HESI A2 Vocabulary 2024

Correct Answer: A

Rationale: The correct answer is A: A close group of friends. In the sentence provided, 'coterie' is used in the context of a social group that Julia is a part of, implying a close-knit circle of friends. This meaning aligns well with the context of being out at clubs together. The other choices are incorrect: B: An extended family does not fit the context of friends at clubs, C: An engaged person is unrelated to the context, and D: A manager or director is also irrelevant to the context of socializing at clubs.

Correct Answer: A

Rationale: The correct answer is A: Unfavorable. In the sentence, 'adverse' is used to describe a reaction caused by the medicine, indicating that it is not beneficial and has negative effects. 'Unfavorable' aligns with this meaning as it conveys something that is not conducive or adverse. The other choices are incorrect because B: Contrary means opposite, C: Noticeable means easily observed, and D: Startling means surprising, none of which capture the negative connotation of 'adverse' in this context.

Correct Answer: C

Rationale: The correct answer is C: assumed. "Hypothetical" means based on an assumption or guess, not proven. It is not synonymous with "rigorous" (A), which means thorough and precise. It is also not related to "short-term" (B), which refers to a brief duration. Furthermore, "convinced" (D) implies a state of belief or certainty, which is contrary to the tentative nature of something that is hypothetical. Thus, the most suitable definition for hypothetical is "assumed" as it reflects the uncertain and speculative nature of a hypothesis.

Correct Answer: B

Rationale: Step 1: Identify the cranial bone that fits the blank. Step 2: Recall that the bone forming the top and sides of the skull is the parietal bone. Step 3: Understanding that the parietal bone is a cranial bone reinforces choice B as the correct answer. Summary: Choice A is incorrect as the partial bone does not exist in the cranial structure. Choice C, pariah, is unrelated to cranial anatomy. Choice D, parhelion, is not a cranial bone but a term referring to a bright spot beside the sun.

Correct Answer: D

Rationale: The correct answer is D: Composed. Unruffled means calm and composed, so the word "composed" is a synonym for unruffled. "Concerned" means worried or anxious, opposite of unruffled. "Wholesome" means healthy or good, unrelated to unruffled. "Tedious" means boring or monotonous, also unrelated to unruffled. Therefore, the best choice is "Composed" as it aligns with the meaning of unruffled.
