, 1. A nurse is reviewing a research article comparing two antihypertensive medications. The
study reports a statistically significant reduction in systolic blood pressure with
Medication A compared with Medication B but notes that the average reduction was only
2 mmHg. Which interpretation is most appropriate?
A. Medication A should always replace Medication B because the finding is statistically
significant.
B. The study proves Medication A is clinically superior in all patient populations.
C. The statistical significance should be interpreted alongside the clinical
significance before changing practice.
D. A statistically significant result means the difference is large enough to be clinically
meaningful.
Answer: C [Correct Answer]
Rationale: Statistical significance does not necessarily imply clinical significance. A 2 mmHg
difference may or may not justify a change in treatment depending on patient outcomes. A, B,
and D incorrectly equate statistical significance with universal or clinically meaningful benefit.
2. A patient reports dizziness after standing quickly. Which physiological mechanism most
directly helps restore blood pressure?
A. Increased insulin secretion
B. Activation of the baroreceptor reflex resulting in increased heart rate and
vasoconstriction
C. Decreased sympathetic nervous system activity
D. Increased filtration in the renal glomerulus
Answer: B [Correct Answer]
Rationale: Baroreceptors detect a drop in blood pressure and trigger sympathetic activation,
increasing heart rate and vascular resistance. A, C, and D do not provide the immediate
compensatory response.
3. A student solves a dosage calculation requiring conversion from milligrams to grams. If a
medication order is 750 mg, what is the equivalent amount?
A. 7.5 g
B. 75 g
C. 0.075 g
D. 0.75 g
Answer: D [Correct Answer]
Rationale: There are 1,000 mg in 1 g, so 750 mg equals 0.75 g. The remaining options reflect
incorrect decimal placement.
4. A passage argues that vaccination programs have reduced disease incidence while
acknowledging occasional adverse effects. Which statement best represents the author's
central claim?
A. Vaccines are completely free of risk.
B. Adverse effects outweigh public health benefits.
, C. Vaccination should be discontinued.
D. Vaccination provides substantial public health benefits despite the possibility of
uncommon adverse effects.
Answer: D [Correct Answer]
Rationale: The author's balanced argument emphasizes overall public health benefit while
recognizing limited risks. The other options distort the passage's position.
5. Which structure is primarily responsible for gas exchange in the lungs?
A. Bronchi
B. Trachea
C. Alveoli
D. Larynx
Answer: C [Correct Answer]
Rationale: Alveoli provide a large surface area for diffusion of oxygen and carbon dioxide. The
bronchi, trachea, and larynx primarily conduct air rather than exchange gases.
6. A solution has a pH of 2. Compared with a solution of pH 4, it is:
A. 100 times more acidic
B. 2 times more acidic
C. 10 times less acidic
D. 1,000 times more acidic
Answer: A [Correct Answer]
Rationale: Each pH unit represents a tenfold change in hydrogen ion concentration. A difference
of two pH units corresponds to a 100-fold difference.
7. During DNA replication, which enzyme synthesizes the new DNA strand?
A. Helicase
B. Ligase
C. Primase
D. DNA polymerase
Answer: D [Correct Answer]
Rationale: DNA polymerase adds nucleotides to the growing DNA strand. Helicase unwinds
DNA, primase lays RNA primers, and ligase joins DNA fragments.
8. A nurse reads that a patient's white blood cell count is significantly elevated. Which
explanation is most likely?
A. Reduced immune activity
B. Severe dehydration only
C. An immune response to infection or inflammation
D. Decreased bone marrow function
Answer: C [Correct Answer]
