Vocabulary for HESI A2

1. What do contours refer to?

A. Color
B. Shape
C. Size
D. Texture

Correct answer: B

Rationale: Contours refer to the shape or outline of something. They represent the boundaries or curves that define the outer edges of an object or form. Colors, sizes, and textures do not encompass the concept of contours, making them incorrect choices in this context.

2. What is the meaning of the word 'hygiene' in the sentence: 'It is not wise to skimp on personal hygiene'?

A. Measures contributing to cleanliness
B. Financial resources
C. Insurance
D. Friendliness

Correct answer: A

Rationale: The correct answer is A: 'Measures contributing to cleanliness.' In the given sentence, 'hygiene' refers to practices that promote cleanliness and health, such as washing hands, taking showers, and maintaining a clean environment. Choice B, 'Financial resources,' is incorrect as hygiene does not pertain to money matters. Choice C, 'Insurance,' is unrelated to the concept of hygiene. Choice D, 'Friendliness,' is also incorrect as it does not align with the context of personal cleanliness and health.

3. Which word in the sentence needs to be corrected for proper grammar?

A. About it
B. A
C. With
D. Made

Correct answer: B

Rationale: The word 'A' should be corrected to 'an' in the sentence. The sentence should read, 'The nurse made an error with the medication, so the doctor made notes about it in the patient's file.' The article 'an' is used before a noun beginning with a vowel sound, like 'error' in this case. Choices A, C, and D are grammatically correct in the sentence and do not need to be altered.

4. What must a homeowner do to a section of a fence that is falling apart?

A. Buttress
B. Degrade
C. Hinder
D. Flounder

Correct answer: A

Rationale: To buttress a fence means to reinforce or support it, typically by adding extra material or structures to prevent it from falling apart. In this scenario, the homeowner needs to strengthen the deteriorating section of the fence, making 'buttress' the correct answer. 'Degrade' means to diminish in quality, which is the opposite of what the homeowner should do. 'Hinder' means to create obstacles or difficulties, not a solution for the falling fence. 'Flounder' means to struggle or fail, which is not related to repairing the fence.

5. 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.
