HESI A2 Grammar Practice Exam

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: C

Rationale: The correct answer is C: our. In the sentence, "The doctor and I went over the doctor's and my notes," the possessive pronoun "our" is the best substitute for "the doctor's and my." This is because "our" indicates joint ownership, which is appropriate in the context of both individuals sharing notes. The possessive pronouns "his" (A), "their" (B), and "mine" (D) do not accurately reflect the shared ownership implied in the sentence. "His" and "their" suggest singular and plural ownership, respectively, while "mine" implies sole possession by one person.

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.

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: C

Rationale: The correct answer is C: boys'. In this sentence, the possessive form of "boys" should be "boys's" to indicate that the pranks belonged to the four boys. The incorrect use of the apostrophe after "boys" in choice C makes it the misspelled word. "Everyone" (choice A), "fraternity" (choice B), and "sophomoric" (choice D) are spelled correctly in the context of the sentence.
