Vocabulary for HESI A2
1. The voice box may be called the ______
- A. Pharynx
- B. Larynx
- C. Trachea
- D. Esophagus
Correct answer: B
Rationale: The correct term for the voice box is the larynx. The pharynx is part of the throat involved in swallowing and breathing but not the voice production. The trachea is the windpipe responsible for air passage, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, in this context, the larynx is the most appropriate term.
2. Which phrase correctly completes the sentence? 'During the fight, I was hit on ___.'
- A. Head
- B. On head
- C. A head
- D. The head
Correct answer: A
Rationale: The correct answer is 'A: Head.' The phrase 'on the head' is a prepositional phrase indicating where the person was hit. 'Head' is the correct noun to complete the sentence. Choices B, C, and D are incorrect because they either add unnecessary articles ('a' or 'the') or incorrectly use the preposition 'on' before 'head.' The correct structure is 'hit on the head,' without any additional articles.

- A. Effectiveness
- B. Significance
- C. Corollary
- D. Conclusion
Correct answer: A
Rationale: In the context of the sentence provided, efficacy refers to the ability of counterfeit medicines to produce the intended or desired effect. Efficacy is closely related to effectiveness, which is the correct description in this context. 'Significance' (Choice B), 'Corollary' (Choice C), and 'Conclusion' (Choice D) do not accurately capture the meaning of efficacy in this context.

- A. The fast car drove over the bridge
- B. The car drove fast over the bridge
- C. The runner was fast
- D. He runs fast
Correct answer: D
Rationale: The sentence 'He runs fast' uses 'fast' correctly as an adverb. An adverb is used to describe a verb and in this case, 'fast' is describing how 'he runs.' Choices A, B, and C use 'fast' as an adjective, not an adverb. In choice A, 'fast' is describing the car, in choice B it is describing how the car drove, and in choice C it is describing the runner.
5. It's true that children depend on their parents for food, clothing, and ______.

Rationale: Children depend on their parents for providing basic needs like food, clothing, and shelter. 'Shelter' refers to the physical protection and housing that parents are responsible for providing to their children. While security, guidance, and affection are also important aspects of parenting, in the context of the question, the most essential need after food and clothing is shelter.
