HESI A2 Vocabulary 2023

1. A stye is an infection of the ___________.

A. eyelid
B. eardrum
C. nostril
D. scalp

Correct answer: A

Rationale: A stye is an infection that occurs at the base of an eyelash or on the eyelid. It is typically caused by a bacterial infection, leading to redness, swelling, and sometimes discomfort in the affected area. Choices B, C, and D are incorrect because a stye specifically refers to an infection of the eyelid area, not the eardrum, nostril, or scalp.

2. 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.

3. What does the quoted word 'cornucopia' mean in the following sentence?

A. Plethora
B. Ostracism
C. Laborious
D. Pensive

Correct answer: A

Rationale: The correct answer is A: 'Plethora.' In the context provided, 'cornucopia' is used metaphorically to signify an abundance or a large variety of stimulating questions and conversation. 'Plethora' is a synonym for 'cornucopia' and means an excessive amount or abundance. Choices B, C, and D are incorrect. 'Ostracism' means exclusion or rejection, 'Laborious' means requiring a lot of effort, and 'Pensive' means engaged in deep thought.

4. Long before his death, Pablo Picasso became one of the most important artists in history.

A. become
B. became
C. been
D. had become

Correct answer: B

Rationale: The correct answer is 'Became.' In this sentence, we need the simple past tense 'became' to describe the action that occurred in the past. 'Become' (choice A) is incorrect as it is the base form of the verb and doesn't fit the sentence structure. 'Been' (choice C) is incorrect as it is the past participle and doesn't match the sentence context. 'Had become' (choice D) is unnecessary as the sentence doesn't require the past perfect tense.

5. What does 'Cease' mean?

A. Start
B. Come to an end
C. Pause
D. Skip

Correct answer: B

Rationale: The correct answer is B: 'Come to an end.' Cease means to stop or come to an end. Choice A, 'Start,' is the opposite of what Cease means. Choice C, 'Pause,' implies a temporary stop, which is not the same as coming to an end. Choice D, 'Skip,' means to omit or bypass, which is different from the meaning of Cease.
