HESI A2 Grammar Practice Exam

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: 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.

Correct Answer: C

Rationale: The correct answer is C: "and new tires." This phrase is misplaced because it disrupts the parallel structure of the sentence. The sentence is about the car's characteristics (white roof) and ownership (belongs to our friends). The phrase "and new tires" should follow the white roof to maintain parallelism. Choices A, B, and D are all correctly placed within the sentence and contribute to its clarity and coherence.

Correct Answer: C

Rationale: The correct answer is C: taking. In this sentence, "taking" is the present participle form and is used to show an ongoing action that occurred before the main action (patient sleeping). "Having taken" would imply the action of taking the pill occurred before the patient slept. The other choices are incorrect because: A: "took" is simple past tense, not fitting the structure of the sentence. B: "take" is the base form, not showing the correct tense or form. D: "taken" is the past participle form, but it doesn't convey the ongoing action needed in this context.

Correct Answer: C

Rationale: The correct answer is C: herself. In the sentence, "Mary Ann gave herself credit for studying so hard and passing the test," the reflexive pronoun "herself" refers back to the subject "Mary Ann." This usage indicates that Mary Ann is giving credit to herself, making the sentence grammatically correct. Choice A (oneself) is incorrect because it is a generic reflexive pronoun that does not agree with the feminine subject "Mary Ann." Choice B (itself) is incorrect because it refers to inanimate objects, not a person like Mary Ann. Choice D (themselves) is incorrect because it is plural and does not agree with the singular subject "Mary Ann."
