HESI A2 Grammar Practice Exam

Correct Answer: C

Rationale: The correct answer is C: them. In the sentence, "The children and them performed a skit for the elderly patients," the pronoun "them" is used to refer to a group of people (children and others). The pronoun "them" is the objective form of the pronoun "they" and is used to represent the object of the sentence. In this case, the children and other individuals are the ones performing the skit, making "them" the appropriate choice. Choice A: "he" is incorrect as it would refer to a singular male individual, not a group. Choice B: "me" is incorrect as it is the objective form of the pronoun "I" and does not fit the subject of the sentence. Choice D: "her" is incorrect as it is the objective form of the pronoun "she" and does not match the subject of the sentence.

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 punctuation needed in the sentence is a comma (Choice B). The comma is used to separate the dependent clause "Because of a major accident on the freeway" from the independent clause "the emergency room was overcrowded." This creates a clear and correct sentence structure. A period (Choice A) would create two separate sentences, which is not necessary in this case. An exclamation point (Choice C) is inappropriate as the sentence is not expressing excitement or strong emotion. A semicolon (Choice D) is not suitable as the clauses are not closely related or part of a list.

Correct Answer: B

Rationale: The correct answer is B: Comma. In the sentence "The days seem long, but the nights seem even longer," a comma is needed before the coordinating conjunction "but" to separate the two independent clauses. This comma helps clarify the relationship between the two contrasting ideas. Choices A, C, and D are incorrect because a period would create two short, choppy sentences, a colon is not needed for this context, and an apostrophe is used for possession or contractions, which are not relevant in this 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.
