HESI A2 Vocabulary 2023

1. Select the meaning of the word 'undulate' in the sentence: 'Each shiver made his muscles undulate beneath his skin.'

Correct answer: A

Rationale: In this context, 'undulate' means to move in a smooth, wave-like motion. An undulation of muscles is a subtle, continuous rippling or rolling movement, making 'ripple' the most appropriate synonym in this sentence. 'Shake' (Choice B) is incorrect as it implies a more abrupt and irregular movement. 'Flatten' (Choice C) and 'Unknot' (Choice D) are unrelated to the smooth, wave-like motion described in the sentence.

2. 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.

3. Which verb form best completes the sentence?

Correct answer: D

Rationale: The correct answer is 'Having.' In the sentence 'I am looking forward to having my birthday party next week,' 'having' is the correct present participle form of the verb 'have' to indicate an anticipated event. Choice A 'Going' is incorrect as it does not match the structure of the sentence. Choice B 'Go' is incorrect as it is the base form of the verb and does not fit grammatically. Choice C 'Have' is incorrect as it is the base form and does not convey the future action in the sentence.

4. Which word is NOT CORRECT? The student did not recognize which backpack was hers.

Correct answer: C

Rationale: The correct answer is 'C: Hers.' The possessive pronoun 'hers' does not require an apostrophe. The use of 'her's' with an apostrophe is grammatically incorrect. Choices A, B, and D ('Backpack,' 'Student,' and 'Recognize') are all spelled correctly and are grammatically sound in the sentence provided.

5. To vivify someone is to ___________.

Correct answer: B

Rationale: To vivify someone means to give life or animation to them. It involves revitalizing or energizing someone, rather than belittling, alarming, or spoiling them. Therefore, the correct answer is "animate him" as it is the most suitable synonym for vivify in this context. Choices A, C, and D are incorrect as they do not align with the meaning of vivify.
