HESI A2 Vocabulary 2024

1. Choose the meaning of the word 'intramuscularly' in the following sentence: 'This vaccine must only be used intramuscularly and as a single-dose vial.'

Correct answer: B

Rationale: The word 'intramuscularly' in the sentence indicates that the vaccine should be used by injection directly into the muscles. This means the correct meaning is 'into muscles,' making option B the most suitable choice. Choices A, C, and D are incorrect because 'intramuscularly' specifically refers to administering something inside the muscle, not between muscles, without muscles, or on top of muscles.

2. What is the best description of the word 'insidious'?

Correct answer: A

Rationale: The correct answer is A: 'stealthy.' 'Insidious' is often used to describe something that proceeds in a gradual, subtle, but harmful way. It is not directly or openly harmful like 'deadly,' nor does it mean 'collapsed' or 'new.' Therefore, 'stealthy' best captures the meaning of 'insidious.'

3. Which word correctly completes the sentence? 'My sister gave the chocolate bar to my friend and ___.'

Correct answer: B

Rationale: The correct answer is 'Me.' In this sentence, 'me' is the correct object pronoun to use after the preposition 'to.' 'Myself' is a reflexive pronoun used when the subject and object of the sentence refer to the same person, which is not the case here. 'Us' is the object form of 'we,' which is incorrect in this context. Therefore, 'Me' is the most suitable choice.

4. What does the word 'pernicious,' commonly used to describe a harmful effect, mean?

Correct answer: B

Rationale: The correct answer is B: 'Destructive.' 'Pernicious' is used to describe something having a harmful effect, especially in a gradual or subtle way. The other choices are incorrect because 'Valued' means considered important or cherished, 'Finicky' means overly particular or fussy, and 'Perpetual' means continuing indefinitely or recurring.

5. What is the correct verb to complete the sentence? 'Economics ___ my least favorite subject at school.'

Correct answer: A

Rationale: The correct answer is A: 'Is.' In this sentence, 'Economics' is being treated as a singular subject, so the verb should also be singular. 'Is' is the correct singular form of the verb to agree with the singular subject 'Economics.' Choice B, 'Been,' is incorrect because it is the past participle form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice C, 'Am,' is incorrect because it is the first-person singular form of the verb 'be' and does not agree with the singular subject 'Economics.' Choice D, 'Are,' is incorrect because it is the plural form of the verb 'be' and does not agree with the singular subject 'Economics.'
