HESI A2 Vocabulary Quiz
1. Choose the meaning of the word inhibiting in the following sentence: 'This medication works by inhibiting the action of a certain enzyme.'
- A. Occupying
- B. Speeding
- C. Hindering
- D. Enhancing
Correct answer: C
Rationale: Inhibiting means to prevent, restrain, or impede. In the context of the sentence, inhibiting the action of a certain enzyme refers to hindering or slowing down the enzyme's activity. Choice A ('Occupying') is incorrect as inhibiting does not mean taking up space. Choice B ('Speeding') is incorrect as inhibiting does not mean to accelerate. Choice D ('Enhancing') is incorrect as inhibiting is the opposite of enhancing.
2. Which sentence correctly uses the word 'affect'?
- A. The medication had no effect on the patient's symptoms
- B. The noise did not affect his sleep
- C. The bright light will affect your eyes
- D. The cold weather did not affect her mood
Correct answer: B
Rationale: The correct use of 'affect' is to show influence or make a difference. In this context, 'The noise did not affect his sleep' is the correct usage as noise can impact one's ability to sleep. Choice A is incorrect as 'affect' is commonly confused with 'effect.' Choice C is incorrect as 'affect' is not typically used to refer to the impact of light on eyes. Choice D is incorrect as 'affect' is not typically used to describe the impact of weather on mood.
3. Did the interns contravene the doctor's orders?
- A. Follow
- B. Disregard
- C. Exceed
- D. Respect
Correct answer: B
Rationale: The correct answer is 'B: Disregard.' Contravene means to violate or disregard rules or orders. In this context, the question is asking whether the interns went against or disobeyed the doctor's orders. Choices 'A: Follow,' 'C: Exceed,' and 'D: Respect' do not align with the meaning of contravene in this context. Following, exceeding, or respecting the doctor's orders would mean the interns did not contravene them.
4. What is the meaning of Contingent?
- A. Certain
- B. Dependent
- C. Unrelated
- D. Guaranteed
Correct answer: B
Rationale: The correct meaning of 'contingent' is dependent, indicating reliance on something else. Choice A, 'Certain,' is incorrect as it means clearly established or assured, which does not align with the meaning of 'contingent.' Choice C, 'Unrelated,' is also incorrect as it means not connected or associated with, which is a different concept. Choice D, 'Guaranteed,' is not synonymous with 'contingent' as it implies assurance or confirmation, not dependency.
5. 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.
