HESI A2 Reading Comprehension V1 2024

Correct Answer: B

Rationale: The correct answer is B because it accurately summarizes the passage by mentioning the role of the cardiovascular system in regulating blood pressure through baroreceptors, chemoreceptors, and the kidneys. The other choices are incorrect because they either focus on specific organs like the heart and kidneys (A), or only mention one aspect of blood pressure regulation (C and D). B provides a comprehensive summary that includes all key elements mentioned in the passage.

Correct Answer: C

Rationale: The correct answer is C: Something that is significant but unusual. In the context of the second paragraph, the word 'phenomenon' is used to describe something that is noteworthy and out of the ordinary. It implies that the subject being discussed is unique or remarkable. Choices A, B, and D are incorrect because they do not capture the essence of 'phenomenon' as being both significant and unusual. Option A focuses on being lifeless, B on nonchalant behavior, and D on chemical origin, none of which align with the meaning of 'phenomenon' in this specific paragraph.

Correct Answer: A

Rationale: The correct answer is A: free of bacteria. In the context of the second paragraph, the word 'sterile' is most likely referring to the cleanliness and lack of bacteria in the environment. This is supported by the fact that the paragraph is discussing medical equipment and the importance of maintaining sterility to prevent infection. Choice B, healthy, is incorrect as 'sterile' does not necessarily mean healthy. Choice C, delicious, is unrelated to the context and does not make sense. Choice D, impotent, is also unrelated and does not fit the context of the paragraph.

Correct Answer: D

Rationale: The correct answer is D because the author's primary purpose is to inform the reader about the stages of the water cycle. This can be inferred from the content of the essay, which likely discusses topics such as evaporation, condensation, precipitation, and collection. The other choices are incorrect because they do not align with the main focus of the essay. Choice A focuses on persuading readers to conserve water, which may be a related topic but not the main purpose of the essay. Choice B is about persuading readers against runoff, which is not the central theme. Choice C discusses analyzing different types of runoff, which is also not the primary purpose of the essay.

Correct Answer: A

Rationale: The correct answer is A: call into service. In the context of the second paragraph, 'enlist' means to join or sign up for a particular cause or service. This is evident from the sentence mentioning individuals joining the army. Choice B, write down, is incorrect because 'enlist' doesn't refer to simply writing something. Choice C, send away, is incorrect as it implies the opposite meaning of 'enlist.' Choice D, put across, is also incorrect as it does not capture the idea of joining or signing up as 'enlist' does.
