HESI A2 Reading Comprehension V1 2024

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.

Correct Answer: C

Rationale: The correct answer is C: To inform the reader how the cardiovascular system regulates blood pressure. The writer's primary purpose is to educate the reader about the mechanisms and processes involved in regulating blood pressure within the cardiovascular system. This is evident from the focus on explaining how the cardiovascular system works to maintain blood pressure levels. The other choices are incorrect because they focus on different aspects such as the dangers of high blood pressure (A), the relationship between high blood pressure and heart attacks (B), and persuading the reader about the importance of controlling blood pressure (D), which are not the main objectives of the essay.

Correct Answer: A

Rationale: The correct answer is A: To consist of. In the context of the first paragraph, 'composed' refers to the elements or parts making up something. The word implies that something is made up of different components. This is evident as the paragraph discusses how the team is composed of individuals with diverse skills and backgrounds. Explanation of why other choices are incorrect: B: To be uniquely discovered - This does not fit the context of the paragraph which is describing the makeup of a team. C: To be set apart - This does not align with the meaning of 'composed' in the context of being made up of different parts. D: To be surprised - This has no relevance to the meaning of 'composed' in the paragraph.

Correct Answer: D

Rationale: The correct answer is D: perfect. In the first paragraph, 'ideal' is used in the context of describing the best possible situation or outcome. This aligns with the definition of 'perfect,' which means without fault or flaw. The other choices are incorrect because 'thoughtful' means considerate or reflective, 'confined' means restricted or limited, and 'hostile' means unfriendly or aggressive, none of which capture the meaning of 'ideal' in this context.

Correct Answer: C

Rationale: The correct answer is C because the author's primary purpose is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. This is evident as the essay likely discusses the technical aspects of electrocardiography. Choice A is incorrect because there is no indication of persuasion in the essay. Choice B is incorrect as the focus is not on entertaining but on providing information. Choice D is incorrect as the essay is not about analyzing the differences between specific nodes in the heart.
