HESI A2 Vocabulary 2024

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: 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.

Correct Answer: A

Rationale: The correct answer is A: Unoriginal. In this context, "derivative" means lacking originality or being based on something else. The sentence suggests that the professor's lecture was not fresh or innovative. Choice B, monotonous, refers to lacking in variation or being dull, which is not directly implied by the sentence. Choice C, condescending, means showing a superior attitude, which is not indicated in the sentence. Choice D, long-winded, means overly verbose or wordy, which is not the main focus of the sentence. Thus, A is the best fit based on the context provided.

Correct Answer: A

Rationale: The correct answer is A: man-made. Synthetic drugs are artificially created in laboratories, making them man-made. Phony (B) means fake or counterfeit, which does not specifically describe synthetic drugs. Atypical (C) means unusual or not typical, which does not define synthetic drugs accurately. Futile (D) means pointless or ineffective, which is not related to the nature of synthetic drugs. In summary, the term "man-made" best describes synthetic drugs because they are produced through chemical synthesis in a controlled environment.
