HESI A2 Grammar Practice Exam

Correct Answer: B

Rationale: The correct answer is B: once. In the sentence, "once" is used incorrectly as it implies the professor was only an intern for a brief period in the past, which may not be true. The sentence suggests the professor was an intern at the hospital in the 1980s, not just for a single instance. The other choices (A, C, D) are used correctly in the context of the sentence, as they refer to the profession, role, and location respectively without any ambiguity or error.

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: therapist. In this sentence, the word "therapist" is used incorrectly because it is redundant with the word "counselor." A therapist and a counselor are essentially the same role, providing emotional support and guidance. Therefore, using both terms in this context is unnecessary and redundant. The word "therapist" should be replaced with a different term, such as "doctor" or "psychologist," to convey a different role or specialization. The other choices (A, B, D) are used correctly in the sentence and do not present any errors in terms of grammar or meaning.

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: 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.
