HESI A2 Vocabulary Practice Test

1. What does Nebulous mean?

Correct answer: B

Rationale: The correct answer is B: 'Vague.' Nebulous means something that is vague or unclear. Choices A, C, and D are incorrect because nebulous is the opposite of clear, distinct, and complex. Nebulous refers to something lacking definite form or limits, making it difficult to understand or perceive clearly.

2. In the address 'Mr. Ryan, 1600 Pennsylvania Ave., Washington, DC 20003,' which word is the salutation?

Correct answer: D

Rationale: The correct answer is 'D - Mr.' The salutation is the formal title used before a person's name, which in this case is 'Mr.' Other choices are incorrect as '1600 Pennsylvania Ave.' is the street address, '20003' is the zip code, and 'Ryan' is the recipient's name.

3. Which phrase is NOT used correctly in the sentence?

Correct answer: A

Rationale: The correct answer is A. "Do to" should be corrected to "due to" in this context. The sentence should read, "The client's hospital stay was prolonged, due to a superinfection." The phrase "due to" is the appropriate choice to indicate the cause of the prolonged hospital stay. Choices B, C, and D are all used correctly in the sentence and do not contain any errors.

4. Someone who is FRUSTRATED/ANNOYED is?

Correct answer: A

Rationale: The word 'exacerbated' means to make a problem, bad situation, or negative feeling worse. If someone is frustrated or annoyed, they are likely feeling worse due to a particular situation or circumstance. Choice B, 'transient,' means temporary or short-lived, which does not directly relate to the feeling of being frustrated or annoyed. Choice C, 'lithe,' means thin, supple, and graceful, which is not synonymous with being frustrated or annoyed. Choice D, 'terse,' means brief and to the point, which is unrelated to the context of feeling frustrated or annoyed.

5. Select the word that means 'an undesired problem that is the result of some other event.'

Correct answer: A

Rationale: The correct answer is 'Complication.' A complication refers to a secondary issue or difficulty that arises unexpectedly due to another event. It represents an undesired outcome. Choice 'B: Complement' is incorrect as it means something that enhances or completes, not an undesired problem. Choice 'C: Procedures' is incorrect as it refers to methods or steps, not an undesired problem. Choice 'D: Implemented' is incorrect as it means carried out, not an undesired problem.
