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 'carnivore'?

A. hungry
B. meat-eating
C. infected
D. demented

Correct answer: B

Rationale: The correct answer is B: 'meat-eating.' The term 'carnivore' specifically refers to an animal that primarily consumes meat. Choices A, C, and D are incorrect because 'hungry' means feeling the need to eat, 'infected' refers to being affected by a disease or pathogen, and 'demented' means to be mentally disturbed.

3. If they _____ that the weather was going to be so bad, they wouldn't have gone to the beach.

A. knew
B. had known
C. knew
D. could have known

Correct answer: B

Rationale: The correct answer is 'B: had known.' In this conditional sentence, the past perfect tense is required to indicate that knowing about the weather should have happened before going to the beach. 'Knew' (choice A and C) is in the simple past tense, which doesn't convey the sequence of events accurately. 'Could have known' (choice D) is incorrect as it implies a possibility of knowing in the past, but it doesn't fit the context of the sentence where the emphasis is on prior knowledge before going to the beach.

4. What is the meaning of Diameter?

A. The width of a structure
B. The distance across the center of an object
C. The height of an object
D. The radius of a circle

Correct answer: B

Rationale: The correct answer is B. Diameter is defined as the distance across the center of an object, typically a circle. Choice A is incorrect because width refers to the measurement of something from side to side, not necessarily through the center. Choice C is incorrect because height is a measurement from top to bottom, not across the center. Choice D is incorrect because the radius of a circle is the distance from the center to any point on the circle's circumference, not the distance across the center.

It is known to cause genital warts and various types of cancers, including cervical cancer. Choice A is incorrect because HPV is not related to a blood condition. Choice C is incorrect because HPV does not refer to heart rate. Choice D is incorrect as HPV is not a therapy but rather a virus.
