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 does the quoted word 'adverse' mean in the following sentence? He complained of the 'adverse' side effects of his new medication.

A. Undesirable
B. Frequent
C. Noticeable
D. Constant

Correct answer: A

Rationale: The correct answer is A: 'Undesirable.' In this context, 'adverse' means harmful or undesirable, specifically referring to the negative side effects experienced from the medication. Choice B, 'Frequent,' is incorrect as 'adverse' does not imply how often the side effects occur but rather their nature. Choice C, 'Noticeable,' is incorrect as 'adverse' does not necessarily mean that the side effects are easily noticeable, but rather that they are harmful. Choice D, 'Constant,' is incorrect as 'adverse' does not indicate that the side effects are continuous but rather that they are negative.

Correct answer: D

Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.

4. Which term best describes a synthetic drug?

A. man-made

C. atypical

Choices B, C, and D are incorrect. 'Phony' means fake or fraudulent, not specifically related to synthetic drugs. 'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.

Choice A, 'To push forward,' is incorrect as 'depress' does not involve moving something forward. Choice C, 'To remove,' is incorrect as 'depress' does not entail taking something away. Choice D, 'To elevate,' is incorrect as it is the opposite of what 'depress' means.
