Vocabulary HESI A2 Practice Test

1. What does Labile mean?

A. Stable
B. Changing rapidly and often
C. Unchanging
D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

2. 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.

3. What is the best description of the word 'suppress'?

A. stop
B. push up
C. release
D. strain

Correct answer: A

Rationale: The correct answer is A: 'stop.' 'Suppress' means to stop or hold back something. Choice B, 'push up,' is incorrect as it does not accurately reflect the meaning of 'suppress.' Choice C, 'release,' is incorrect as it is the opposite of 'suppress.' Choice D, 'strain,' is also incorrect as it does not capture the meaning of 'suppress.'

4. The interns observed the CONTOURS of the patients' rash. What does Contours mean?

A. Color
B. Shape
C. Size
D. Texture

Correct answer: B

Rationale: The correct answer is B: 'Shape.' Contours refer to the outline or shape of something. In this context, the interns were observing the shape or outline of the patients' rash, not the color, size, or texture. Colors, sizes, and textures are not typically described as contours, making choices A, C, and D incorrect.

5. The mail carrier's job is to put the _____ in every mailbox on the block.

A. letter
B. envelope
C. package
D. documents

Correct answer: B

Rationale: The correct answer is B: 'envelope.' The mail carrier typically delivers envelopes containing mail to every mailbox on the block. Envelopes are commonly used to protect and contain letters, making them the most suitable choice in this context. Choices A, C, and D are incorrect because while the mail carrier may deliver letters, packages, or documents, the most common item placed in mailboxes is an envelope containing mail.
