Cellular Adaptation, Injury, and Death
1. A 45-year-old male presents with chronic hypertension. His cardiac muscle
cells have increased in size to accommodate the increased workload. This
cellular adaptation is best described as:
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale: Hypertrophy refers to an increase in cell size without an increase in cell
number. This occurs in tissues that cannot divide, such as cardiac muscle, in
response to increased workload (e.g., chronic hypertension). Hyperplasia (A)
involves an increase in cell number and occurs in tissues capable of mitotic
division. Metaplasia (C) is the reversible replacement of one mature cell type with
another. Dysplasia (D) refers to abnormal changes in cell size, shape, and
organization, often a precursor to malignancy.
DIF: Easy
KEY: Cellular adaptation
MSC: Physiologic process
NOT: Understanding cellular responses to stress
2. Which of the following is the most common cause of cellular injury?
A. Hypoxia
B. Physical trauma
C. Genetic mutations
D. Nutritional imbalances
Correct Answer: A
Rationale: Hypoxia (oxygen deprivation) is the most common and significant
cause of cellular injury and cell death. It leads to ATP depletion, failure of sodium-
, potassium pumps, cellular swelling, and ultimately necrosis. While physical trauma
(B), genetic mutations (C), and nutritional imbalances (D) can cause cellular injury,
hypoxia is the most prevalent mechanism across various disease states including
ischemia, anemia, and respiratory failure.
DIF: Easy
KEY: Cellular injury
MSC: Pathophysiology
NOT: Identifying primary mechanisms of cell damage
3. A biopsy specimen reveals cells with nuclear atypia, hyperchromatic, and
abnormal mitotic figures. These findings are most consistent with:
A. Atrophy
B. Hypertrophy
C. Dysplasia
D. Apoptosis
Correct Answer: C
Rationale: Dysplasia is characterized by abnormal cellular proliferation with cells
that have variable size and shape (pleomorphism), nuclear atypia, hyperchromatic
(dark-staining nuclei), and abnormal mitotic figures. It is often reversible if the
stimulus is removed but can progress to neoplasia. Atrophy (A) involves shrinkage
of cells. Hypertrophy (B) is increased cell size. Apoptosis (D) is programmed cell
death with characteristic morphologic changes including cell shrinkage and nuclear
fragmentation.
DIF: Moderate
KEY: Dysplasia
MSC: Cellular adaptation
NOT: Recognizing premalignant cellular changes
4. During which type of cell death does the cell membrane remain intact,
preventing inflammation?
