HESI A2 Grammar Practice Exam

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: "had texted me on my cell phone." This is the correct choice because the sentence starts with "Before," indicating a past event that occurred before another past event. Using the past perfect tense "had texted" correctly indicates that James sent the text before the speaker finished supper. Choice A is incorrect because it uses the present tense "is texting," which does not match the past context of the sentence. Choice C is incorrect because it uses the present tense "texts," which also does not match the past context. Choice D is incorrect because it uses the present participle "texting," which is not suitable for indicating a completed action before another past event.

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: A

Rationale: The correct answer is A: stealthy. In the sentence, "stealthily" should be used instead of "stealthily" to modify the verb "moving." Stealthily is an adverb that describes the action of moving in a sneaky or secretive manner. The adverb form is needed to modify the verb “moving” in this sentence. The other choices (B: sneaky, C: reached, D: topmost) are all used correctly in the sentence. "Sneaky" appropriately describes the boy's behavior, "reached" is the correct past tense of the verb "reach," and "topmost" correctly indicates the position of the shelf.

Correct Answer: B

Rationale: The correct answer is B: subscribes. In the sentence, "One out of four doctors" is the subject, which is singular. Therefore, the verb should also be singular to match, making "subscribes" the correct form. Choice A, subscribe, is incorrect because it is the plural form. Choice C, subscribing, is incorrect as it is a present participle and does not match the subject. Choice D, are subscribed, is incorrect as it is in the plural form and passive voice, which does not fit the sentence structure.
