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. Select the meaning of the word 'symmetric' in the sentence: 'The symmetric patterns of scarring were evident on the patient's back.'

A. scabbed
B. painful
C. corresponding
D. geometric

Correct answer: C

Rationale: In this context, 'symmetric' refers to patterns that correspond or are balanced on both sides, exhibiting symmetry. The scarring on the patient's back displayed a mirrored or corresponding arrangement. Choices A, B, and D are incorrect because 'symmetric' does not mean scabbed, painful, or geometric in this sentence.

3. Choose the meaning of the word 'predispose' in the following sentence: 'Being overweight may predispose a person to diabetes.'

A. Make susceptible
B. Bring to light
C. Save from harm
D. Pass over

Correct answer: A

Rationale: In this context, the word 'predispose' means to create a tendency or susceptibility towards a particular condition or outcome. It implies an increased likelihood or vulnerability. Options B, C, and D are incorrect because 'predispose' does not mean 'bring to light,' 'save from harm,' or 'pass over.' The correct choice is A as it accurately reflects the idea of making someone more susceptible to a specific condition or situation.

4. The doctor said he wanted to try other things before attempting an __________ procedure.

A. Internal
B. Painful
C. Experimental
D. Expensive

Correct answer: C

Rationale: The term 'invasive' refers to a procedure that involves entering the body, usually with a medical instrument or device. In the context provided, the doctor wants to try other non-invasive or less invasive options before resorting to an invasive procedure. 'Experimental' means untested or not yet proven to be effective, which aligns with the idea of exploring alternative methods before considering a more invasive approach. Choices A, B, and D are incorrect because they do not relate to the context of trying alternative procedures that are different from invasive ones.

5. PRECIPITOUS is best defined as being ______

A. Gradual
B. Swift
C. Slow
D. Delayed

Correct answer: B

Rationale: The correct answer is B: 'Swift.' PRECIPITOUS means something that is steep or sheer, often used to describe a very rapid or sudden change. This word does not relate to something gradual (choice A), slow (choice C), or delayed (choice D). Therefore, 'Swift' is the best definition for PRECIPITOUS.
