HESI A2 Reading Comprehension 2024

Correct Answer: C

Rationale: The correct answer is C: The cessation of sweat is not necessarily a positive sign. After reading the passage, it mentions the importance of sweating as a mechanism to cool the body. If sweating stops, it indicates a potential issue with the body's ability to regulate temperature. This conclusion is supported by the passage's emphasis on the role of sweating in heat regulation. Choices A, B, and D can be ruled out because they do not align with the information provided in the passage. Choice A makes an assumption about increased deaths from heatstroke, which is not explicitly discussed. Choice B makes a generalization about heat exhaustion, which is not mentioned in the passage. Choice D makes a claim about dangerous temperatures, which is not relevant to the passage's focus on sweating and heat regulation.

Correct Answer: C

Rationale: The correct answer is C because the passage suggests that NASA will use the data gathered from the mentioned twin study for planning future trips. This can be inferred from the text mentioning the importance of understanding how spaceflight affects the human body and mind to prepare for long-duration missions like those to Mars. Choice A is incorrect as there is no mention of planning new twin studies specifically for Mars missions. Choice B is incorrect as the passage does not mention other agencies studying astronauts. Choice D is incorrect because the passage does not imply that NASA prioritizes physiology over psychology; it simply highlights the importance of studying both aspects for future missions.

Correct Answer: B

Rationale: The correct answer is B because the passage does not mention omega-3s reducing the risk of diabetes. The rationale is based on careful reading and understanding of the passage content. Reduced blood pressure, improved memory, and alleviated depression are benefits of omega-3s that are explicitly mentioned in the passage. The other choices are incorrect because they are not supported by the information provided in the passage. This demonstrates the importance of paying attention to specific details and avoiding assumptions when answering multiple-choice questions.

Correct Answer: D

Rationale: The correct answer is D: Drowsiness. Heat exhaustion signs include dizziness, nausea, and headache due to heat exposure. Drowsiness is not a typical symptom of heat exhaustion. People experiencing heat exhaustion are more likely to feel fatigued rather than drowsy. Heat exhaustion is characterized by an increase in body temperature, dehydration, and excessive sweating. Therefore, drowsiness is not a common sign associated with heat exhaustion.

Correct Answer: B

Rationale: The correct answer is B: Harmless. In the first paragraph, innocuous is used to describe something that is not harmful or offensive. The word implies that the subject is safe and poses no threat. The other choices are incorrect because: - A: Undiscovered does not relate to the meaning of innocuous. - C: Imperceptible means unable to be perceived, which is not the same as harmless. - D: Purposeless implies lacking a purpose, which is different from being harmless.
