NURS 302 Pathophysiology Exam
1 Questions With Correct Answers|
Latest Update
**Q1: A woman's uterus returns to its normal size after childbirth. This is an example of:**
A) Hypertrophy
B) Hyperplasia
C) Atrophy
D) Metaplasia
**Correct Answer: C) Atrophy**
,**Rationale:** Atrophy is a decrease in cell size that occurs when the stimulus for growth is removed.
After childbirth, the uterus returns to its normal size through atrophy. This is a normal adaptive
response once the demand for increased size is no longer present .

**Q2: The increase in muscle mass seen in a bodybuilder who lifts weights daily is an example of:**
A) Atrophy
B) Hypertrophy
C) Hyperplasia
D) Dysplasia
**Correct Answer: B) Hypertrophy**
**Rationale:** Hypertrophy is an increase in cell size resulting in an increase in organ size without an
increase in cell number. Skeletal muscle enlargement from weight lifting represents hypertrophy of
individual muscle fibers in response to increased workload .

**Q3: Which cellular adaptation involves an increase in the number of cells, resulting in increased tissue
mass?**
A) Atrophy
B) Hypertrophy
C) Hyperplasia
, D) Metaplasia
**Correct Answer: C) Hyperplasia**
**Rationale:** Hyperplasia is an increase in the number of cells in an organ or tissue, resulting in
increased tissue mass. It can be physiologic (e.g., menstruation, liver regeneration) or pathologic (e.g.,
warts) .
---
**Q4: A patient with chronic GERD develops replacement of normal stratified squamous epithelium of
the esophagus with columnar epithelium. This is an example of:**
A) Dysplasia
B) Metaplasia
C) Hypertrophy
D) Neoplasia
**Correct Answer: B) Metaplasia**
**Rationale:** Metaplasia is a reversible change in which one adult cell type is replaced by another
adult cell type. This typically occurs in response to chronic irritation and inflammation. Barrett's
esophagus from chronic GERD is a classic example .

**Q5: Which adaptive mechanism is most strongly associated with malignancy?**
