HESI A2

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. A blood vessel that is distended is ___________.

A. overturned
B. swollen
C. twisted
D. overlong

Correct answer: B

Rationale: A blood vessel that is distended is swollen. Distention refers to the state of being stretched beyond normal limits, which can cause the blood vessel to expand and swell. The term 'distended' is often used to describe blood vessels that are enlarged or swollen due to various reasons such as increased blood pressure or blockages. Choice A, 'overturned,' does not relate to the enlargement or swelling of a blood vessel. Choice C, 'twisted,' describes a different condition where the blood vessel is coiled or rotated, not necessarily enlarged. Choice D, 'overlong,' does not accurately describe the state of a distended blood vessel; instead, it implies excessive length rather than enlargement.

3. The meteorologist had forecast rain, ____________ Sheila brought her umbrella to work.

A. Nor
B. Yet
C. Because
D. So

Correct answer: C

Rationale: The sentence implies a cause-and-effect relationship, so 'because' is the appropriate conjunction. 'Nor' is used in negative constructions, 'Yet' indicates contrast, and 'So' is used to show a consequence, none of which fit the context of the sentence.

4. Choose the meaning of the word 'coterie' in the following sentence: 'Julia and her coterie are often out at local clubs until the wee hours.'

A. A close group of friends
B. An extended family
C. An engaged person
D. A manager or director

Correct answer: A

Rationale: In this context, the word 'coterie' refers to a small group of people who share similar interests or activities, typically a close-knit circle of friends. The other choices are incorrect. 'An extended family' refers to relatives beyond the nuclear family, 'an engaged person' is someone committed to be married, and 'a manager or director' are job roles unrelated to the context of the sentence.

5. Ventral refers to which part of the body?

A. Top
B. Bottom
C. Front
D. Back

Correct answer: C

Rationale: Ventral refers to the front part of the body or an organ. It is the opposite of dorsal, which refers to the back part. So, when describing the direction or location of an anatomical structure, ventral would mean towards the front. Therefore, the correct answer is 'Front.' Choices A, B, and D are incorrect because 'Top' refers to superior, 'Bottom' refers to inferior, and 'Back' refers to dorsal, not ventral.
