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. What punctuation is needed in the following sentence to make it correct? Have you finished reading the lab results so we can schedule an appointment with the patient?

Correct answer: C

Rationale: The correct punctuation needed in the sentence is a question mark. The sentence is a question, asking whether the lab results have been read in order to schedule an appointment. Therefore, a question mark is needed at the end of the sentence to indicate that it is an inquiry. The period is used for statements, not questions. A comma would not be appropriate here as the sentence is not a list or a compound sentence. An exclamation mark would imply excitement or surprise, which is not the tone of the sentence.

3. What word is best to substitute for the underlined words in the following sentence? Mr. Menotti’s wife collected Mr. Menotti’s belongings for the ride home.

Correct answer: D

Rationale: The word 'his' is the possessive form of the pronoun 'Mr. Menotti,' indicating that the belongings belong to him. Using 'her,' 'him,' or 'he' would not be grammatically correct in this context as they do not reflect the possession by Mr. Menotti. 'Her' would imply the belongings belong to his wife, 'him' is an objective pronoun, and 'he' is a subject pronoun, neither of which correctly shows possession.

4. Select the word in the following sentence that is not used correctly. Try not to lose patience or suffer a drop in morale.

Correct answer: A

Rationale: The word 'lose' in the sentence is not used correctly. The correct word should be 'lose,' which means to be deprived of or to fail to maintain possession of something. 'Loose' means not tight or free from restraint. In this context, 'lose' is the appropriate term to convey the idea of not maintaining patience or morale.

5. Which word is not spelled correctly in the context of the following sentence? The counselor expected me to accept her advice without question.

Correct answer: A

Rationale: The word 'counselor' is spelled correctly in the sentence. The word 'advise' in the sentence should be spelled 'advice.' 'Advise' is a verb meaning to offer suggestions, while 'advice' is a noun referring to recommendations or guidance given by someone. In this context, the correct word to use is 'advice,' as the sentence implies the counselor's guidance rather than her action of advising. Choice A is the correct answer as it is the only word that is not spelled correctly in the given sentence.
