HESI A2

Vocabulary HESI A2 Practice Test

1. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

2. To cauterize a wound is to ___________.

A. soothe it
B. cover it
C. stitch it
D. burn it

Correct answer: D

Rationale: To cauterize a wound is to use heat or a chemical to burn the wound in order to stop bleeding and prevent infection. This process helps seal off blood vessels and close the wound by burning the affected tissue. Choice A, 'soothe it,' is incorrect because cauterization involves burning the wound, which is a controlled way of treating it, not soothing it. Choice B, 'cover it,' is incorrect as cauterization involves a more aggressive approach than just covering the wound. Choice C, 'stitch it,' is incorrect as it refers to using sutures to close a wound, which is different from cauterization that involves burning the wound to seal it.

3. Select the sentence in which 'legal' is used as an adjective.

A. He is a legal resident of the United States
B. This is a legal action
C. That action was legal
D. He acted in a legal way

Correct answer: A

Rationale: The correct answer is A: 'He is a legal resident of the United States.' In this sentence, 'legal' is used to describe the type of resident he is, making it an adjective. The other choices use 'legal' as part of a noun phrase or an adverbial phrase, not as an adjective. Choice B uses 'legal' to describe the type of action, making it a noun adjunct. Choice C uses 'legal' to describe the legality of the action, making it part of an adjectival phrase. Choice D uses 'legal' to describe the manner in which he acted, making it an adverb.

4. The student observed the tricky procedure with a certain amount of trepidation. What does trepidation mean?

A. Confidence
B. Misgivings
C. Fear
D. Doubt

Correct answer: B

Rationale: The correct answer is B: Misgivings. Trepidation means a feeling of fear or apprehension. In this context, the student observed the procedure with a certain amount of trepidation, indicating that they were feeling uneasy or fearful. Choices A, C, and D are incorrect. Confidence (choice A) is the opposite of trepidation, as it denotes a feeling of self-assurance. Fear (choice C) is the closest synonym to trepidation, making it an attractive distractor, but it is not the correct answer. Doubt (choice D) is different from trepidation, as doubt refers to a feeling of uncertainty or lack of conviction, not necessarily fear or apprehension.

5. If someone is disseminating information, what are they doing?

A. Hiding it
B. Broadcasting it
C. Destroying it
D. Withholding it

Correct answer: B

Rationale: The correct answer is B: 'Broadcasting it.' Disseminating information means spreading or sharing it widely to reach a broader audience. Choice A, 'Hiding it,' is incorrect as disseminating involves making information known, not concealing it. Choice C, 'Destroying it,' is incorrect as disseminating means to distribute, not to eliminate. Choice D, 'Withholding it,' is incorrect because withholding information means keeping it back rather than sharing it openly.
