HESI A2 Practice Vocabulary

1. What does 'Parameter' mean?

Correct answer: B

Rationale: The correct answer is B: 'A characteristic or constant factor.' In the context of systems or experiments, a parameter is a fixed element that influences the behavior or outcome. It is not a variable like in choice A, which can change. Choice C, 'A measurable limit,' is incorrect as a parameter is not necessarily a physical limit but a defining factor. Choice D, 'A calculated risk,' is unrelated to the definition of a parameter.

2. Identify the incomplete sentence.

Correct answer: A

Rationale: The correct answer is A, 'While they were sleeping.' This is an incomplete sentence as it lacks a main clause. A complete sentence should have both a subject and a predicate to express a complete thought. In this case, the subordinating conjunction 'while' introduces a dependent clause that needs to be connected to an independent clause to form a complete sentence. Choices B, C, and D are complete sentences as they each contain a subject and a predicate, expressing a complete thought.

3. Another word for AFFECT is?

Correct answer: D

Rationale: Correct answer: Another word for AFFECT is INFLUENCE. Affect and influence are synonymous when used in the context of producing an effect on something or someone. Choice A, 'Reduce,' is incorrect as it means to make something smaller or lessen its quantity. Choice B, 'Contaminate,' is incorrect as it means to make something impure or harmful. Choice C, 'Eliminate,' is incorrect as it means to completely remove or get rid of something.

4. Which word is NOT USED CORRECTLY? It sure isn't going to rain during the next playoff.

Correct answer: A

Rationale: The correct answer is A. 'Ain't' is not grammatically correct in formal writing or speech; it should be 'isn't.' 'Ain't' is considered slang and is not appropriate for formal contexts. The other choices ('During,' 'Sure,' 'Playoff') are used correctly in the sentence.

5. Which phrase correctly completes the sentence? 'As we celebrated the start of the evening festivities, our glasses ___ and a toast was made by our host.'

Correct answer: C

Rationale: The correct answer is 'Were raised.' This phrase is the correct passive form, indicating the action of lifting the glasses during the toast. Choices A, B, and D are incorrect because 'were risen' is not grammatically correct, 'were rose' is not the appropriate verb form, and 'arose' does not convey the action of lifting the glasses as required in the sentence.
