Vocabulary for HESI A2

1. The quality, safety, and efficacy of the new medicines are not known. What does efficacy mean?

Correct answer: B

Rationale: Efficacy refers to how effective something is. In this context, it refers to the effectiveness of the new medicines. 'Cost' (Choice A) is incorrect as it relates to the price of something, not its effectiveness. 'Quality' (Choice C) is incorrect as it refers to the standard or degree of excellence. 'Usage' (Choice D) is incorrect as it refers to how something is used, not its effectiveness.

2. After the policeman _____ for several miles, he finally caught up with the man who had stolen the purse.

Correct answer: B

Rationale: In this sentence, the correct option is 'had run' as it is the past perfect tense, which is used to indicate an action completed before another past action. The sentence structure requires the past perfect form to show that the running occurred before catching up with the man. 'Ran' (choice A) is in simple past tense and does not convey the sequence of events correctly. 'Chased' (choice C) is the simple past tense of the verb 'chase' and does not align with the past perfect tense needed in the sentence. 'Drove' (choice D) is incorrect as it refers to using a vehicle to pursue someone, whereas the context of the sentence indicates running on foot.

3. Which word is not spelled correctly in the sentence: 'The physician thought it was unnecessary to explain the procedure.'

Correct answer: B

Rationale: The word 'unnecessary' is misspelled as 'unecessary' in the sentence. The correct spelling should have double 'n' as in 'unnecessary'. Choice A, C, and D are spelled correctly in the sentence provided.

4. A condition that is chronic is ___________.

Correct answer: D

Rationale: The correct answer is D, 'recurring.' A chronic condition is one that is ongoing or long-lasting, implying that it persists or recurs over a prolonged period of time. Choices A, B, and C are incorrect because chronicity does not necessarily imply harmlessness, criticality, or contagion; rather, it refers to the persistent or recurring nature of the condition.

5. What is the CORRECT CONTRACTION for 'They are'?

Correct answer: B

Rationale: The correct contraction for 'They are' is 'They're.' 'Their' is a possessive pronoun indicating ownership, not a contraction. 'The're' is not a valid contraction. 'No contraction used' is incorrect as there is a contraction for 'They are,' which is 'They're.'
