HESI A2 Vocabulary Practice Test

Correct Answer: A

Rationale: The correct answer is A: of. The phrase "within 24 hours of administration" indicates a specific time frame after the administration of the tuberculin skin test. The preposition "of" in this context signifies the relationship between the time frame (24 hours) and the event (administration of the test). Using "before" (B), "after" (C), or "during" (D) would change the meaning of the sentence and imply a different timing relationship, which is not accurate in this context. Therefore, choice A is the correct preposition to use in this sentence.

Correct Answer: B

Rationale: The correct answer is B: Regretful. Contrite means feeling remorse or guilt for one's actions. It is important to differentiate between guilt and regret. Guilt implies responsibility for wrongdoing, while regret is feeling sorry for a past action. In this context, contrite aligns more closely with regretful as it signifies a sense of remorse without necessarily indicating guilt. Choices A, C, and D are incorrect as they do not capture the essence of contrite, which is about expressing sorrow and seeking forgiveness rather than feeling guilty, shameful, or pleased.

Correct Answer: B

Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated. Innovation (A) means introducing something new, effective (C) means successful in producing a desired or intended result, and advanced (D) means at a higher level of progress or development. In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.

Correct Answer: A

Rationale: Vacuous means lacking contents or empty. In this context, choice A (Empty) is the correct answer because vacuous specifically refers to something being devoid of substance or meaning. Choice B (Full) is incorrect as it is the opposite of vacuous. Choice C (Dense) is also incorrect as it means having parts that are close together, which is not related to vacuous. Choice D (Bright) is unrelated as it refers to something being well-lit or intelligent.

Correct Answer: A

Rationale: The correct answer is A: living well. This choice completes the list of important things in the person's life. Making money and traveling abroad are specific actions, while "living well" encompasses a broader concept that includes both financial stability and enjoyable experiences. It implies a balanced, fulfilling life beyond just material wealth or external adventures. Choice B, "to live well," is incorrect because it changes the structure of the sentence and does not fit the parallel structure of the list. Choice C, "to be happy," is incorrect as it introduces a new concept that is not explicitly mentioned in the previous items in the list. Choice D, "enjoying life," is incorrect because it is too similar in meaning to "traveling abroad," making it redundant in the list. It does not provide a distinct and essential element like "living well" does.
