HESI A2
Vocabulary HESI A2 Practice Test
1. What does Abstain mean?
- A. To voluntarily refrain from something
- B. To consume something
- C. To eat
- D. To encourage
Correct answer: A
Rationale: The correct answer is A: 'To voluntarily refrain from something.' Abstain means to choose not to do or have something, especially something you like or enjoy. Choices B, C, and D are incorrect because abstain does not mean to consume something, to eat, or to encourage. It specifically refers to the act of voluntarily refraining from an action or practice.
2. What does Consistency refer to?
- A. Color of a fluid
- B. Degree of viscosity, how thick or thin a fluid is
- C. Taste of a fluid
- D. Smell of a fluid
Correct answer: B
Rationale: Consistency refers to the degree of viscosity of a fluid, indicating how thick or thin it is. Viscosity is the resistance of a fluid to flow, and it determines its consistency. Choices A, color, C, taste, and D, smell, are not related to consistency. Color, taste, and smell are sensory attributes that do not define the physical property of consistency in fluids.
3. The development of the disease was INSIDIOUS.
- A. Momentous
- B. Sudden
- C. Innocuous
- D. Gradual
Correct answer: D
Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.
4. What does it mean if a theory is obsolete?
- A. Advanced
- B. Outdated
- C. Useful
- D. Innovative
Correct answer: B
Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.
5. 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.
