1. Which type of cellular adaptation is characterized by a decrease in
cell size and metabolic activity due to reduced workload or decreased
blood supply?
A. Hypertrophy
B. Hyperplasia
C. Atrophy — CORRECT ANSWER
D. Metaplasia
Rationale: Atrophy is a decrease in cell size and metabolic activity
resulting from reduced workload, denervation, diminished blood
,supply, inadequate nutrition, or aging. Hypertrophy is an increase in
cell size, hyperplasia is an increase in cell number, and metaplasia is
the replacement of one differentiated cell type with another.
2. A patient with chronic gastroesophageal reflux disease develops
replacement of normal stratified squamous esophageal epithelium
with columnar epithelium. This adaptive change is known as:
A. Dysplasia
B. Metaplasia — CORRECT ANSWER
C. Anaplasia
D. Hyperplasia
Rationale: Metaplasia is the reversible replacement of one
differentiated cell type with another in response to chronic irritation
or inflammation. Barrett's esophagus represents metaplastic change
from squamous to columnar epithelium in response to chronic acid
reflux.
,3. Which cellular change is considered a precursor to malignancy
and is characterized by abnormal variations in cell size, shape, and
nuclear appearance?
A. Metaplasia
B. Hypertrophy
C. Dysplasia — CORRECT ANSWER
D. Atrophy
Rationale: Dysplasia is characterized by abnormal cellular changes
including pleomorphism (variation in size and shape),
hyperchromatic nuclei, and increased mitotic activity. While
dysplasia is not cancer, it is considered a precursor lesion that may
progress to malignancy.
4. A patient has been exercising his arms repeatedly. Which
statement by the nurse explains the increase in the size of the arms?
A. "Your cells have atrophied in response to increased oxygen."
, B. "Your cells have hypertrophied in response to increased
workload." — CORRECT ANSWER
C. "You have increased your number of cells due to increased
oxygenation."
D. "You have caused the cells to clump together in response to
exercise."
Rationale: Hypertrophy refers to an increase in the size of individual
cells, which results in an increase in the size of the organ. This is
commonly seen in skeletal and cardiac muscle in response to
increased workload.
5. Which statement would a nurse tell a patient to best describe
apoptosis?
A. "Apoptosis describes increase in number of cells."
B. "Apoptosis occurs in irreversibly damaged cells."
C. "Apoptosis is an increase in the size of cells."
