HESI A2

Vocabulary HESI A2 Practice Test

1. What does 'Flushed' refer to?

A. Swollen
B. Reddened or ruddy appearance
C. Discolored
D. Pale

Correct answer: B

Rationale: The correct answer is B: 'Reddened or ruddy appearance.' When someone is flushed, it means they have a red or ruddy complexion, often due to embarrassment, anger, or a physical reaction. Choices A, C, and D are incorrect because 'flushed' specifically refers to a red or ruddy appearance, not swelling, discoloration, or paleness.

2. What does the word Quarantine mean?

A. Isolation
B. Confinement away from the general population
C. Treatment
D. Exposure

Correct answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

3. What does Labile mean?

A. Stable
B. Changing rapidly and often
C. Unchanging
D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

4. Which sentence correctly uses a semicolon?

A. I have a big test tomorrow; I can't go out tonight.
B. She likes apples; oranges are her favorite.
C. I went to the store; and I bought some milk.
D. I like apples, but oranges are better.

Correct answer: B

Rationale: The sentence 'She likes apples; oranges are her favorite.' correctly uses a semicolon to connect two related independent clauses. The semicolon is used to separate two closely related ideas in a way that is stronger than a comma but not as final as a period. Choice A is incorrect because the conjunction 'but' is missing before 'I can't go out tonight.' Choice C is incorrect as the conjunction 'and' after the semicolon is unnecessary and disrupts the flow of the sentence. Choice D is incorrect because the semicolon is incorrectly placed before 'oranges are better,' where a comma or period would be more appropriate.

5. What is another word for CONCAVE?

A. Sunburned
B. Convex
C. Puffed out
D. Sunken

Correct answer: D

Rationale: The correct answer is 'D: Sunken.' Concave refers to a surface or shape that curves inward, while 'sunken' is the closest synonym, also indicating something that is depressed or hollowed inward. Choice 'B: Convex' is incorrect as it is the opposite of concave, representing a shape that bulges outward. Choices 'A: Sunburned' and 'C: Puffed out' do not relate to the concept of concave shapes.
