Vocabulary HESI A2 Practice Test

1. What does Labile mean?

A. Stable
B. Changing rapidly and often
C. Unchanging
D. Rarely changing

Correct answer: B

Rationale: Labile means something that changes rapidly and often. In this context, 'Stable' (Choice A) is the opposite of labile, 'Unchanging' (Choice C) and 'Rarely changing' (Choice D) do not capture the essence of labile. Labile is specifically used to describe something that is easily altered, constantly changing, or unstable, hence the most suitable choice is 'Changing rapidly and often' (Choice B).

2. If a pharmacy is in compliance, it __________.

A. shows flexibility
B. receives criticism
C. meets requirements
D. has been disciplined

Correct answer: C

Rationale: When a pharmacy is in compliance, it means that it is meeting all the necessary requirements in terms of regulations, standards, and guidelines. Compliance indicates that the pharmacy is following the established rules and procedures to ensure the safety and quality of its services, products, and operations. Choices A, B, and D are incorrect because compliance does not imply flexibility, criticism, or discipline; rather, it signifies adherence to set regulations and standards.

3. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?

A. Fallback
B. Substitute
C. Control
D. Curative

Correct answer: C

Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.

4. Which sentence is NOT GRAMMATICALLY CORRECT?

A. Because he did not examine the patient, the healthcare provider prescribed her with the wrong medication.
B. The nurse decided to bathe the client, then trim his nails.
C. The dietician, through negligence, made a mistake with the diet plan.
D. Since the child was feeling ill, the nurse sent him home.

Correct answer: B

Rationale: Choice B is incorrect due to the use of 'than' instead of 'then.' The correct word in this context is 'then' to indicate the order of actions. Choices A, C, and D are all grammatically correct. In choice A, the sentence structure is correct with a clear cause-effect relationship. Choice C is grammatically sound, describing the dietician's mistake. Choice D is also grammatically correct, showing a cause (the child feeling ill) leading to an effect (the nurse sending him home).

5. What does 'Flushed' refer to?

A. Swollen
B. Reddened or ruddy appearance
C. Discolored
D. Pale

Correct answer: B

Rationale: The correct answer is B: 'Reddened or ruddy appearance.' When someone is flushed, it means they have a red or ruddy complexion, often due to embarrassment, anger, or a physical reaction. Choices A, C, and D are incorrect because 'flushed' specifically refers to a red or ruddy appearance, not swelling, discoloration, or paleness.
