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. If a patient is especially obdurate, she is ___________.

Correct answer: B

Rationale: The correct answer is B: 'quite stubborn.' The word 'obdurate' means stubbornly refusing to change one's opinion or course of action. Therefore, if a patient is especially obdurate, it indicates that she is likely very stubborn in her behavior or beliefs. Choices A, C, and D are incorrect because they do not reflect the meaning of 'obdurate.' Being 'very large' (Choice A), 'easily upset' (Choice C), or 'ready to go home' (Choice D) does not directly relate to being stubborn and unwilling to change.

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

Correct answer: C

Rationale: The correct answer is C: 'Sense of balance.' In the sentence provided, 'equilibrium' refers to a state of physical balance or stability. The client lost his balance when he woke up, indicating a loss of stability or equilibrium. Choices A, B, and D are incorrect because 'equilibrium' specifically refers to balance, not the ability to speak, sense of taste, or ability to swallow.

4. Which word names a medicine whose purpose is to induce vomiting?

Correct answer: B

Rationale: The correct answer is B, 'Emetic.' An emetic is a medication specifically designed to induce vomiting. This helps the body expel toxic substances or clear the stomach. Choice A, 'Laxative,' aids in relieving constipation by promoting bowel movements, not inducing vomiting. Choice C, 'Vaccine,' is a substance used to stimulate the immune system against specific diseases, not to induce vomiting. Choice D, 'Analgesic,' refers to a medication used to relieve pain, not to induce vomiting. Therefore, options A, C, and D are incorrect in the context of inducing vomiting.

5. What is the meaning of the word 'proscribe'?

Correct answer: D

Rationale: The correct answer is D: 'forbid.' 'Proscribe' means to officially forbid or prohibit something. Choice A, 'anticipate,' is incorrect as it means to expect or predict something. Choice B, 'prevent,' is incorrect as it means to stop something from happening. Choice C, 'defeat,' is incorrect as it means to overcome or win against someone or something, which is not the meaning of 'proscribe.' Therefore, the most appropriate meaning for 'proscribe' among the given choices is to forbid.
