Vocabulary for HESI A2

1. What is the best meaning of Pernicious?

Correct answer: B

Rationale: The correct answer is B, 'Destructive.' Pernicious is an adjective that describes something that is extremely harmful or destructive. Choice A, 'Harmless,' is the opposite of pernicious. Choice C, 'Helpful,' is a positive term and does not align with the meaning of pernicious. Choice D, 'Harmful,' is a similar term to pernicious but lacks the emphasis on the severe and damaging nature of the word.

2. Which word correctly completes the sentence? "Be careful not to ___ the bottle while you carry it to the table."

Correct answer: B

Rationale: The correct answer is "Break." In this context, 'break' is the appropriate word as it means to damage or shatter something. The other choices are incorrect: 'Brak' is a misspelling, 'Brick' is unrelated to the context of the sentence, and 'Brake' refers to a device used to slow down or stop movement, which is not relevant to carrying a bottle to the table.

3. Choose the meaning of the word 'contravene' in the following sentence: 'Did the interns contravene the doctor’s orders?'

Correct answer: D

Rationale: The word 'contravene' in this sentence means to go against or disobey. Therefore, the correct meaning is closest to 'disregard.' The interns did not follow or comply with the doctor's orders, indicating that they contravened them. 'Comply with' (Choice A) is the opposite of 'contravene,' 'misjudge' (Choice B) and 'comprehend' (Choice C) do not accurately reflect the meaning of 'contravene' in this context.

4. What is another word for acrid?

Correct answer: A

Rationale: Acrid is often used to describe a sharp, unpleasant smell or taste, which is synonymous with bitterness. The word 'bitter' closely relates to the strong and sharp sensation associated with acrid qualities. Choice B, 'Smoky,' does not capture the sharpness or unpleasantness associated with acrid, as it refers more to the presence of smoke. Choice C, 'Nimble,' and choice D, 'Severe,' are unrelated to the meaning of acrid and do not serve as synonyms in this context.

5. Select the meaning of the following phrase. 'A system of procedures to follow.'

Correct answer: A

Rationale: The correct answer is 'Regimen.' 'Regimen' refers to a prescribed set of procedures or a routine, especially related to health. Choice B, 'Regime,' typically refers to a system of government or a ruling period. Choice C, 'Testament,' means a person's will or a statement of belief. Choice D, 'Treatment,' is a medical care given to a patient.
