Section 1: Cellular Adaptation, Injury, & Neoplasia
(Questions 1–25)
Question 1
A 62-year-old male with a 45-pack-year smoking history
presents with a chronic cough and hemoptysis. A bronchial
biopsy reveals that the normal ciliated columnar epithelium has
been replaced by stratified squamous epithelium. Which
cellular adaptation best describes this finding, and what is its
clinical significance?
A. Hyperplasia – it is a reversible increase in cell number with no

malignant potential
B. Metaplasia – it is a reversible substitution of one cell type for
another that increases the risk of malignancy
C. Dysplasia – it is an irreversible premalignant change requiring
immediate resection
D. Anaplasia – it indicates the presence of an aggressive
malignant tumor
CORRECT ANSWER: B
RATIONALE: Metaplasia is a reversible substitution of one
differentiated cell type for another that is more resistant to
chronic stress. In smokers, the respiratory epithelium
undergoes squamous metaplasia as an adaptive response to
chronic irritation. However, this metaplastic epithelium has a
higher risk of subsequent dysplastic transformation and
malignancy.
Question 2
A researcher is studying a population of cells that have
undergone irreversible cell injury. Which of the following
morphological changes is the earliest and most reliable
indicator that the cells have passed the point of no return?
A. Cellular swelling and loss of microvilli
B. Mitochondrial swelling and dilation of the endoplasmic
reticulum
C. Severe mitochondrial damage with calcium influx and
plasma membrane disruption
D. Nuclear pyknosis and karyorrhexis
CORRECT ANSWER: C

RATIONALE: Irreversible cell injury is characterized by severe
mitochondrial dysfunction with calcium accumulation,
extensive membrane damage, and lysosomal rupture. Cellular
swelling and mitochondrial changes occur in reversible injury,
while nuclear changes are later manifestations.
Question 3
A 55-year-old female with chronic gastroesophageal reflux
disease undergoes an upper endoscopy. Biopsy of the lower
esophagus reveals columnar epithelium with goblet cells
replacing the normal stratified squamous epithelium. This
finding is best described as:
A. Barrett esophagus, which is a form of metaplasia that
predisposes to adenocarcinoma
B. Barrett esophagus, which is a form of dysplasia that requires
immediate surgical resection
C. Peptic ulcer disease, which is caused by H. pylori infection
D. Eosinophilic esophagitis, which is an allergic inflammatory
condition
CORRECT ANSWER: A
RATIONALE: Barrett esophagus is a metaplastic change in
which the normal squamous epithelium of the lower esophagus
is replaced by specialized columnar epithelium with goblet
cells. This adaptive response to chronic acid exposure
significantly increases the risk of esophageal adenocarcinoma.
Question 4
A 48-year-old female with a strong family history of breast
, Page 4 of 79
cancer undergoes genetic testing and is found to have a BRCA1
mutation. This mutation increases her risk of breast and ovarian
cancer because BRCA1 is involved in which critical cellular
process?
A. Apoptosis regulation through the BCL-2 pathway
B. Homologous recombination repair of double-strand DNA
breaks
C. Cell cycle checkpoint activation at the G1/S transition
D. Inhibition of angiogenesis through vascular endothelial
growth factor (VEGF) suppression
CORRECT ANSWER: B
RATIONALE: BRCA1 is a tumor suppressor gene essential for
homologous recombination repair of double-strand DNA
breaks. Loss of this function leads to genomic instability and
significantly increased cancer susceptibility.
Question 5
A 70-year-old patient with severe protein-calorie malnutrition
develops muscle wasting and generalized weakness. The
cellular process primarily responsible for this finding is:
A. Hypertrophy due to increased protein synthesis
B. Hyperplasia due to increased cell division
C. Atrophy due to decreased protein synthesis and increased
protein degradation
D. Metaplasia due to replacement of muscle cells with adipose
tissue
CORRECT ANSWER: C
