SECTION 1: READING COMPREHENSION & ANALYSIS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 34-year-old nursing student is reading a passage about infection control protocols in a
hospital setting. The author states that hand hygiene compliance rates improved from
62% to 89% after implementing a visual reminder system. The author then concludes
that visual reminders are the most effective intervention for improving compliance.
What is the primary limitation of this author's conclusion?
A. The passage does not specify the brand of soap used in the hospital.
B. The improvement could be due to other simultaneous changes not mentioned. ✓
CORRECT
C. The percentage increase is mathematically impossible to achieve.
D. The nurses were likely already planning to improve before the study.
Correct Answer: B
Rationale: The author attributes the entire improvement to visual reminders without
ruling out confounding variables such as staff training, increased supervision, or
,seasonal factors that may have occurred simultaneously. Option A is incorrect because
the soap brand is irrelevant to the validity of the conclusion about visual reminders. In
clinical research, isolating variables is essential before drawing causal conclusions.
Question 2 of 50
A 28-year-old medical assistant is reviewing a patient education brochure about
diabetes management. The brochure contains the following sentence: "Patients should
monitor their blood glucose levels daily, eat a balanced diet, and regular exercise is
important." What error in sentence structure appears in this brochure?
A. The sentence contains a comma splice between two independent clauses.
B. The sentence shifts from imperative to declarative mood, creating faulty parallelism.
✓ CORRECT
C. The sentence uses passive voice inappropriately throughout.
D. The sentence lacks a subject in the final independent clause.
Correct Answer: B
Rationale: The sentence begins with two imperative verb phrases ("monitor," "eat") but
then shifts to a declarative clause ("regular exercise is important"), breaking parallel
structure. Option A is incorrect because there is no comma splice; the clauses are not
both independent in the same way. Parallel structure is critical in patient education
materials to ensure clarity and professionalism.
Question 3 of 50
A 45-year-old registered nurse is reading a research article about a new wound
dressing. The author presents data from a study conducted at a single urban trauma
center with 48 participants over six weeks. The author then recommends that all
emergency departments adopt this dressing as standard care. What is the most
significant weakness in the author's recommendation?
, A. The study duration was too short to assess long-term outcomes.
B. The sample size and setting limit generalizability to all emergency departments. ✓
CORRECT
C. The article did not include photographs of the wound dressings.
D. The participants were likely not representative of pediatric patients.
Correct Answer: B
Rationale: A single-center study with 48 participants lacks the external validity needed
to recommend universal adoption across diverse emergency department settings.
Option A identifies a real concern but is less fundamental than the generalizability
problem, since even a longer study at one site would still be limited. Evidence-based
practice requires careful evaluation of study external validity before applying findings
broadly.
Question 4 of 50
A 31-year-old pre-nursing student is analyzing a passage about healthcare reform. The
author writes: "While some argue that universal healthcare reduces costs, critics
counter that it limits patient choice. However, evidence from countries with single-payer
systems shows that administrative costs drop significantly, and patient satisfaction
remains high. Therefore, the United States should transition to a single-payer system
immediately." What type of logical fallacy does this argument contain?
A. The author commits an ad hominem attack against critics of universal healthcare.
B. The author makes a hasty generalization by applying international data to the U.S.
without addressing key differences. ✓ CORRECT
C. The author uses circular reasoning by restating the conclusion as a premise.
D. The author presents a false dilemma by suggesting only two healthcare options exist.
Correct Answer: B
Rationale: The author assumes that because single-payer works in other countries, it
will automatically work in the U.S. without considering structural, economic, or cultural
differences. Option D is tempting but incorrect because the author does not frame this
