HESI A2 Practice Test Vocabulary

1. Which of the following is the plural form of the noun 'stimulus'?

A. Stimulus
B. Stimuli
C. Stimulis
D. Stimula

Correct answer: B

Rationale: The correct answer is 'Stimuli.' When forming the plural of 'stimulus,' the correct form is 'stimuli.' Choice A, 'Stimulus,' is the singular form, not the plural. Choice C, 'Stimulis,' is an incorrect spelling. Choice D, 'Stimula,' is also an incorrect form for the plural of 'stimulus.' Therefore, 'Stimuli' is the only correct plural form.

2. Finishing isn't as important as answering correctly.

A. Quick
B. As quick
C. So quickist
D. Quickly

Correct answer: D

Rationale: In this sentence, 'quickly' is the correct adverb form that should be used to modify the verb 'answering.' 'Quickly' is the adverb form needed here to describe how the action is performed. Choices A, B, and C are incorrect because they do not provide the appropriate adverb form required in the sentence.

3. Which word is a synonym for ASSURED?

A. Confirmed the truth of
B. Sympathized with
C. Denied the truth of
D. Made known to

Correct answer: A

Rationale: The correct answer is 'Confirmed the truth of' because 'assured' means to make certain or confident. To confirm the truth of something is to provide certainty, which aligns with the meaning of 'assured.' Choice B, 'Sympathized with,' is incorrect as it means to express compassion or understanding, which is not synonymous with 'assured.' Choice C, 'Denied the truth of,' is incorrect as it means to reject or contradict the truth, which is the opposite of 'assured.' Choice D, 'Made known to,' is incorrect as it refers to revealing or informing, which is not synonymous with 'assured.'

4. What does respite mean?

A. Rest
B. Relief
C. Pain
D. Burden

Correct answer: B

Rationale: Respite means a period of rest or relief. It refers to a temporary break or relief from something challenging or stressful. It is a time to relax and recharge, providing a sense of ease or comfort rather than pain or burden. 'Rest' (choice A) is related to respite but does not capture the aspect of temporary relief. 'Pain' (choice C) and 'Burden' (choice D) are opposite in meaning to respite, as they signify discomfort and heaviness, respectively, which are not synonymous with the concept of respite.

5. What does 'Parameter' mean?

A. A constant variable
B. A characteristic or constant factor
C. A measurable limit
D. A calculated risk

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.
