HESI A2 Vocabulary 2023
1. To aspirate fluid, you might use a ___________.
- A. syringe
- B. beaker
- C. test tube
- D. flange
Correct answer: A
Rationale: To aspirate fluid, you would typically use a syringe. A syringe is a device consisting of a tube and a plunger, which allows you to draw fluids such as blood or medication into the tube by pulling back on the plunger. This action is called aspiration, and the syringe is a common tool for this purpose in various medical procedures. Choices B, C, and D are incorrect as they are not typically used for aspiration procedures. A beaker is a glass container used for holding liquids, a test tube is used for holding or mixing small quantities of substances, and a flange is a projecting rim or edge used for strength or for attaching to another object.
2. What is the meaning of exacerbate?
- A. To lessen in intensity
- B. To make worse
- C. To neutralize
- D. To control
Correct answer: B
Rationale: The correct answer is B: 'To make worse.' Exacerbate means to worsen or make a situation, condition, or problem more severe or intense, not to lessen it. Therefore, if something exacerbates a situation, it means it makes it worse. Choices A, C, and D are incorrect because exacerbate does not mean to lessen in intensity, neutralize, or control the situation, but rather to worsen it.

Rationale: In the context of the sentence provided, efficacy refers to the ability of counterfeit medicines to produce the intended or desired effect. Efficacy is closely related to effectiveness, which is the correct description in this context.

- A. Ability to speak

Choices A, B, and D are incorrect because 'equilibrium' specifically refers to balance, not the ability to speak, sense of taste, or ability to swallow.

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