HESI A2 Vocabulary Practice Test

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Rationale: The correct answer is B: Outdated. Obsolete means no longer in use or relevant due to being outdated.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 In this context, the term 'obsolete' specifically refers to something that is no longer current or useful, making choice B the most appropriate answer.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: B

Rationale: The correct answer is B: Confinement away from the general population. Quarantine refers to the isolation of individuals who may have been exposed to a contagious disease to prevent the spread to others. This choice is correct because quarantine involves separating potentially infected individuals from the rest of the population. Choice A (Isolation) is similar but not specific to disease control measures. Choice C (Treatment) does not capture the concept of separation. Choice D (Exposure) is incorrect as quarantine is about preventing exposure, not promoting it.

Correct Answer: B

Rationale: The correct answer is B: Able to be heard. Audible refers to something that can be heard. This is because the term "audible" is derived from the Latin word "audire," which means "to hear." Therefore, when something is audible, it means it can be perceived by the sense of hearing. Incorrect choices: A: Impossible to hear - This is incorrect as audible means the opposite, something that can be heard. C: Visible - This is incorrect as audible pertains to sound, not sight. D: Silent - This is incorrect as audible refers to something that can be heard, not something that is silent.

Correct Answer: B

Rationale: The correct answer is B: Significantly important and dangerous. "Ominous" means giving the impression that something bad or unpleasant is going to happen. The word carries a sense of foreboding or threat. Choice A, "insignificant," is incorrect because ominous implies significance. Choice C, "trivial," is incorrect as it suggests unimportance, which is opposite to the meaning of ominous. Choice D, "harmless," is incorrect because ominous implies a potential for harm or danger. Therefore, the correct answer is B as it best captures the meaning of ominous in the context of something being important and dangerous.

Correct Answer: A

Rationale: The correct answer is A because "the thief" indicates a singular person, so the pronoun "he" should be used. The subject-verb agreement is crucial in this sentence. Choice B uses "he" correctly but includes a different verb. Choices C and D use the incorrect pronoun "they," which does not agree with "the thief." Additionally, "hid" in choice C is not the appropriate action after robbing a bank, and "fled" in choice D is plural and doesn't match with "the thief." Therefore, option A is the correct choice based on subject-verb agreement and logical consistency.
