Questions & Verified Answers
1. Which process involves the replacement of one mature cell type by another, often less differentiated,
cell type?
A. Metaplasia
B. Hypertrophy
C. Atrophy
D. Dysplasia
Answer: A
Rationale: Metaplasia is the reversible replacement of one mature cell type by another, frequently occurring in response to
chronic irritation.
2. A patient is diagnosed with myocardial infarction. What type of cell death is most likely occurring in
the affected heart tissue?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
Answer: A
Rationale: Coagulative necrosis primarily occurs in the heart, kidneys, and adrenal glands, typically resulting from hypoxia
due to severe ischemia.
3. Which electrolyte imbalance is most commonly associated with the development of peaked T waves
on an EKG?
A. Hyperkalemia
B. Hypernatremia
C. Hypokalemia
D. Hypocalcemia
Answer: A
Rationale: Hyperkalemia (high serum potassium) causes narrow and peaked T waves due to altered myocardial
repolarization.
4. In the Renin-Angiotensin-Aldosterone System (RAAS), what is the primary function of Angiotensin II?
A. Promote sodium excretion
B. Vasodilation
C. Systemic vasoconstriction
D. Decrease blood pressure
Answer: C
Rationale: Angiotensin II is a potent vasoconstrictor that increases systemic blood pressure and stimulates the release of
aldosterone.
