Q1 Question 1 of 75
A 58-year-old heavy smoker has squamous metaplasia of the bronchial epithelium on biopsy. The
pathologist explains that this change represents a reversible adaptive response. Which mechanism best
describes this adaptation?
A. Accumulation of lipid droplets in the cytoplasm
B. Increase in cell number in response to hormones
C. Replacement of one mature cell type with another more resistant to stress
D. Decrease in cell size to reduce oxygen demand
Correct Answer: C
Rationale:
Metaplasia is the reversible replacement of one differentiated cell type with another better able to withstand
chronic irritation, such as squamous cells replacing respiratory epithelium in smokers. Atrophy is decreased cell
size; hyperplasia is increased cell number; fatty change involves lipid accumulation.
Q2 Question 2 of 75
A 70-year-old bedridden patient loses 30% of muscle mass over two months. Microscopy shows
decreased cell size without cell death. Which cellular adaptation is occurring?
A. Atrophy
B. Dysplasia
C. Hypertrophy
D. Anaplasia
Correct Answer: A
Rationale:
Disuse atrophy is the reduction in cell size and organelle content due to decreased workload or trophic signals,
as seen in immobilized muscles. Hypertrophy is increased cell size; dysplasia is disordered growth; anaplasia is
loss of differentiation seen in cancer.

Q3 Question 3 of 75
A 25-year-old bodybuilder shows enlarged muscle fibers with increased contractile proteins after years
of training. Which cellular adaptation explains this finding?
A. Metaplasia
B. Hypertrophy
C. Hyperplasia
D. Neoplasia
Correct Answer: B
Rationale:
Hypertrophy is an increase in cell size, exemplified by skeletal muscle enlargement from resistance training
through added sarcomeres and contractile proteins. Hyperplasia is increased cell number; metaplasia and
neoplasia involve cell type change and abnormal growth respectively.
Q4 Question 4 of 75
A 32-year-old pregnant woman has an enlarged uterus. Histology reveals both larger and more
numerous smooth muscle cells. Which combined adaptations are present?
A. Hypertrophy and hyperplasia
B. Dysplasia and anaplasia
C. Atrophy and metaplasia
D. Apoptosis and necrosis
Correct Answer: A
Rationale:
The gravid uterus undergoes both hypertrophy and hyperplasia of smooth muscle cells due to hormonal
stimulation, dramatically increasing organ mass. The other options describe pathologic or cell-death processes
rather than physiologic growth.

Q5 Question 5 of 75
A 60-year-old with chronic gastric reflux has intestinal-type columnar epithelium replacing the normal
squamous epithelium at the gastroesophageal junction. Which term best describes this finding?
A. Barrett esophagus (intestinal metaplasia)
B. Esophageal varices
C. Peptic ulceration
D. Squamous cell carcinoma
Correct Answer: A
Rationale:
Barrett esophagus is intestinal metaplasia of the distal esophageal squamous epithelium due to chronic acid
exposure, predisposing to adenocarcinoma. The other options describe different pathologies of the esophagus.
Q6 Question 6 of 75
A biopsy from a 55-year-old with chronic cervical inflammation shows disordered, pleomorphic cells
confined to the epithelium without basement membrane invasion. Which term best describes this
lesion?
A. Invasive carcinoma
B. Simple metaplasia
C. Benign hyperplasia
D. Carcinoma in situ
Correct Answer: D
Rationale:
Carcinoma in situ is severe dysplasia involving the full epithelial thickness without basement membrane
penetration, representing a preinvasive malignant lesion. Invasive carcinoma breaches the basement membrane;
hyperplasia and metaplasia are not malignant.
