HESI A2 Vocabulary 2023
1. Which word describes a screen or filter?
- A. Permeable
- B. Incendiary
- C. Exuding
- D. Resilient
Correct answer: A
Rationale: The word 'permeable' refers to a material or surface that allows liquids, gases, or substances to pass through it, while screening or filtering out impurities. This makes it an appropriate descriptor for a screen or filter, which function by allowing certain elements to pass through while retaining others. Choices B, C, and D are incorrect: 'Incendiary' means causing fires, 'Exuding' means giving off or releasing, and 'Resilient' means able to withstand or recover from difficult conditions.
2. What is the meaning of impugn?
- A. To instill with
- B. To instruct about
- C. To dispute the truth of
- D. To lament or complain about
Correct answer: C
Rationale: The word 'impugn' means to challenge or attack the truth, integrity, validity, or honesty of something. It is not related to instilling (A), instructing (B), lamenting, or complaining (D). Impugn specifically involves questioning the accuracy or validity of a statement or argument, making choice C the correct answer.
3. What does bifurcate mean?
- A. Fold twice
- B. Flower biannually
- C. Divide in two forks
- D. Pierce two openings
Correct answer: C
Rationale: Bifurcate means to divide into two forks or branches. It comes from the Latin word "bi" meaning two and "furca" meaning fork. So, when something bifurcates, it splits into two separate paths or divisions. Choice A, "Fold twice," is incorrect as bifurcate doesn't involve folding. Choice B, "Flower biannually," is unrelated to the meaning of bifurcate. Choice D, "Pierce two openings," is also incorrect as it does not capture the true essence of bifurcate, which is about dividing into two forks or branches.
4. Choose the meaning of the word 'tremulous' in the following sentence: 'The patient held out a tremulous hand and grasped the paperwork.'
- A. Wrinkled and wizened
- B. Pale and lifeless
- C. Clenched and arthritic
- D. Quivering and weak
Correct answer: D
Rationale: In this sentence, the word 'tremulous' is used to describe the patient's hand. When someone's hand is described as tremulous, it means it is quivering or shaking, indicating weakness or distress. Therefore, the correct meaning of 'tremulous' in this context is quivering and weak. Choices A, B, and C are incorrect because they do not capture the specific meaning of 'tremulous' in this context. 'Wrinkled and wizened' refers to being old and withered, 'pale and lifeless' describes a lack of color and vitality, and 'clenched and arthritic' implies a tight grip and joint inflammation, none of which accurately represent the trembling or shaking nature of a tremulous hand.
5. 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.
