HESI A2 Grammar Practice Exam

Correct Answer: B

Rationale: The correct answer is B: once. In the sentence, "once" is used incorrectly as it implies the professor was only an intern for a brief period in the past, which may not be true. The sentence suggests the professor was an intern at the hospital in the 1980s, not just for a single instance. The other choices (A, C, D) are used correctly in the context of the sentence, as they refer to the profession, role, and location respectively without any ambiguity or error.

Correct Answer: D

Rationale: The correct answer is D: their. In the sentence, "the nurses' laughter" indicates possession by a plural noun "nurses." Therefore, the possessive pronoun "their" is the most appropriate choice to indicate that the laughter belongs to the nurses collectively. The other choices (A: his, B: hers, C: them) are incorrect because they do not match the plural possessive noun "nurses" in the sentence. "His" and "hers" are singular possessive pronouns, while "them" is a plural objective pronoun.

Correct Answer: C

Rationale: The correct answer is C: our. In the sentence, "The doctor and I went over the doctor's and my notes," the possessive pronoun "our" is the best substitute for "the doctor's and my." This is because "our" indicates joint ownership, which is appropriate in the context of both individuals sharing notes. The possessive pronouns "his" (A), "their" (B), and "mine" (D) do not accurately reflect the shared ownership implied in the sentence. "His" and "their" suggest singular and plural ownership, respectively, while "mine" implies sole possession by one person.

Correct Answer: A

Rationale: The correct answer is A: volunteered. In the sentence, "the first time she volunteered at the hospital," the verb should be in the past tense to match "the first time." "Volunteered" is the correct past tense form of the verb "volunteer" in this context. Choice B: volunteering is in the present participle form and does not fit the past tense requirement. Choice C: was volunteered is in the passive voice and does not make sense in the context of Cathy actively asking questions. Choice D: volunteer is in the base form and does not match the past tense needed in the sentence.

Correct Answer: A

Rationale: The correct answer is A: spoke to the patient's parents. The sentence is in past tense ("had"), so the verb should also be in the past tense to maintain grammatical consistency. "Spoke" is the correct past tense form of the verb "speak." Choices B, C, and D are incorrect because they use present or future tenses, which do not match the past tense of the sentence. The verb should agree with the tense of the main verb in the sentence for grammatical correctness.
