Question 1
What is the central claim of this passage?
A) Healthcare workers do not understand the importance of hand hygiene.
B) Hand hygiene is the most effective strategy for preventing HAIs, but compliance
remains a significant problem.
C) Alcohol-based hand rubs are superior to soap and water in all clinical situations.
D) The WHO has failed to reduce healthcare-associated infections.
Correct Answer: B
Rationale: The passage introduces HAIs, identifies hand hygiene as the top
prevention strategy, then spends the second paragraph on compliance failures.
Option A is not stated (awareness campaigns exist). Option C is contradicted by
the C. difficile exception. Option D is not in the passage .
Question 2
According to the passage, which group shows the lowest hand hygiene
compliance?
A) Nurses
B) Nursing assistants
C) Physicians
D) Housekeeping staff
Correct Answer: C
,Rationale: The passage states directly: "compliance is highest among nurses and
lowest among physicians." Options B and D are not mentioned .
Question 3
Based on the passage, in which situation is soap and water the recommended
method over alcohol-based rubs?
A) After any patient contact
B) When skin irritation is present
C) In cases involving Clostridioides difficile
D) When dispensers are inconveniently placed
Correct Answer: C
Rationale: Directly stated in the final sentence. Options A, B, and D are not
supported by the passage as reasons to prefer soap over rubs .
Question 4
Which of the following inferences is best supported by the passage?
A) Increasing the number of hand hygiene dispensers in clinical areas may improve
compliance rates.
B) Nurses have no barriers to hand hygiene compliance.
C) Soap and water should replace alcohol-based rubs in all clinical settings.
D) The WHO five-moment framework is ineffective.
Correct Answer: A
Rationale: The passage lists "inconvenient placement of dispensers" as a
compliance barrier. Removing that barrier (more dispensers) could improve
compliance—this is a direct inference. Option B is unsupported; the passage
implies barriers affect all workers. Options C and D contradict the passage .
Question 5
As used in the passage, the word "aseptic" most nearly means:
A) Requiring emotional care
B) Requiring surgical skill
,C) Free from contamination or infection-causing organisms
D) Related to patient documentation
Correct Answer: C
Rationale: In context, "clean or aseptic procedure" refers to procedures where
contamination must be prevented. The passage frames it alongside "before
performing"—which implies a sterile or clean-field requirement .

Question 6
What is 15% of 200?
A) 15
B) 30
C) 45
D) 60
Correct Answer: B
Rationale: To find the percentage, convert 15% to a decimal (0.15) and multiply it
by 200. 200 × 0.15 = 30 .
Question 7
A state trooper collected and recorded speeds of several cars. The speeds in miles
per hour are recorded below. Which of the following is the median of this data
set?
73, 81, 68, 75, 90, 78, 75, 82, 77, 71
A) 77
B) 22
C) 75
D) 76
, Correct Answer: D
Rationale: The median is the middle number when the data is ordered from least
to greatest. Ordered set: 68, 71, 73, 75, 75, 77, 78, 81, 82, 90. Since this set has 10
values, the median is the average of the 5th and 6th values: (75 + 77) ÷ 2 = 76 .
Question 8
Solve: 3/4 + 2/8 = ?
A) 1
B) 3/4
C) 1 1/4
D) 5/8
Correct Answer: A
Rationale: First, simplify 2/8 to 1/4. Then, 3/4 + 1/4 = 4/4, which simplifies to 1 .
Question 9
What is the decimal equivalent of 103%? (Use a leading zero if it applies. Do not
use a trailing zero.)
Correct Answer: 1.03
Rationale: To find the decimal equivalent of a percent, divide the number by 100
and remove the percent symbol. 103 ÷ 100 = 1.03 .
Question 10
If a patient's temperature is 101.3°F, what is the equivalent temperature in
Celsius?
A) 36.5°C
B) 37.5°C
C) 38.5°C
D) 39.5°C
Correct Answer: C
Rationale: Use the formula: °C = (°F - 32) × 5/9. (101.3 - 32) = 69.3; 69.3 × 5/9 =
38.5°C .
