what does the word ubiquitous mean

HESI A2

Vocabulary HESI A2 Practice Test

1. What does the word UBIQUITOUS mean?

A. Widespread
B. Miniscule
C. Invalid
D. Unit

Correct answer: A

Rationale: The word UBIQUITOUS means something that is found everywhere or is very common. Therefore, the correct meaning for ubiquitous is 'widespread'. 'Miniscule' means very small, 'invalid' means not valid or acceptable, and 'unit' refers to a single entity or component, making them incorrect choices in the context of the word ubiquitous.

2. 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.

3. What is Hydration?

A. The process of dehydrating
B. Maintenance of body fluid
C. Loss of water
D. Draining fluids

Correct answer: B

Rationale: Hydration refers to the maintenance of body fluids. Choice A is incorrect as it describes the opposite process, dehydration. Choice C is incorrect as it focuses on the result of inadequate hydration rather than the concept itself. Choice D is incorrect as it does not accurately define hydration but rather implies removing fluids.

4. What does 'Discrete' mean?

A. Continuous
B. Distinct or separate
C. Mixed
D. Combined

Correct answer: B

Rationale: The correct answer is B, 'Distinct or separate.' Discrete refers to something that is individually separate and distinct, not continuous (choice A), mixed (choice C), or combined (choice D). In mathematics and other fields, discrete items are countable and distinct from each other.

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.
