HESI A2 Practice Vocabulary
1. What does 'Parameter' mean?
- A. A constant variable
- B. A characteristic or constant factor
- C. A measurable limit
- D. A calculated risk
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. Which sentence correctly uses a semicolon?
- A. I have a big test tomorrow; I can't go out tonight.
- B. She likes apples; oranges are her favorite.
- C. I went to the store; and I bought some milk.
- D. I like apples, but oranges are better.
Correct answer: B
Rationale: The sentence 'She likes apples; oranges are her favorite.' correctly uses a semicolon to connect two related independent clauses. The semicolon is used to separate two closely related ideas in a way that is stronger than a comma but not as final as a period. Choice A is incorrect because the conjunction 'but' is missing before 'I can't go out tonight.' Choice C is incorrect as the conjunction 'and' after the semicolon is unnecessary and disrupts the flow of the sentence. Choice D is incorrect because the semicolon is incorrectly placed before 'oranges are better,' where a comma or period would be more appropriate.
3. Concise is best defined as being ___________.
- A. exact
- B. brief
- C. accurate
- D. assembled
Correct answer: B
Rationale: Concise is best defined as being brief or to the point, expressing much in few words. While accuracy and exactness are important qualities, concise specifically refers to being brief or succinct in communication. Choice A ('exact') is not the best definition, as being precise in language does not necessarily mean being concise. Choice C ('accurate') is also not the best definition, as accuracy relates more to correctness than brevity. Choice D ('assembled') is unrelated to the definition of concise.
4. To censure something is to __________.
- A. inspect it
- B. denounce it
- C. admire it
- D. overlook it
Correct answer: B
Rationale: To censure something means to criticize or express strong disapproval of it. When something is censured, it is condemned or denounced for its actions or behavior. 'Inspect it' (Choice A) means to examine closely, 'admire it' (Choice C) means to regard with respect or warm approval, and 'overlook it' (Choice D) means to fail to notice or consider something. These choices do not align with the meaning of censure, making 'denounce it' (Choice B) the correct answer.
5. The _____ student was not well liked by his peers.
- A. Geniality
- B. Affably
- C. Gregarious
- D. Detestable
Correct answer: D
Rationale: The correct answer is 'Detestable.' In this context, 'detestable' means deserving intense dislike, which fits the sentence describing a student who is not well-liked. 'Geniality' (choice A) means warmth and friendliness, which is the opposite of what is described in the sentence. 'Affably' (choice B) means in a friendly and pleasant manner, which doesn't convey the idea of being disliked. 'Gregarious' (choice C) means sociable and outgoing, which is also not suitable for describing someone who is not well-liked.
