, SECTION 1: Cellular, Genetic & Developmental Pathophysiology
Q1. A 45-year-old patient with chronic hypertension develops left-ventricular hypertrophy. The nurse practitioner explains that the
myocardial cells have enlarged in response to increased workload. This cellular change is best classified as which adaptive
process?
A. Hypertrophy due to increased functional demand
B. Atrophy resulting from disuse
C. Hyperplasia from hormonal stimulation
D. Metaplasia converting one cell type to another
Correct Answer: A
Rationale: Hypertrophy is the increase in cell size in response to increased workload, as seen in pressure-overload states such as hypertension.
Atrophy is size decrease, hyperplasia is cell-number increase, and metaplasia is replacement by a different cell type.
Q2. A pathologist examines tissue from a smoker’s bronchus and notes replacement of normal ciliated columnar epithelium by
stratified squamous epithelium. Which process has occurred?
A. Dysplasia with disordered growth
B. Neoplasia with uncontrolled proliferation
C. Metaplasia as an adaptive response to chronic irritation
D. Hypertrophy of the existing epithelium
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one differentiated cell type by another, commonly seen in the respiratory tract of smokers. It
is adaptive but may progress to dysplasia if the stimulus persists.
Q3. A patient experiences acute ischemia of the lower leg after arterial occlusion. After several hours the tissue shows irreversible
injury with membrane rupture and nuclear dissolution. Which form of cell death has occurred?
A. Apoptosis with orderly DNA fragmentation
B. Necrosis characterized by loss of membrane integrity and inflammation
C. Autophagy with lysosomal degradation of organelles
D. Senescence with permanent cell-cycle arrest
Correct Answer: B
Rationale: Necrosis is unregulated cell death resulting from severe injury; it features membrane breakdown and typically elicits inflammation.
Apoptosis is programmed and non-inflammatory.
Q4. Laboratory analysis of a tumor reveals cells with high nuclear-to-cytoplasmic ratio, prominent nucleoli, and frequent mitotic
figures. These features are most consistent with:
A. Benign hyperplasia
B. Reversible cellular adaptation
C. Physiologic hypertrophy
D. Malignant neoplasia with anaplasia
Correct Answer: D
Rationale: Anaplasia (lack of differentiation) with high N/C ratio, prominent nucleoli, and increased mitoses is a hallmark of malignant neoplasms.
Q5. A newborn is diagnosed with cystic fibrosis caused by a mutation in the CFTR gene. The mutation leads to defective chloride
transport. This disorder is inherited in which pattern?
A. Autosomal dominant with incomplete penetrance
B. Autosomal recessive requiring two mutant alleles
C. X-linked recessive affecting primarily males
D. Mitochondrial inheritance from the mother only
Correct Answer: B
Rationale: Cystic fibrosis is a classic autosomal-recessive disorder; affected individuals must inherit two defective CFTR alleles.

, Q6. During embryonic development, failure of the neural tube to close completely results in spina bifida. This congenital anomaly is
most closely associated with deficiency of which nutrient during early pregnancy?
A. Folic acid (folate)
B. Vitamin A
C. Vitamin D
D. Iron
Correct Answer: A
Rationale: Adequate maternal folate intake is critical for neural-tube closure; deficiency is a major risk factor for spina bifida and anencephaly.
Q7. A cell exposed to low-level stress activates the unfolded-protein response and increases chaperone production. If the stress is
prolonged and unresolved, which outcome becomes more likely?
A. Successful adaptation and continued normal function
B. Immediate necrosis without signaling
C. Apoptosis triggered by persistent endoplasmic-reticulum stress
D. Conversion to a stem-cell phenotype
Correct Answer: C
Rationale: Unresolved ER stress shifts the unfolded-protein response from adaptive to pro-apoptotic signaling, leading to programmed cell death.
Q8. A patient with longstanding GERD develops Barrett esophagus. Columnar epithelium replaces the normal squamous lining of
the distal esophagus. This change increases the risk of which subsequent process?
A. Simple hyperplasia without further progression
B. Complete reversal to normal squamous epithelium in all cases
C. Immediate invasive carcinoma without intermediate steps
D. Dysplasia and potential adenocarcinoma
Correct Answer: D
Rationale: Metaplastic Barrett epithelium is a precursor that can progress through dysplasia to esophageal adenocarcinoma if the injurious
stimulus continues.
Q9. Free-radical injury is implicated in reperfusion of ischemic tissue. Which cellular component is particularly vulnerable to lipid
peroxidation by reactive oxygen species?
A. Polyunsaturated fatty acids in membrane phospholipids
B. Nuclear DNA exclusively
C. Mitochondrial matrix proteins only
D. Cytoskeletal intermediate filaments exclusively
Correct Answer: A
Rationale: Reactive oxygen species attack polyunsaturated fatty acids in membranes, producing lipid peroxidation that compromises membrane
integrity.
Q10. A 60-year-old patient has a slowly growing mass that is well-circumscribed, encapsulated, and composed of cells resembling
the tissue of origin. These features most strongly suggest:
A. Malignant carcinoma with metastatic potential
B. Benign neoplasm
C. High-grade sarcoma
D. Inflammatory pseudotumor only
Correct Answer: B
Rationale: Benign neoplasms are typically slow-growing, well-demarcated or encapsulated, and histologically similar to the parent tissue.
Q11. In the process of carcinogenesis, an initiating mutation is fixed in the DNA of a cell. Subsequent promoting stimuli cause
clonal expansion. Which statement best describes the initiator?
A. It is reversible and does not alter DNA
B. It alone is sufficient to produce a malignant tumor
C. It produces a permanent genetic change that is necessary but not sufficient for tumor formation
D. It acts only on already-transformed cells
Correct Answer: C
Rationale: Initiators cause irreversible DNA mutations; promoters then drive proliferation of the initiated cells. Both steps are required for most
cancers.
