HESI A2 Reading Comprehension Practice Test

1. How does insomnia affect intellectual abilities?

A. Causes a deficit in memory, concentration, and attention.
B. Improves mental alertness.
C. Boosts concentration levels.
D. Has no effect on intellectual abilities.

Correct answer: A

Rationale: Insomnia affects intellectual abilities by causing a deficit in memory, concentration, and attention. The passage highlights that lack of sleep impacts memory, attention, and concentration, leading to feelings of irritation or depression. Therefore, choice A is correct. Choices B, C, and D are incorrect because they do not align with the negative impact insomnia has on intellectual abilities as described in the passage.

2. What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

A. Approved.
B. Sparse.
C. Requisite.
D. Aberrant.

Correct answer: C

Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

3. What does the term inhibitors mean, as used in the second paragraph?

A. Protectors
B. Deterrents

Rationale: Inhibitors refer to substances that slow down or prevent a particular process, in this case, the buildup of uric acid.

4. Which of the following is not listed as a detail in the passage about A Short History of the CDC?

A. Where the organization began.
B. Who first ran the organization.
C. When the organization changed its name.
D. What divisions make up the current CDC.

Correct answer: D

Rationale: The passage does not provide specific details about the divisions that currently make up the CDC. Instead, it focuses on the organization's historical context, original goals, and overall mission. Thus, D is correct as it identifies information not covered in the passage.

5. What is the meaning of the word 'emitting' as it is used in the second paragraph?

A. Repelling
B. Releasing
C. Closing
D. Charging

Correct answer: B

Rationale: In the context provided, 'emitting' means releasing, specifically referring to the electric currents being released in the body. The passage describes how electric currents are constantly being emitted in the body and can be detected on the body's surface, ultimately recorded by an electrocardiograph. This process is about the release of electric impulses, making 'releasing' the correct interpretation. Choice A, 'Repelling,' implies pushing away, which is not the intended meaning in this context. Choice C, 'Closing,' and Choice D, 'Charging,' do not align with the context of electric currents being emitted.
