QUESTION 1.
A nursing student reviews a passage describing how a public health intervention
reduced disease incidence over five years. Which statement from the passage would
provide the strongest evidence that the intervention was effective rather than the
decline occurring by chance?
A. The intervention coincided with increased public awareness.
B. Statistical analysis demonstrated a significant reduction compared with similar
communities without the intervention.
C. Several participants believed the intervention improved health.
D. The intervention received positive media attention.
🔴 Correct Answer: B. Statistical analysis demonstrated a significant reduction
compared with similar communities without the intervention.
,🔵 Explanation: Statistical comparison with a control population provides stronger
evidence for causation than opinions or coincidental timing. The other options may
suggest possible influence but do not adequately distinguish the intervention's effect
from other contributing factors.
QUESTION 2.
A medication dosage increases by 15% from 240 mg. What is the new dosage?
A. 264 mg
B. 276 mg
C. 288 mg
D. 300 mg
🔴 Correct Answer: B. 276 mg
🔵 Explanation: Fifteen percent of 240 mg is 36 mg. Adding 36 mg to the original
dosage yields 276 mg. The remaining options result from incorrect percentage
calculations.
QUESTION 3.
A patient experiences difficulty digesting fats following surgical removal of the
gallbladder. Which physiological explanation best accounts for this finding?
A. Reduced pancreatic enzyme production
B. Inability to synthesize bile salts
C. Loss of bile storage and regulated release into the small intestine
D. Complete cessation of lipid absorption
🔴 Correct Answer: C. Loss of bile storage and regulated release into the small
intestine
🔵 Explanation: The liver continues producing bile after gallbladder removal, but the
gallbladder no longer stores and concentrates it for release during meals. Pancreatic
,enzyme production remains intact, bile synthesis continues, and fat absorption is
reduced rather than completely eliminated.
QUESTION 4.
Which sentence is grammatically correct?
A. Neither the physician nor the nurses was available.
B. Neither the physician nor the nurses were available.
C. Neither the physician or the nurses were available.
D. Neither the physician nor the nurses is available.
🔴 Correct Answer: B. Neither the physician nor the nurses were available.
🔵 Explanation: With "neither...nor," the verb agrees with the noun closest to it.
Because "nurses" is plural, the correct verb is "were." The other choices contain
agreement or conjunction errors.
QUESTION 5.
A graph shows a hospital's emergency department visits steadily increasing while
inpatient admissions remain relatively stable. Which conclusion is best supported?
A. Emergency visits increased without a proportional increase in hospital admissions.
B. Every emergency visit resulted in hospital admission.
C. Admissions decreased because emergency visits increased.
D. Emergency care became less necessary.
🔴 Correct Answer: A. Emergency visits increased without a proportional increase
in hospital admissions.
🔵 Explanation: The graph directly supports that emergency visits rose while
admissions stayed relatively constant. The remaining conclusions either introduce
unsupported causation or contradict the available information.
, QUESTION 6.
Which organelle is primarily responsible for ATP production during aerobic
respiration?
A. Ribosome
B. Golgi apparatus
C. Mitochondrion
D. Lysosome
🔴 Correct Answer: C. Mitochondrion
🔵 Explanation: Mitochondria generate most cellular ATP through oxidative
phosphorylation. Ribosomes synthesize proteins, the Golgi apparatus modifies and
packages proteins, and lysosomes perform intracellular digestion.
QUESTION 7.
A solution has a pH of 3. Compared with a solution at pH 5, it contains
approximately:
A. 2 times more hydrogen ions.
B. 20 times more hydrogen ions.
C. 100 times more hydrogen ions.
D. 1,000 times more hydrogen ions.
🔴 Correct Answer: C. 100 times more hydrogen ions.
🔵 Explanation: Each pH unit represents a tenfold change in hydrogen ion
concentration. A difference of two pH units equals 10², or 100 times greater hydrogen
ion concentration. The other values underestimate or overestimate the logarithmic
scale.
QUESTION 8.
Which inference is most justified after reading two articles presenting conflicting
conclusions about vaccine effectiveness?
