HESI A2

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. The student _____ for the final exam.

A. was preparing
B. was studying
C. had studied
D. is studying

Correct answer: B

Rationale: In the given sentence, the past continuous tense 'was studying' is the most appropriate choice to indicate an ongoing action in the past. 'Was preparing' (choice A) implies a completed action rather than an ongoing one. 'Had studied' (choice C) is past perfect tense, which is not suitable for indicating an ongoing action. 'Is studying' (choice D) is present continuous tense and does not fit the past context of the sentence.

3. What does Manifestation mean?

A. A symptom or sign of a condition
B. An indication or sign of a condition
C. A treatment plan
D. A type of diagnosis

Correct answer: B

Rationale: Manifestation means an indication or sign of a condition. It is not a treatment plan (choice C) or a type of diagnosis (choice D). While choice A is close, 'symptom' is more specific than 'indication' in this context, making choice B the most accurate.

4. Identify the incomplete sentence.

A. While they were sleeping.
B. The dog slept.
C. The sun rises in the east.
D. They went home.

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.

5. If someone is disseminating information, what are they doing?

A. Withholding it
B. Broadcasting it
C. Destroying it
D. Complicating it

Correct answer: B

Rationale: When someone is disseminating information, they are spreading it widely or broadcasting it to reach a larger audience. Therefore, the correct answer is B: 'Broadcasting it.' This process involves sharing information to make it widely known and accessible. Choice A, 'Withholding it,' is incorrect as it means keeping information back rather than sharing it. Choice C, 'Destroying it,' is incorrect as it means to eliminate or get rid of the information, which is the opposite of disseminating. Choice D, 'Complicating it,' is incorrect as it means making something more complex or difficult to understand rather than spreading it.
