HESI A2 Reading Comprehension V1 2024

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

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.

2. What is the meaning of the word 'phenomenon' in the second paragraph?

Correct answer: C

Rationale: In the context of the second paragraph, 'phenomenon' refers to something significant and unusual, specifically describing the scientific phenomenon known as the Doppler Effect. This effect explains the change in frequency of sound waves when a source of sound and the observer are in relative motion. Choices A, B, and D are incorrect because they do not accurately reflect the meaning of 'phenomenon' in this context. 'Lifeless to the senses,' 'nonchalant,' and 'chemical in origin' do not align with the description of the Doppler Effect, which is a notable and uncommon scientific occurrence.

3. What is stated in this paragraph?

Correct answer: D

Rationale: The correct answer is D. The paragraph explains that harsh voice qualities usually result from too much tension in the throat and jaw. It further discusses how tension tightens muscles, leading to unpleasant voice tones. While the paragraph addresses the issue of harsh voices, it does not mention that only some men have harsh voices (choice A) or that relaxed people often exhibit this quality (choice B). Additionally, the paragraph does not touch upon whether everyone finds harsh voices irritating (choice C), only stating that not everyone may be bothered by it.

4. The word 'track' as used in the last paragraph of the passage can best be defined as ___________.

Correct answer: D

Rationale: In the context of the passage, 'track' refers to a 'paved, circular path' for running or walking. The last sentence of the passage encourages people to get off the couch and onto the track, indicating a physical path for exercise. Choice A, 'Keep a record of,' is incorrect as the context does not suggest any relation to recording information. Choice B, 'A new attitude,' is unrelated to the context of exercise and fatigue reduction. Choice C, 'Follow carefully,' does not fit the context of physical activity and energy levels discussed in the passage.

5. The author of the passage would probably agree with which of the following statements relating corrective lenses and aging eyes?

Correct answer: D

Rationale: The correct analogy for the role of corrective lenses in helping aging eyes can be compared to an athlete stretching before a game. Just as stretching prepares an athlete's body to perform optimally and avoid injury during a game, corrective lenses help aging eyes adjust and focus properly due to the hardening and loss of elasticity in the eye lens. Choices A, B, and C do not align with the concept of preparing or adjusting to address a specific issue, unlike the use of corrective lenses for aging eyes.
