SECTION 1 – READING COMPREHENSION
Passage 1
In hospitals, infection-control protocols are continuously updated to reduce nosocomial
infections. One evidence-based practice gaining traction is the use of copper-infused bed linens.
Recent peer-reviewed studies demonstrate that copper ions disrupt bacterial cell membranes,
leading to a 36 % reduction in healthcare-associated infections when copper linens are used
compared to standard cotton. Despite higher acquisition costs, the overall cost–benefit analysis
favors copper linens because they shorten average length-of-stay by 0.7 days and lower
readmission rates. Administrators at Riverview Medical Center implemented the change in 2023;
within six months, the facility reported a 28 % drop in multidrug-resistant organisms on
high-touch surfaces and saved an estimated $1.2 million in unreimbursed care.
Question 1
What is the primary purpose of the passage?
A. To persuade readers that copper linens are aesthetically superior
B. To summarize evidence supporting copper-infused linens in infection control
C. To compare cotton and polyester fabric durability
D. To narrate the history of copper mining in medical supply chains
,Correct Answer: B
Rationale: The passage focuses on research findings, cost–benefit data, and a real-world case
study that collectively support copper linens as an infection-control measure.
A is incorrect because aesthetics are never discussed.
C is incorrect because durability is not compared.
D is incorrect because copper mining history is irrelevant to the text.
Question 2
Which statement from the passage best represents an opinion rather than a fact?
A. “copper ions disrupt bacterial cell membranes”
B. “the overall cost–benefit analysis favors copper linens”
C. “within six months, the facility reported a 28 % drop”
D. “they shorten average length-of-stay by 0.7 days”
Correct Answer: B
Rationale: The phrase “favors copper linens” is an interpretive conclusion based on data; the
other choices are measurable claims.
A is a factual mechanism reported in studies.
C is a documented outcome.
D is a quantified result.
Question 3
What can the reader most reasonably infer about Riverview Medical Center?
,A. It is a for-profit institution.
B. It had a higher-than-average infection rate prior to 2023.
C. It experienced financial savings after implementing copper linens.
D. It discontinued the use of cotton linens entirely.
Correct Answer: C
Rationale: The passage states the facility “saved an estimated $1.2 million,” implying financial
benefit.
A cannot be inferred because profit status is not mentioned.
B is unsupported; no baseline infection rate is given.
D is unsupported; total discontinuation is not stated.
Question 4
Which textual evidence best supports the claim that copper linens are cost-effective?
A. “copper ions disrupt bacterial cell membranes”
B. “shorten average length-of-stay by 0.7 days”
C. “gaining traction is the use of copper-infused bed linens”
D. “within six months, the facility reported a 28 % drop”
Correct Answer: B
Rationale: Reduced length-of-stay directly lowers hospital costs, supporting cost-effectiveness.
A explains antimicrobial action, not cost.
, C is a trend statement.
D shows infection reduction but not cost savings.
Question 5
If a skeptical administrator objects that copper linens are “too expensive,” which argument from
the passage would best counter the objection?
A. Copper linens feel softer to patients.
B. Copper linens lower readmission rates and reduce unreimbursed care.
C. Copper linens come in multiple colors.
D. Copper linens were used in ancient Egypt.
Correct Answer: B
Rationale: Lower readmissions and unreimbursed care directly address financial concerns.
A, C, and D are irrelevant to cost objections.
Passage 2
Sleep deprivation among nurses is linked to increased medical errors. A 2022 multi-site study
examined 1,200 twelve-hour shifts and found that nurses sleeping ≤ 5 hours between shifts had a
3-fold higher odds of making medication errors. Researchers implemented a “strategic nap”
protocol—allowing a paid 20-minute nap during shifts exceeding 10 hours—and errors dropped
18 %. Participants reported improved alertness on the Stanford Sleepiness Scale, and unit
turnover decreased 12 % over six months. Critics argue naps reduce bedside availability, yet
call-light response times remained unchanged because floating staff covered assignments.
