HESI A2 Vocabulary 2023

Correct Answer: C

Rationale: The correct answer is C: To dispute the truth of. Impugn means to challenge the validity or truthfulness of something. This is the correct answer because impugning involves questioning or casting doubt on the credibility of a statement or claim. A: To instill with - This choice is incorrect because instill means to introduce gradually, which is not related to the meaning of impugn. B: To instruct about - This choice is incorrect because instruct means to teach or provide information, not to challenge the truth of something. D: To lament or complain about - This choice is incorrect because lamenting or complaining is about expressing sorrow or dissatisfaction, not about disputing the truth of something.

Correct Answer: D

Rationale: The correct answer is D: Fragile. In the sentence, 'tenuous' is used to describe the hold on reality as weak or delicate. The word 'fragile' best captures this meaning, as it implies something easily broken or damaged. Judicious (A) means showing good judgment, which is not relevant here. Deleted (B) means removed, which doesn't fit the context. Frantic (C) means wild or frenzied, which is not the intended meaning in this sentence. The key is to understand the context and choose the word that best conveys the intended meaning, which in this case is 'fragile.'

Correct Answer: B

Rationale: The correct answer is B: Dormant. Latent and dormant both refer to something existing but not actively expressed or visible. Flagrant means conspicuously offensive, making it the opposite of latent. Deceased means no longer alive, unrelated to latent. Postponed means delayed or rescheduled, not synonymous with latent. Therefore, the best synonym for latent among the choices provided is dormant.

Correct Answer: A

Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B: Radius. In the forearm, the radius is shorter than the ulna. The radius is located on the same side as the thumb, while the ulna is on the side of the pinky finger. The humerus is the upper arm bone, the scapula is the shoulder blade, and the fibula is a bone in the lower leg. So, the radius is the only bone among the choices that is actually located in the forearm and is shorter than its counterpart, the ulna.
