HESI A2 Vocabulary 2023
1. 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.
2. If the sound of the bells could be heard in the entire community, then they could be heard __________.
- A. Thorough
- B. Thought
- C. Through
- D. Throughout
Correct answer: D
Rationale: The word 'throughout' means in every part of a place or thing. In this context, if the sound of the bells could be heard in the entire community, then it implies that the sound could be heard throughout the community, making 'Throughout' the most appropriate answer. Choice A 'Thorough' means complete or absolute, which does not fit the context of the sentence. Choice B 'Thought' is a past tense form of the verb 'think,' which is grammatically incorrect in this sentence. Choice C 'Through' is a preposition and does not convey the intended meaning of being heard in every part of the community.
3. Which sentence is correct?
- A. The physician wrote a prescription for the needed medicine
- B. The physician wrote a recommendation for the needed medicine
- C. The physician wrote a report for the needed medication
- D. The physician wrote a subscription for the needed medication
Correct answer: A
Rationale: A prescription is a written order from a physician or other licensed health practitioner for the preparation and administration of a medication. In this context, 'prescription' is the correct term for the document written by a physician to authorize the dispensing of medication. The other options (B, C, D) use incorrect terms such as 'recommendation,' 'report,' and 'subscription,' which do not accurately convey the action of a physician prescribing medication. Therefore, choice A is the correct answer as it accurately describes the action taken by the physician.
4. Choose the meaning of the word 'dilute' in the following sentence: 'Always dilute that medicine before administering it to a patient.'
- A. Add water to
- B. Reduce by half
- C. Warm up
- D. Decontaminate
Correct answer: A
Rationale: In this context, 'dilute' means to make the medicine less concentrated by adding water or another liquid. It is important to dilute certain medicines to ensure they are safe and effective for a patient's use. Choice B, 'Reduce by half,' is incorrect as diluting does not necessarily mean reducing by half; it means to make less concentrated. Choice C, 'Warm up,' is unrelated to the meaning of dilute. Choice D, 'Decontaminate,' is also incorrect as dilute refers to reducing the concentration of a substance, not removing contaminants.
5. Which of the following is the plural form of the noun 'stimulus'?
- A. Stimulus
- B. Stimuli
- C. Stimulis
- D. Stimula
Correct answer: B
Rationale: The correct answer is 'Stimuli.' When forming the plural of 'stimulus,' the correct form is 'stimuli.' Choice A, 'Stimulus,' is the singular form, not the plural. Choice C, 'Stimulis,' is an incorrect spelling. Choice D, 'Stimula,' is also an incorrect form for the plural of 'stimulus.' Therefore, 'Stimuli' is the only correct plural form.
