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. What is the meaning of NEBULOUS?

A. Clear
B. Vague
C. Precise
D. Obvious

Correct answer: B

Rationale: The correct answer is B, 'Vague.' Nebulous means something that is vague or unclear. Choice A, 'Clear,' is incorrect as it represents the opposite meaning of nebulous. Choice C, 'Precise,' is incorrect as it denotes clarity and exactness, which is the opposite of nebulous. Choice D, 'Obvious,' is also incorrect as it implies something that is easily understood or seen, unlike nebulous which refers to something unclear or hazy.

3. The healthcare provider asked about the patient's CONDITION.

A. A place in society
B. Ability to pay
C. Whereabouts
D. Physical state

Correct answer: D

Rationale: In a medical setting, when a healthcare provider asks about a patient's 'condition,' they are typically inquiring about the patient's physical state or health status. This encompasses aspects such as vital signs, symptoms, diagnosis, treatment progress, and overall well-being. 'A place in society,' 'Ability to pay,' and 'Whereabouts' are unrelated to the patient's health status and are not typically what a healthcare provider would ask about in this context. Therefore, the correct answer is 'Physical state,' as it aligns best with the context of healthcare and patient care.

4. What is the best meaning of Pernicious?

A. Harmless
B. Destructive
C. Helpful
D. Harmful

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

5. What does the word Querulous mean?

A. Shouting
B. Complaining
C. Crying
D. Praising

Correct answer: B

Rationale: The correct answer is B: 'Complaining.' Querulous is an adjective that describes someone who is constantly complaining or irritable. It is not related to shouting (Choice A) or crying (Choice C). Choice D, 'Praising,' is the opposite of the meaning of querulous and therefore incorrect.
