Question 1
A 65-year-old male smoker presents with chronic cough and
shortness of breath. Lung biopsy shows enlarged airspaces
with destruction of alveolar walls. This represents which type of
cellular adaptation? A) Hyperplasia
B) Hypertrophy
,Page 2 of 242
C) Atrophy
D) Metaplasia
Correct Answer: C) Atrophy
Rationale: Atrophy involves shrinkage of cells/tissues due to
decreased workload or blood supply. In emphysema, alveolar
wall destruction represents pathological atrophy. Hyperplasia is
increased cell number, hypertrophy is increased cell size,
metaplasia is change from one cell type to another.
Question 2
Which of the following is characterized by increased cell
NUMBER in response to hormonal stimulation?
A) Cardiac myocyte enlargement in hypertension
B) Endometrial thickening during menstrual cycle
C) Cervical squamous metaplasia
D) Skeletal muscle wasting in denervation
,Page 3 of 242
Correct Answer: B) Endometrial thickening during menstrual
cycle
Rationale: Endometrial proliferation is estrogen-driven
hyperplasia (increased cell number). Cardiac myocytes undergo
hypertrophy (increased size), not hyperplasia. Metaplasia is cell
type change. Atrophy is cell shrinkage.
Question 3
A 50-year-old woman with a pituitary adenoma has enlarged
hands, feet, and jaw. This represents:
A) Physiologic hyperplasia
B) Compensatory hypertrophy
C) Pathologic hypertrophy
D) Pathologic hyperplasia
Correct Answer: C) Pathologic hypertrophy Rationale:
Acromegaly results from excess GH, causing pathologic
hypertrophy of bones and soft tissues. While hyperplasia may
, Page 4 of 242
occur in some tissues, the acromegalic features are primarily
hypertrophic. Pathologic indicates disease-driven rather than
adaptive.
Question 4
Barrett's esophagus, where squamous epithelium is replaced
by columnar epithelium, is an example of:
A) Dysplasia
B) Metaplasia
C) Hyperplasia
D) Anaplasia
Correct Answer: B) Metaplasia
Rationale: Metaplasia is reversible replacement of one
differentiated cell type with another. Barrett's esophagus results
from chronic GERD damaging squamous epithelium, replaced by
more protective columnar cells. Dysplasia shows disordered
growth, anaplasia is lack of differentiation.
