Quizlet Vocabulary HESI A2

1. 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.

2. A restricted diet is ___________.

A. low in fat
B. vegetarian
C. banned
D. limited

Correct answer: D

Rationale: A restricted diet is limited in some way, such as reducing the intake of certain foods, food groups, or nutrients. It may involve limitations on quantity, frequency, or types of foods consumed. This restriction could be related to health factors, allergies, sensitivities, ethical reasons, or personal preferences. Choice A, 'low in fat,' is too specific and does not encompass the broad concept of restriction in a diet. Choice B, 'vegetarian,' refers to a specific dietary pattern but does not necessarily indicate restriction. Choice C, 'banned,' is incorrect as it implies a complete prohibition rather than limitation, which is characteristic of a restricted diet.

3. If a theory is obsolete, what is true of it?

A. Up to date
B. Outdated
C. Innovative
D. Scientific

Correct answer: B

Rationale: The correct answer is B: 'Outdated.' When something is described as 'obsolete,' it means that it is outdated or no longer in use. Therefore, an obsolete theory is no longer current or relevant. Choices A, C, and D are incorrect because an obsolete theory is not considered up to date, innovative, or necessarily scientific; it is outdated and no longer relevant in its field.

4. Which term best describes a synthetic drug?

A. man-made
B. phony
C. atypical
D. futile

Correct answer: A

Rationale: A synthetic drug is one that is artificially created in a laboratory setting rather than occurring naturally. The term 'man-made' accurately describes this process. Choices B, C, and D are incorrect. 'Phony' means fake or fraudulent, not specifically related to synthetic drugs. 'Atypical' means unusual or not typical, which doesn't directly relate to how synthetic drugs are made. 'Futile' means pointless or ineffective, which is not a characteristic of synthetic drugs.

5. Select the meaning of the word 'residual' in the sentence. Something that remains is referred to as __________.

A. Resident
B. Residual
C. Resistance
D. Resin

Correct answer: B

Rationale: The correct answer is 'B: Residual.' In the given sentence, 'residual' is used to describe something that is left or remaining. 'Residual' fits the context perfectly as it aligns with the definition of what remains. The other choices are incorrect: A) 'Resident' refers to a person living in a specific place, C) 'Resistance' is the act of opposing or withstanding something, and D) 'Resin' is a sticky substance produced by plants.
