HESI A2 Vocabulary 2024

Correct Answer: C

Rationale: The correct answer is C: Scornful. Contemptuous and scornful are synonyms, both indicating a feeling of disdain or disrespect towards someone or something. Sympathetic (A) means showing compassion, exhausted (B) means very tired, and insensitive (D) means lacking empathy. These choices are incorrect as they do not convey the same meaning as contemptuous.

Correct Answer: B

Rationale: The correct answer is B: Improve. In the given sentence, 'ameliorate' is used in the context of making something better or reducing its negative effects, which aligns with the meaning of 'improve.' It means to alleviate or enhance a situation. Choices A, C, and D are incorrect because 'ameliorate' does not mean to cause, reveal, or restore in this context. The word 'ameliorate' specifically implies a positive change or enhancement, making 'improve' the most suitable choice.

Correct Answer: C

Rationale: The correct answer is C: Bruises. A contusion refers to a bruise caused by a blunt force trauma that damages the small blood vessels beneath the skin without breaking the skin itself. In the given sentence, the context of 'treated on-site' implies a minor injury that can be managed without the need for immediate medical attention. A: Breaks - This term typically refers to fractures or disruptions in the continuity of bones, not applicable in the context of the sentence. B: Disorientation - This term refers to a state of confusion or loss of direction, not related to physical injuries such as contusions. D: Abrasions - Abrasions are superficial wounds where the skin is scraped or rubbed off, different from contusions which involve internal bleeding beneath the skin.

Correct Answer: D

Rationale: The correct answer is D: Emotional behavior. Histrionics refers to overly dramatic or theatrical behavior, often exaggerated and insincere. This aligns with the definition of emotional behavior. Option A, accomplishments, is unrelated. Option B, daring acts, does not capture the emotional aspect of histrionics. Option C, examinations, is completely unrelated to the meaning of histrionics. Therefore, D is the most appropriate choice.

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.
