HESI A2 Vocabulary 2024

1. Choose the meaning of the word 'adverse' in the following sentence: 'Occasionally, this medicine causes an adverse reaction.'

Correct answer: A

Rationale: The word 'adverse' in the sentence is most closely aligned with the meaning of 'unfavorable.' An adverse reaction to a medicine signifies a negative or harmful response, which supports the definition of unfavorable. Choice B, 'Contrary,' does not accurately capture the negative connotation associated with 'adverse.' Choice C, 'Noticeable,' does not reflect the meaning in the context provided. Choice D, 'Startling,' suggests a more sudden or surprising nature, which is not the primary meaning of 'adverse' in this context.

2. Select the correct definition of the word 'prognosis' in the sentence: 'The doctor’s prognosis gave the patient reason to feel optimistic.'

Correct answer: D

Rationale: In the context provided, 'prognosis' refers to a doctor's prediction or statement about the likely outcome of a disease or condition. This makes 'Outcome statement' the correct choice. 'Instructions' (A) are not related to prognosis. 'Estimate' (B) is a rough calculation or approximation, not a prediction of an outcome. 'Behavior' (C) refers to actions, conduct, or manner of an individual, which is not the meaning of 'prognosis' in this sentence.

3. Select the meaning of the underlined word in the following sentence. What is the prognosis for those accident victims?

Correct answer: A

Rationale: In this sentence, the word 'prognosis' refers to the expected outcome or forecast for the accident victims. It indicates what is likely to happen in terms of their recovery or overall condition following the accident. Therefore, the correct meaning of the underlined word is the expected outcome, which is option A. Choices B, C, and D are incorrect because 'prognosis' does not refer to a treatment option or fabrication.

4. What is the best description for the word efficacy in the following sentence? The quality, safety, and efficacy of counterfeit medicines are not known.

Correct answer: A

Rationale: In the context of the sentence provided, efficacy refers to the ability of counterfeit medicines to produce the intended or desired effect. Efficacy is closely related to effectiveness, which is the correct description in this context. 'Significance' (Choice B), 'Corollary' (Choice C), and 'Conclusion' (Choice D) do not accurately capture the meaning of efficacy in this context.

5. What is the meaning of Gender?

Correct answer: B

Rationale: Gender refers to the biological and social characteristics that define male and female identities. It is not a medical condition, emotional state, or psychological term. The term 'gender' specifically relates to the sex of an individual, distinguishing between traits associated with being male or female. Therefore, the correct answer is B.
