Questions & Verified Answers
1. A patient with long-term cigarette smoking shows a change in the bronchial epithelium
from ciliated columnar cells to stratified squamous cells. What is this cellular adaptation
called?
A. Metaplasia
B. Hyperplasia
C. Dysplasia
D. Atrophy
Answer: A
Rationale: Metaplasia is the reversible replacement of one mature cell type by another mature cell
type, often as a response to chronic irritation. Understanding this helps the nurse notice early warning
signs and act before the problem gets worse. Early action often prevents bigger complications for the
client. This is important because the nurse must choose the action that keeps the client safest while
still meeting their basic needs. Always think about safety first when answering these questions.
2. Which electrolyte imbalance is most commonly associated with the development of
Torsades de Pointes?
A. Hypercalcemia
B. Hyperkalemia
C. Hyponatremia
D. Hypomagnesemia
Answer: D
Rationale: Hypomagnesemia is a well-known trigger for Torsades de Pointes, a specific type of
polymorphic ventricular tachycardia. This is important because the nurse must choose the action that
keeps the client safest while still meeting their basic needs. Always think about safety first when
answering these questions. Remembering this point will help you decide the best nursing action when
similar questions appear on the exam. Link the answer to the client’s current condition and risk level.

3. In the Renin-Angiotensin-Aldosterone System (RAAS), what is the primary function of
Angiotensin II?
A. Stimulating the release of insulin
B. Potent vasoconstriction and stimulation of aldosterone secretion
C. Promoting vasodilation and decreasing heart rate
D. Inhibition of ADH release
Answer: B
Rationale: Angiotensin II is a powerful vasoconstrictor that also stimulates the adrenal cortex to
release aldosterone, increasing blood pressure and volume. Clear understanding of this concept
improves both test performance and everyday clinical judgment. Practice applying it to short case
scenarios to lock the idea in place. Clear understanding of this concept improves both test

4. Which type of hypersensitivity reaction is mediated by IgE antibodies and involves the
release of histamine from mast cells?
A. Type III
B. Type II
C. Type I
D. Type IV
Answer: C
Rationale: Type I hypersensitivity (immediate) is IgE-mediated, leading to mast cell degranulation and
histamine release, common in allergies and anaphylaxis. In practice, this guides the nurse to set
priorities and protect the client from harm. Safety, nutrition, and clear communication are frequent
priorities. Clear understanding of this concept improves both test performance and everyday clinical
judgment. Practice applying it to short case scenarios to lock the idea in place.
