HESI A2

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. Which word correctly completes the sentence? 'Most children must learn for ___ the importance of good manners.'

A. Themself
B. Theirself
C. Theirselves
D. Themselves

Correct answer: D

Rationale: 'Themselves' is the correct reflexive pronoun to use when referring to 'children' in the plural form. The other options, 'themself,' 'theirself,' and 'theirselves' are not grammatically correct as they do not match the plural subject 'children.'

3. What is Hydration?

A. The process of dehydrating
B. Maintenance of body fluid
C. Loss of water
D. Draining fluids

Correct answer: B

Rationale: Hydration refers to the maintenance of body fluids. Choice A is incorrect as it describes the opposite process, dehydration. Choice C is incorrect as it focuses on the result of inadequate hydration rather than the concept itself. Choice D is incorrect as it does not accurately define hydration but rather implies removing fluids.

4. The man's heart attack scared him badly and he decided to have a regular check-up.

A. severely
B. badly
C. intensely
D. profoundly

Correct answer: B

Rationale: In this context, 'badly' is the appropriate adverb to describe the intensity of the fear caused by the heart attack. 'Severely' and 'intensely' do not convey the same meaning in this sentence. 'Profoundly' refers more to depth or seriousness of an emotion, which doesn't fit the context of fear caused by a heart attack.

5. What does concave mean?

A. Rounded inward
B. Rounded outward
C. Straight
D. Flat

Correct answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.
