Reading Comprehension HESI A2 Practice Test

1. Which statement would not be inferred by the reader in the passage about MRSA?

A. Hospitals may soon limit the spread of infection with a new textile.
B. MRSA begins by infecting the skin.
C. You are most likely to contract MRSA in a crowded location.
D. Used clothing stores may harbor MRSA.

Correct answer: D

Rationale: The correct answer is D: 'Used clothing stores may harbor MRSA.' This statement is not supported by the passage. The passage mentions the spread of MRSA in hospitals, gyms, locker rooms, swimming pools, and other settings with frequent human contact, but it does not mention used clothing stores as a common location for MRSA. Therefore, it is an unlikely inference. Choice A is supported by the passage as it discusses the development of a new textile to halt the spread of hospital-associated MRSA. Choice B is also supported as the passage mentions MRSA as a skin infection. Choice C is supported by the passage as it states that MRSA has become ubiquitous in settings with frequent human contact.

2. The passage mentions all of these uses for microscopy EXCEPT ___________.

A. Ear surgery
B. Amputations
C. Vasectomies
D. Reconstructions

Correct answer: C

Rationale: The correct answer is C. The passage discusses various uses of microscopy in surgery, including ear surgery, amputations, and reconstructions. However, vasectomies are not mentioned as an application of microscopy in the text. Therefore, vasectomies are the exception among the listed uses. Choices A, B, and D are supported by details in the extract, making them incorrect answers. The passage highlights the uses of microscopy in delicate ear operations, repairing blood vessels in partially amputated limbs, and improving breast reconstructions. While vasectomies are mentioned briefly in the extract, they are not connected to the application of microscopy in the context of surgeries.

3. What is the overall tone of the essay?

A. Apathetic
B. Fascinated
C. Discouraged
D. Hopeful

Correct answer: C

Rationale: The overall tone of the essay is discouraged, as it conveys concern over the United States’ lower ranking in life expectancy and highlights various health issues contributing to this situation. The language used suggests frustration and disappointment regarding the country's health statistics, supporting option C as the correct answer.

4. What is the meaning of the word 'elasticity' in the last paragraph?

A. Something that is able to resist and be flexible
B. Something that is like plastic
C. Something that is dynamic and electrifying
D. Something that is silly

Correct answer: A

Rationale: 'Elasticity' refers to the ability of the arterial walls to resist and be flexible, which affects blood pressure. In the provided extract, it is mentioned that an increase in blood pressure can occur if the arterial walls lose some of their elasticity with age or disease. This demonstrates that elasticity refers to the property of being able to resist and be flexible, supporting choice A as the correct answer. The other choices, B, C, and D, do not accurately reflect the concept of elasticity in the context of arterial walls and blood pressure.

5. Why does the author mention 'impact craters' in line 16?

A. To explain the corrosive effects of atmospheric weathering
B. To explain why the Moon has no plant life because of meteorites
C. To show the result of the Moon not having an atmosphere
D. To show the result of the Moon not having active tectonic or volcanic activity

Correct answer: C

Rationale: The mention of impact craters in the text is to highlight the consequence of the Moon lacking an atmosphere. The absence of an atmosphere on the Moon leaves it vulnerable to meteorite impacts, resulting in the multitude of impact craters on its surface. Choice A is incorrect because the mention of impact craters is not related to atmospheric weathering but rather to the lack of an atmosphere. Choice B is incorrect as it misinterprets the reason for the absence of plant life on the Moon. Choice D is incorrect as the text explicitly states that the Moon lacks tectonic or volcanic activity, which is not the focus of the mention of impact craters.
