Grammar for HESI A2

1. Select the word that makes the following sentence grammatically correct: The centrifuge cannot run by ___________; it requires constant attention.

Correct answer: B

Rationale: The correct answer is 'itself.' The sentence is referring to the centrifuge, which is an object, not a person. Therefore, the word 'itself' is used to indicate that the centrifuge cannot run on its own; it requires constant attention. Choices A, C, and D are incorrect because they refer to a person or people, which is not suitable in the context of the sentence.

2. Identify the dependent clause in this sentence: The mother dog left her bed as soon as the puppies were asleep.

Correct answer: A

Rationale: The correct answer is A: 'As soon as the puppies were asleep' is the dependent clause in the sentence. It functions as an adverbial clause, indicating a time relationship with the action of the mother dog leaving her bed. Dependent clauses rely on independent clauses to form complete sentences and cannot stand alone. Choice B is incorrect because it separates the dependent clause. Choice C is incorrect as it is a noun phrase. Choice D is incorrect as it is an independent clause.

3. What word is best to substitute for the underlined words in the following sentence? You can hear the nurses’ laughter all the way down the hallway.

Correct answer: D

Rationale: The phrase 'the nurses’ laughter' indicates possession by the nurses, a plural subject. Therefore, the appropriate possessive pronoun to use in this context is 'their,' which correctly reflects possession by multiple nurses. Choice A ('his') is singular and refers to a male subject, not suitable for a group of nurses. Choice B ('hers') is singular and refers to a female subject, not suitable for a group of nurses. Choice C ('them') is a pronoun used for a group of people, but it doesn't indicate possession as required in the sentence.

4. Select the word or phrase that makes this sentence grammatically correct. Sadie and her mother were excited to ________ the award.

Correct answer: C

Rationale: The correct answer is 'C: receive.' In this sentence, 'receive' is the infinitive form of the verb that should follow the preposition 'to.' Therefore, the sentence should read: 'Sadie and her mother were excited to receive the award.' 'Be received' (A) is not appropriate in this context as it changes the passive voice. 'Receiving' (B) is a gerund form and does not fit after 'to.' 'Have been received' (D) is in the wrong tense and does not suit the sentence structure.

5. Which word in the following sentence functions as the direct object: 'The nurse helped the patient with the medication'?

Correct answer: C

Rationale: In the sentence 'The nurse helped the patient with the medication,' the direct object is 'patient' because it receives the action of being helped. The direct object typically answers the question 'whom' or 'what' after the verb. In this case, 'the patient' is the one being helped by the nurse, making it the direct object. Choices A, B, and D are incorrect. 'Helped' is the verb, 'nurse' is the subject performing the action, and 'medication' is part of a prepositional phrase and does not directly receive the action of the verb.
