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. The quality, safety, and efficacy of the new medicines are not known. What does efficacy mean?
- A. Cost
- B. Effectiveness
- C. Quality
- D. Usage
Correct answer: B
Rationale: Efficacy refers to how effective something is. In this context, it refers to the effectiveness of the new medicines. 'Cost' (Choice A) is incorrect as it relates to the price of something, not its effectiveness. 'Quality' (Choice C) is incorrect as it refers to the standard or degree of excellence. 'Usage' (Choice D) is incorrect as it refers to how something is used, not its effectiveness.
3. Select the sentence in which 'snake' is used as a verb.
- A. The snake is in the grass
- B. He had to snake his way through the crowd
- C. The snake slithered away
- D. The spy had to snake his way onto the train
Correct answer: D
Rationale: The sentence 'The spy had to snake his way onto the train' correctly uses 'snake' as a verb. In this context, 'snake' is used to describe the spy's action of moving cunningly and stealthily, similar to how a snake slithers, making it the appropriate choice where 'snake' functions as a verb. The other choices use 'snake' as a noun to refer to the reptile itself or its movement, not as a verb.
4. What does the term 'residual' refer to in the following sentence? The nurse was asked to record the residual urine in the patient's bladder.
- A. Measurement
- B. What is left
- C. Total volume
- D. Color and clarity
Correct answer: B
Rationale: The term 'residual' refers to what is left after the main part has been taken or used. In this context, 'residual urine' specifically means the urine that remains in the bladder after urination. Choices A, C, and D do not accurately capture the meaning of 'residual' in this sentence. 'Measurement' (A) is too general, 'Total volume' (C) does not specifically pertain to what remains, and 'Color and clarity' (D) is unrelated to the concept of what is left.
5. What is the best description of the phrase 'suggests that' in this sentence? A study suggests that vaping may reduce cigarette smoking but also lead to higher relapse.
- A. Makes a suggestion about
- B. Gives evidence about
- C. Hints at the idea that
- D. Promotes a plan to
Correct answer: A
Rationale: The correct answer is A: 'Makes a suggestion about.' The phrase 'suggests that' indicates that the study is proposing or indicating the possibility that vaping may have certain effects on cigarette smoking. It is not stating a fact or providing evidence, but rather making a suggestion or recommendation about the relationship between vaping and cigarette smoking. Choices B, C, and D are incorrect because the phrase 'suggests that' does not provide evidence, hint at an idea, or promote a plan, but rather presents a suggestion or possibility.
