HESI A2 Vocabulary 2023

1. The breastbone may be called the ___________.

A. stelic
B. steres
C. sterol
D. sternum

Correct answer: D

Rationale: The breastbone is called the sternum. It is a flat bone located in the center of the chest that connects the ribs together and protects the heart and lungs. The term 'stelic' (choice A), 'steres' (choice B), and 'sterol' (choice C) are not correct terminologies for the breastbone.

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

A. Between muscles
B. Into muscles
C. Without muscles
D. On top of muscles

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.

3. Which sentence is grammatically correct?

A. Somebody left their jacket on the train
B. Somebody left his or her jacket on the train
C. His jacket was left on the train
D. His or her jacket was left on the train

Correct answer: B

Rationale: The sentence 'Somebody left his or her jacket on the train.' is grammatically correct and respects gender neutrality. 'Somebody' is singular, so the pronoun 'their' in choice A is incorrect. Choice C changes the subject from 'somebody' to 'his,' making it grammatically incorrect. Choice D is grammatically correct, but it is less concise and more awkward than choice B, which smoothly combines 'his' and 'her' for gender-neutral language.

4. Select the meaning of the underlined word in the following sentence. The children became bellicose after too much time in the moving car.

A. Beautiful
B. Selfless
C. Tolerant
D. Quarrelsome

Correct answer: D

Rationale: The word 'bellicose' means showing aggression or a willingness to fight. In the context of the sentence, it suggests that the children became argumentative or confrontational after spending too much time in the moving car. Therefore, the correct meaning is 'quarrelsome.' Choices A, B, and C are incorrect because 'bellicose' does not mean beautiful, selfless, or tolerant. It specifically refers to a combative or aggressive behavior, which aligns with 'quarrelsome.'

5. What is the meaning of pernicious?

A. Harmless
B. Destructive
C. Infectious
D. Helpful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious means causing great harm or damage. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Infectious,' refers to the ability of a disease to spread. Choice D, 'Helpful,' is also the opposite of pernicious and does not capture the negative connotation associated with the term.
