HESI A2 Reading Comprehension V1 2024

Correct Answer: B

Rationale: The correct answer is B: Releasing. In the context of the second paragraph, 'emitting' refers to giving off or releasing something, which aligns with the overall meaning of the paragraph. 'Repelling' (A) means to push away, 'Closing' (C) means to shut or block, and 'Charging' (D) means to energize with electricity - these choices do not fit the context of the paragraph. Therefore, B is the most suitable choice based on the definition and context of the word 'emitting.'

Correct Answer: A

Rationale: The correct answer is A because the passage does not mention changes in the ECG being used for diagnosing abnormal cardiac rhythm. Step 1: The passage describes the signal having a characteristic record called the electrocardiogram (B). Step 2: It mentions the 'wave of excitation' starting at the SA node (C). Step 3: It also discusses how the 'wave of excitation' spreads through the heart wall accompanied by electric changes (D). Therefore, A is the correct answer as it is not explicitly detailed in the passage.

Correct Answer: D

Rationale: The correct answer is D: for the general public. In the third paragraph, the word 'popular' is used to describe something that is liked, accepted, or enjoyed by a large number of people, which aligns with the definition of being 'for the general public.' Choice A, complicated, is incorrect because 'popular' does not imply complexity. Choice B, old-fashioned, is incorrect as 'popular' suggests current relevance. Choice C, beloved, is incorrect as 'popular' does not necessarily mean deeply loved but rather widely accepted.

Correct Answer: A

Rationale: The correct answer is A because baroreceptors and chemoreceptors are sensory receptors that detect changes in blood pressure and blood chemistry, respectively, and send nerve impulses to the brain to regulate these parameters. This is different from the kidneys, which are responsible for regulating blood volume by controlling the balance of salts, water, and waste removal through the production of urine. Therefore, the major difference lies in the function and location of these systems. Choices B, C, and D are incorrect because they either incorrectly describe the functions of baroreceptors, chemoreceptors, and kidneys or provide irrelevant information about their locations and interactions with other organs.

Correct Answer: A

Rationale: The correct answer is A: Something that is able to resist and be flexible. In the context of elasticity, it refers to the ability of a material to return to its original shape after being stretched or compressed. This aligns with the concept of resistance and flexibility. Choice B is incorrect as elasticity is not related to being like plastic. Choice C is incorrect as it does not capture the essence of elasticity being about resistance and flexibility. Choice D is incorrect as silliness has no relation to the concept of elasticity.
