Vocabulary HESI A2 Practice Test

1. What does 'expand' mean?

A. To decrease in size
B. To increase in size or amount
C. To spread out
D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

2. Another word for ANTICIPATE is?

A. Predict
B. Evaluate
C. Compare
D. Forestall

Correct answer: A

Rationale: The correct answer is A: 'Predict.' Anticipate means to expect or foresee something happening in the future. 'Predict' is a synonym for anticipate as both involve forecasting or making an inference about a future event. 'Evaluate' means to assess or judge something, 'Compare' means to note similarities and differences, and 'Forestall' means to prevent or hinder something. These words do not have the same meaning as 'Anticipate.'

3. Choose the meaning of the word 'adverse' in the following sentence: 'Occasionally, this medicine causes an adverse reaction.'

A. Unfavorable
B. Contrary
C. Noticeable
D. Startling

Correct answer: A

Rationale: The word 'adverse' in the sentence is most closely aligned with the meaning of 'unfavorable.' An adverse reaction to a medicine signifies a negative or harmful response, which supports the definition of unfavorable. Choice B, 'Contrary,' does not accurately capture the negative connotation associated with 'adverse.' Choice C, 'Noticeable,' does not reflect the meaning in the context provided. Choice D, 'Startling,' suggests a more sudden or surprising nature, which is not the primary meaning of 'adverse' in this context.

4. Choose the meaning of the word vent in the following sentence: 'A tube is used to vent the gases to the outside.'

A. Block
B. Trade
C. Emit
D. Inhale

Correct answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off. 'Trade' is incorrect as it refers to the exchange of goods or services. 'Inhale' is incorrect as it means to breathe in, which is the opposite of venting gases out.

5. What is the best description for the word 'distal'?

A. Receives blood from lungs
B. Farthest from injury
C. Closest to heart
D. Empathetic

Correct answer: B

Rationale: The correct answer is B: 'Farthest from injury.' In medical terminology, 'distal' refers to the body part that is farthest from the point of reference or injury. The term is commonly used to describe the location of structures in relation to a point of origin or attachment. Choices A, C, and D are incorrect because 'distal' specifically denotes a spatial relationship in terms of distance from a point of reference, not blood flow, proximity to the heart, or emotional empathy.
