Update
1. A patient with long-standing hypertension develops enlargement of the left ventricular
muscle. Which cellular adaptation is responsible?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Atrophy
Correct Answer: B. Hypertrophy
Rationale: Hypertrophy is an increase in cell size caused by increased workload. Cardiac muscle
cells respond to chronic pressure overload, such as hypertension, primarily through hypertrophy
rather than hyperplasia.
2. Which finding represents reversible cellular injury?
A. Cellular membrane rupture
B. Nuclear fragmentation
C. Fatty change
D. Extensive mitochondrial destruction
Correct Answer: C. Fatty change
Rationale: Fatty change can be reversible when the underlying injury is removed. Membrane
rupture, nuclear fragmentation, and severe mitochondrial damage are associated with
irreversible cellular injury.
3. Which type of necrosis is most commonly associated with myocardial infarction?
A. Liquefactive
B. Caseous
,C. Coagulative
D. Fat
Correct Answer: C. Coagulative
Rationale: Ischemic injury in most solid organs, including the heart, produces coagulative
necrosis. The basic tissue architecture remains recognizable for a period despite cell death.
4. Which type of necrosis is characteristic of a cerebral infarction?
A. Coagulative
B. Liquefactive
C. Caseous
D. Fibrinoid
Correct Answer: B. Liquefactive
Rationale: Brain tissue undergoes liquefactive necrosis following ischemic injury because
enzymatic digestion rapidly breaks down the damaged tissue.
5. Which type of necrosis is classically associated with tuberculosis?
A. Fat necrosis
B. Coagulative necrosis
C. Caseous necrosis
D. Liquefactive necrosis
Correct Answer: C. Caseous necrosis
Rationale: Tuberculosis commonly produces granulomatous inflammation with central caseous
necrosis, giving the affected tissue a characteristic cheese-like appearance.
6. Which process describes programmed cell death?
A. Necrosis
B. Apoptosis
C. Autolysis
D. Ischemia
Correct Answer: B. Apoptosis
,Rationale: Apoptosis is regulated, programmed cell death. Unlike necrosis, it generally occurs
without extensive surrounding inflammation.
7. A patient develops increased cell size in skeletal muscle after resistance training. Which
process is occurring?
A. Hypertrophy
B. Hyperplasia
C. Atrophy
D. Metaplasia
Correct Answer: A. Hypertrophy
Rationale: Skeletal muscle fibers enlarge in response to increased workload. This is hypertrophy,
meaning an increase in cell size.
8. Which cellular adaptation involves replacement of one mature cell type with another
mature cell type?
A. Dysplasia
B. Metaplasia
C. Hypertrophy
D. Hyperplasia
Correct Answer: B. Metaplasia
Rationale: Metaplasia is a reversible adaptive change in which one differentiated cell type is
replaced by another better able to tolerate a particular stress.
9. Which condition results from an increase in the number of cells?
A. Hypertrophy
B. Atrophy
C. Hyperplasia
D. Metaplasia
Correct Answer: C. Hyperplasia
Rationale: Hyperplasia means an increase in cell number. Hypertrophy, in contrast, refers to an
increase in cell size.
, 10. A patient experiences prolonged tissue hypoxia. Which metabolic change occurs first as
oxygen availability decreases?
A. Increased oxidative phosphorylation
B. Increased anaerobic glycolysis
C. Increased ATP production
D. Increased mitochondrial respiration
Correct Answer: B. Increased anaerobic glycolysis
Rationale: Reduced oxygen limits oxidative phosphorylation. Cells compensate by increasing
anaerobic glycolysis, which produces less ATP and increases lactate production.
11. Which laboratory finding is most consistent with metabolic acidosis?
A. Increased bicarbonate
B. Decreased bicarbonate
C. Increased pH
D. Decreased hydrogen ions
Correct Answer: B. Decreased bicarbonate
Rationale: Metabolic acidosis is characterized by a primary decrease in bicarbonate and a
decrease in blood pH. Causes include diarrhea, renal failure, and diabetic ketoacidosis.
12. A patient is hyperventilating because of severe anxiety. Which acid-base disturbance is
most likely?
A. Respiratory acidosis
B. Metabolic acidosis
C. Respiratory alkalosis
D. Metabolic alkalosis
Correct Answer: C. Respiratory alkalosis
Rationale: Hyperventilation causes excessive carbon dioxide elimination. The resulting decrease
in PaCO₂ produces respiratory alkalosis.
