A patient with chronic anemia is most likely to
exhibit which cellular adaptation in response
to decreased oxygen delivery?
A) Hyperplasia
B) Hypertrophy
C) Atrophy
D) Metaplasia
Correct Answer: B) Hypertrophy
,Rationale: Hypertrophy is an increase in cell
size in response to increased workload or
demand. Chronic anemia leads to decreased
oxygen delivery, causing cardiac myocytes to
hypertrophy to compensate for increased
workload .
Which type of cellular adaptation is
characterized by a decrease in cell size due to
decreased workload, denervation, or reduced
blood supply?
A) Hypertrophy
B) Hyperplasia
C) Atrophy
D) Metaplasia
Correct Answer: C) Atrophy
Rationale: Atrophy is a decrease in cell size
that can result from decreased workload
(disuse), loss of innervation (denervation),
diminished blood supply (ischemia),
inadequate nutrition, or aging .
,The mammary glands enlarge during
pregnancy primarily as a consequence of
which type of hormonal event?
A) Metaplasia
B) Atrophy
C) Hyperplasia
D) Dysplasia
Correct Answer: C) Hyperplasia
Rationale: Hormonal hyperplasia occurs when
cells proliferate in response to hormonal
stimulation, such as the enlargement of
mammary glands during pregnancy .
Reversible replacement of one mature cell type
by another, such as epithelial changes in
smokers, is called:
A) Hyperplasia
B) Hypertrophy
C) Metaplasia
D) Dysplasia
Correct Answer: C) Metaplasia
, Rationale: Metaplasia is the reversible
replacement of one differentiated cell type
with another mature cell type, often in
response to chronic irritation or inflammation .
A patient with a Pap smear showing abnormal
cells that are not clearly malignant but show
cellular atypia and increased mitotic activity is
best described as having:
A) Metaplasia
B) Hyperplasia
C) Dysplasia
D) Anaplasia
Correct Answer: C) Dysplasia
Rationale: Dysplasia is a loss of cellular
uniformity and architectural organization,
characterized by cellular atypia and increased
mitotic activity, and is considered a precursor
to malignancy .
