HESI A2 Practice Vocabulary

1. What does 'Contour' mean?

A. Flat area
B. Shape or outline of something
C. Volume of a structure
D. Height of a structure

Correct answer: B

Rationale: The term 'Contour' specifically refers to the shape or outline of something. In art and geography, contours are used to represent the outline or shape of an object or landform, making choice B the correct definition. Choice A, 'Flat area,' is incorrect as it does not capture the essence of contour which is about the shape or outline. Choice C, 'Volume of a structure,' is unrelated to the concept of contour. Choice D, 'Height of a structure,' is also incorrect as contour is more about the shape and not the height of an object.

2. What is another word for antidote?

A. Purity
B. Habitat
C. Remedy
D. Venom

Correct answer: C

Rationale: Corrected Question: What is another word for antidote? Rationale: An antidote is a substance that can counteract the effects of poison or disease. The term 'remedy' is often used synonymously with antidote to indicate a solution or cure for a particular problem or ailment. Choices A, B, and D are incorrect as they do not directly relate to the concept of antidote. 'Purity' refers to cleanliness or being free from contaminants, 'Habitat' is the natural environment where an organism lives, and 'Venom' is a poisonous substance typically injected by animals like snakes or insects.

3. The development of the disease was INSIDIOUS.

A. Momentous
B. Sudden
C. Innocuous
D. Gradual

Correct answer: D

Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.

4. What does 'Ingest' mean?

A. To chew
B. To swallow for digestion
C. To spit out
D. To vomit

Correct answer: B

Rationale: The correct answer is B: 'To swallow for digestion.' Ingest means to take food, drink, or another substance into the body by swallowing it. Choice A, 'To chew,' is incorrect as chewing is the act of breaking down food with the teeth. Choice C, 'To spit out,' is incorrect as it is the opposite of ingesting, involving expelling something from the mouth. Choice D, 'To vomit,' is also incorrect as vomiting is forcibly expelling the contents of the stomach through the mouth, which is the opposite of ingesting.

5. What does Consistency refer to?

A. Color of a fluid
B. Degree of viscosity, how thick or thin a fluid is
C. Taste of a fluid
D. Smell of a fluid

Correct answer: B

Rationale: Consistency refers to the degree of viscosity of a fluid, indicating how thick or thin it is. Viscosity is the resistance of a fluid to flow, and it determines its consistency. Choices A, color, C, taste, and D, smell, are not related to consistency. Color, taste, and smell are sensory attributes that do not define the physical property of consistency in fluids.
