HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Bitter. Acrid refers to a sharp and unpleasant taste or smell, often associated with bitterness. Bitter is the most synonymous term, as it conveys the same sharp and unpleasant quality. Smoky, nimble, and severe do not align with the definition of acrid, making them incorrect choices. Smoky refers to a smell associated with smoke, nimble relates to agility, and severe conveys seriousness or harshness, none of which capture the essence of acrid. Therefore, option A is the most appropriate synonym for acrid in this context.

Correct Answer: A

Rationale: The correct answer is A: Clumsy. 'Maladroit' means lacking skill or dexterity, often resulting in clumsiness. In the context of the sentence, it suggests that those who are maladroit (clumsy) should not become surgeons as surgery requires precision and skill. Explanation for other choices: B: Romantic - This choice is incorrect because 'maladroit' does not relate to being romantic. C: Untrained - This choice is incorrect as 'maladroit' is not specifically about lack of training, but about lack of skill or coordination. D: Self-conscious - This choice is incorrect as 'maladroit' does not imply being self-conscious, but rather lacking in skill or finesse.

Correct Answer: B

Rationale: The correct answer is B: Water that is lukewarm. Tepid bathwater refers to water that is neither too hot nor too cold, but rather at a moderate or lukewarm temperature. This is the ideal temperature for bathing as it is comfortable and soothing. Choice A is incorrect because tepid water is not salty. Choice C is incorrect because tepid water is not icy; it is warmer than cold water. Choice D is incorrect because tepid water refers to the temperature of the water, not the quantity.

Correct Answer: B

Rationale: The correct answer is B: Ulnar nerve. The "funny bone" is a term used to describe the ulnar nerve that runs along the inside of the elbow. When this nerve is bumped, it can cause a tingling or funny sensation. The ulnar nerve is not a bone, ruling out choices A and C. Choice D, biceps brachii, is a muscle in the arm and is not related to the "funny bone" sensation.

Correct Answer: A

Rationale: The correct answer is A: Bogus. 'Spurious' means not genuine or false, which aligns with 'bogus.' The sentence suggests the researcher made a misleading or false argument. Choice B, obscure, means unclear or hard to understand, which doesn't fit the context. Choice C, baffling, means confusing or perplexing, but doesn't capture the deceitful nature of 'spurious.' Choice D, outrageous, means shocking or offensive, which is not the same as being false or deceptive. Therefore, 'bogus' is the best fit for the context of the sentence.
