Vocabulary HESI A2 Practice Test

1. What is the meaning of NEBULOUS?

Correct answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.

2. The salesman recommended that he _____ his receipt for at least a month.

Correct answer: A

Rationale: The correct answer is 'keep.' In this context, the sentence is in the subjunctive mood, where the base form of the verb should be used after the word 'recommended.' Therefore, 'keep' is the appropriate verb choice. 'Keeps' (choice B) is incorrect as it does not align with the grammatical structure required in this sentence. Choices C and D are also incorrect as they do not match the verb form needed for the subjunctive mood.

3. What does 'Cease' mean?

Correct answer: B

Rationale: The correct answer is B: 'Come to an end.' Cease means to stop or come to an end. Choice A, 'Start,' is the opposite of what Cease means. Choice C, 'Pause,' implies a temporary stop, which is not the same as coming to an end. Choice D, 'Skip,' means to omit or bypass, which is different from the meaning of Cease.

4. What is the meaning of Regulations?

Correct answer: A

Rationale: Regulations refer to rules or directives established by authorities to govern conduct or actions. Therefore, the correct answer is A - 'Rules for Conduct.' Choice B, 'Official Standards,' is incorrect as regulations go beyond just setting standards to include specific rules for behavior. Choice C, 'Personal Guidelines,' is incorrect as regulations are not individualized but are generally applicable rules. Choice D, 'Suggestions,' is incorrect as regulations are mandatory and carry legal weight, unlike suggestions which are optional and not binding.

5. What does Elevate mean?

Correct answer: B

Rationale: The correct answer is B: 'To lift up or place in a higher position.' Elevate means to raise something to a higher level or position. Choice A, 'To lower,' is incorrect as it is the opposite of elevate. Choice C, 'To flatten,' is incorrect as it means to make something level or smooth, not to raise it. Choice D, 'To remove,' is also incorrect as it means to take something away, not to lift or raise it.
