NR 283 EXAM 1
Q1. A patient’s skeletal muscle cells enlarge due to chronic weight lifting over
months. What process is occurring here?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
✔ Answer: B – Hypertrophy
Explanation: Hypertrophy is the increase in cell size due to increased workload, commonly
seen in muscle cells under stress such as weight training.
Q2. Which cellular change best describes a reversible increase in the number of cells
within a tissue?
A. Atrophy
B. Hyperplasia
C. Necrosis
D. Apoptosis
✔ Answer: B – Hyperplasia
Explanation: Hyperplasia refers to an increased number of cells, often seen in hormonal
stimulation or compensatory tissue growth.
Q3. A patient experiences permanent cell injury leading to membrane rupture and
inflammation. What type of cell death is most likely occurring?
,A. Apoptosis
B. Necrosis
C. Autophagy
D. Mitosis
✔ Answer: B – Necrosis
Explanation: Necrosis is uncontrolled cell death that leads to inflammation and membrane
rupture.
Q4. Which term describes a normal mature cell type being replaced by another
mature cell type due to chronic irritation?
A. Dysplasia
B. Metaplasia
C. Hyperplasia
D. Anaplasia
✔ Answer: B – Metaplasia
Explanation: Metaplasia is a reversible adaptive change where one adult cell type is
replaced by another better suited to stress.
Q5. A decrease in cell size due to reduced workload or lack of nutrients is best
described as what process?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Dysplasia
✔ Answer: B – Atrophy
Explanation: Atrophy occurs when cells shrink due to decreased demand, aging, or
reduced blood supply.
Q6. Which condition is most likely to cause hypoxic cellular injury in tissues?
A. Increased oxygen supply
B. Reduced blood flow
C. Excess glucose intake
, D. Hormonal imbalance
✔ Answer: B – Reduced blood flow
Explanation: Hypoxia occurs when oxygen delivery is impaired, commonly due to poor
perfusion or ischemia.
Q7. During apoptosis, which structural feature is most characteristic of the process?
A. Inflammation of surrounding tissue
B. Random cell rupture
C. Controlled cell shrinkage and DNA fragmentation
D. Massive tissue swelling
✔ Answer: C
Explanation: Apoptosis is programmed cell death with orderly breakdown without
inflammation.
Q8. A patient has chronic irritation of bronchial tissue leading to transformation of
ciliated epithelium into squamous epithelium. What is this called?
A. Dysplasia
B. Metaplasia
C. Hyperplasia
D. Neoplasia
✔ Answer: B – Metaplasia
Explanation: Chronic irritation leads to adaptive replacement of one mature cell type with
another.
Q9. Which cellular process involves abnormal variation in cell size, shape, and
organization that may precede cancer?
A. Atrophy
B. Dysplasia
C. Hyperplasia
D. Metaplasia
✔ Answer: B – Dysplasia
Explanation: Dysplasia is disordered growth and is considered precancerous.
