HESI A2 Grammar Practice Exam

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: A

Rationale: The correct answer is A: and. In this sentence, the phrase "the windows must be washed" is a continuation of the previous clause "The lounge needs a thorough cleaning." The word "and" is used to connect two related ideas or actions, indicating that both tasks need to be done. The conjunction "or" suggests a choice between cleaning the lounge or washing the windows, which is not the intended meaning. "But" and "yet" would imply a contrast or contradiction between the two tasks, which does not fit the context of 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.

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: 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.
