HESI A2 Practice Vocabulary
1. What is the best description of aseptic?
- A. Infected
- B. Purified
- C. Contaminated
- D. Sterilized
Correct answer: B
Rationale: The correct answer is B: 'Purified.' Aseptic means free from contamination or purified. In medical and scientific contexts, aseptic techniques are used to prevent contamination and maintain sterility in environments or procedures. Choice A, 'Infected,' is incorrect as aseptic refers to being free from contamination, not being infected. Choice C, 'Contaminated,' is incorrect as aseptic means the opposite of contaminated. Choice D, 'Sterilized,' is incorrect as aseptic focuses on the absence of contamination rather than the process of sterilization.
2. What is the CORRECT CONTRACTION for 'will not'?
- A. Won't
- B. Willn't
- C. Wouldn't
- D. Will'nt
Correct answer: A
Rationale: The correct contraction for 'will not' is 'won't'. 'Willn't' (Choice B) is not a standard contraction in English. 'Wouldn't' (Choice C) is the contraction for 'would not,' not 'will not.' 'Will'nt' (Choice D) is not a recognized contraction in English. Therefore, 'won't' is the correct choice as the contraction for 'will not.'
3. Precipitous is best defined as being ____?
- A. Slow
- B. Swift
- C. Gradual
- D. Delayed
Correct answer: B
Rationale: The correct answer is B: 'Swift.' Precipitous is used to describe something that is steep, sheer, or done suddenly and without careful consideration. For example, a precipitous drop in the stock market. 'Slow' (Choice A), 'Gradual' (Choice C), and 'Delayed' (Choice D) do not align with the meaning of precipitous and are therefore incorrect.
4. 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.
5. Which word is NOT used correctly in the sentence? 'A sentence must always begin with a capital letter, but many people forget this rule.'
- A. Must always
- B. Simple
- C. Forget
- D. Capitol
Correct answer: D
Rationale: The correct answer is 'D: Capitol.' In this context, 'Capitol' is incorrect as it refers to a building where a legislative body meets. The correct term for uppercase letters is 'capital.' Choice A, 'must always,' is used correctly to emphasize the necessity of starting a sentence with a capital letter. Choice B, 'simple,' is not the incorrect word in the sentence. Choice C, 'forget,' is also used appropriately in the sentence to indicate the action of neglecting the rule.
