HESI A2 Grammar Practice Exam

Correct Answer: D

Rationale: The correct answer is D, "their." In the sentence, "their" is used incorrectly because it is a possessive pronoun, but it doesn't have a noun to show possession. The sentence should be "The boys leapt up, happy to assist their favorite teacher." The other choices (A, B, C) are used correctly in the sentence and are essential to convey the intended meaning. Choice A, "leapt," is a past tense verb that correctly describes the action of the boys jumping up. Choice B, "happy," is an adjective that correctly describes the boys' emotional state. Choice C, "assist," is a verb that correctly describes the action the boys are willing to take.

Correct Answer: C

Rationale: The correct answer is C: "had rarely". This is incorrect as it should be "rarely had" to follow correct word order for adverbs of frequency. "Had rarely" is an incorrect placement of the adverb in the sentence structure. "Before their" (A) is correct as it introduces a time frame. "Children had" (B) is also correct as it identifies the subject and tense. "Rarely eat" (D) is incorrect as it changes the tense and does not match the past perfect tense used in the sentence.

Correct Answer: B

Rationale: The correct answer is B: lead. In the sentence, the correct past tense form of "lead" should be "led" as it is referring to a past action. "Lead" is the present tense form, while "led" is the past tense form. A: attending, C: entourage, and D: interns are all spelled correctly and are appropriate in the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: principle. In the sentence, the word should be "principal" to refer to the main or leading role. "Principle" refers to a fundamental truth or belief. The other choices, B: role, C: provision, and D: convenient are all spelled correctly and fit appropriately in the sentence context.

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.
