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 is the best description of the verb emit?

A. To discharge
B. To exclude
C. To dismiss
D. To moderate

Correct answer: A

Rationale: The best description of the verb emit is 'to discharge.' Emit means to produce and release something such as a sound, odor, or substance. Discharge is synonymous with emit in this context as it conveys the idea of releasing or sending out something, which aligns with the meaning of emit. Choices B, C, and D are incorrect. 'To exclude' means to deny access or prevent from entering, which is not the same as emit. 'To dismiss' means to remove from consideration or to let go, which is different from emitting. 'To moderate' means to make or become less extreme, intense, or severe, which is not the same as emitting or releasing something.

3. What does concave mean?

A. Rounded inward
B. Rounded outward
C. Straight
D. Flat

Correct answer: A

Rationale: Concave means rounded inward. When something is concave, it curves inwards like the interior of a bowl. Choice B, 'Rounded outward,' is incorrect as this describes a convex shape, not concave. Choice C, 'Straight,' is incorrect as concave refers to a curved shape, not a straight one. Choice D, 'Flat,' is also incorrect as it does not describe the inward curve characteristic of concave shapes.

4. Choose the meaning of the word 'inquest' in the following sentence: 'Many interesting discoveries were made at the inquest.'

A. Tryout
B. Intake
C. Autopsy
D. Checkup

Correct answer: C

Rationale: The word 'inquest' typically refers to a legal investigation or inquiry, especially into the cause of someone's death. In this context, an 'inquest' is associated with conducting an autopsy to determine the cause of death. Choices A, B, and D are incorrect. A 'tryout' refers to a test or trial, 'intake' relates to the process of taking something in, such as food or air, and a 'checkup' is a general medical examination.

A. dendrite
B. delphic
C. deltoid

The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.
