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. He had already finished studying at a(n) _____ when he was called to join the army.

A. university
B. academy
C. college
D. institute

Correct answer: A

Rationale: In the context provided, the correct answer is 'university.' The term 'university' is used to refer to higher education institutions that offer undergraduate and postgraduate degrees. While 'academy,' 'college,' and 'institute' are also types of educational institutions, 'university' is the most fitting choice here as it best aligns with the idea of completing higher education before joining the army.

3. Which term refers to the surgical removal of an organ's contents?

A. Excretion
B. Evisceration
C. Incision
D. Reduction

Correct answer: B

Rationale: The correct answer is B, 'Evisceration.' Evisceration specifically means the surgical removal of an organ's contents. Choice A, 'Excretion,' is the process of eliminating waste products from the body and is not related to surgical procedures. Choice C, 'Incision,' refers to the act of cutting into the body, commonly done in surgeries but not specifically related to removing organ contents. Choice D, 'Reduction,' generally means to make something smaller or lessen its size, which is not the term used for the surgical removal of an organ's contents.

4. Which sentence uses the VERB correctly?

A. I saw you standing in line at the Tilt-A-Whirl at the country fair.
B. I sang the national anthem before the country fair moto-cross race.
C. I ran toward the country fair arena with Nibbles the Rabbit.
D. I wore a white shirt and dark jeans to show my goat at the country fair.

Correct answer: D

Rationale: The correct answer is D: 'I wore a white shirt and dark jeans to show my goat at the country fair.' 'Wore' is the correct past tense form of 'wear.' Choice A is incorrect as 'seen' should be 'saw,' which is the correct past tense of 'see.' Choice B is incorrect as 'sung' should be 'sang,' the correct past tense of 'sing.' Choice C is incorrect as 'ran' is the correct verb, but the question specifically asks for the correct use of a verb, not just any verb.

5. What does Depth mean?

A. The thickness of an object
B. Downward measurement from a surface
C. The length of a surface
D. The area between two points

Correct answer: B

Rationale: Depth refers to the distance or downward measurement from a surface. It is not the thickness of an object (Choice A), as thickness is the measure of how thick or thin an object is, not necessarily related to depth. Additionally, it is not the length of a surface (Choice C) because length typically refers to the longest dimension of an object rather than its depth. Finally, it is not the area between two points (Choice D) because area is a measure of the space within a boundary defined by points, while depth specifically refers to the vertical distance below a surface.
