HESI A2 Reading Comprehension V1 2024

Correct Answer: A

Rationale: The correct answer is A: requiring expert knowledge. In the fourth paragraph, the word 'technical' is used in the context of needing specific expertise or skill. The term 'technical' often refers to specialized knowledge or proficiency in a particular field. In this case, the text suggests that a certain level of expertise is necessary to understand or perform the task mentioned. Explanation for why the other choices are incorrect: B: Incomplete - This choice does not align with the context in the paragraph. The word 'technical' does not imply incompleteness, but rather a need for specialized knowledge. C: Foreign - The word 'technical' does not indicate something foreign or unfamiliar, but rather something requiring expertise. D: Plagiarized - This choice is unrelated to the meaning of 'technical' in the context. 'Plagiarized' refers to copying someone else's work without permission, which is not relevant to the paragraph's discussion of expertise.

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: 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.

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.
