasion through the basement membrane defines invasive carcinoma. *[CORRECT]*
B. Dysplasia has already breached the basement membrane.
C. Dysplasia involves only the lamina propria.
D. Dysplasia is irreversible even after stimulus removal.
Correct Answer: A
Rationale: Dysplasia is disordered growth with atypia that is confined to the epithelial layer and does not cross the
basement membrane. Carcinoma in situ represents full-thickness epithelial atypia also confined by the basement
membrane; invasion through the basement membrane into underlying stroma defines invasive carcinoma. Dysplasia is
often reversible if the injurious stimulus is removed (Walden NURS 6501 Module 1: Cellular Adaptation & Neoplasia).
Q4: A patient suffers a myocardial infarction. Six hours later, histologic examination of the infarcted
myocardium would MOST likely show:
A. Coagulative necrosis, characterized by preservation of tissue architecture with loss of nuclei and
eosinophilic cytoplasm, typical of ischemic injury in most solid organs. *[CORRECT]*
B. Liquefactive necrosis, with complete enzymatic dissolution of tissue, as seen in brain infarcts.
C. Caseous necrosis, with cheese-like amorphous debris enclosed by granulomatous inflammation.
D. Fat necrosis, with saponification of adipose tissue.
Correct Answer: A
Rationale: Coagulative necrosis is the pattern of ischemic cell death in most solid tissues (heart, kidney, liver, spleen)
where protein denaturation preserves tissue architecture. Liquefactive necrosis occurs in the brain (due to high lipid
content and lack of stroma) and in bacterial abscesses; caseous necrosis is characteristic of tuberculosis; fat necrosis
occurs in pancreatic and breast tissue (Walden NURS 6501 Module 1: Cell Injury & Death).
Q5: Compared with necrosis, apoptosis is BEST described as:
A. A pathologic, unregulated process that always elicits a strong inflammatory response.
B. A highly regulated, energy-dependent program of cell suicide executed by caspases that produces
cellular fragments (apoptotic bodies) rapidly cleared by phagocytes without significant inflammation.
*[CORRECT]*
C. Identical to coagulative necrosis histologically.
D. A process triggered exclusively by external toxins.
Correct Answer: B
Rationale: Apoptosis is programmed, energy-dependent cell death mediated by initiator and executioner caspases
(intrinsic mitochondrial pathway with cytochrome c release, or extrinsic death-receptor pathway). It produces
membrane-bound apoptotic bodies cleared by macrophages without inflammation, in contrast to necrosis which is
unregulated, lytic, and inflammatory (Walden NURS 6501 Module 1: Cell Death Mechanisms).
