HESI A2 Grammar Practice Exam

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: A

Rationale: The correct answer is A: her. In the sentence, "her" is the possessive pronoun that correctly refers to the nurse. The sentence indicates that the paperwork belonged to the nurse, so the possessive pronoun "her" is the most suitable choice. B: "he" is incorrect as it refers to a male subject, which doesn't match the context of the sentence. C: "his" is incorrect as it is used for a male possessive pronoun, not suitable for referring to the nurse. D: "it" is incorrect as it is a neutral pronoun and does not correctly show possession by the nurse in this context.

Correct Answer: C

Rationale: The correct answer is C: "and new tires." This phrase is misplaced because it disrupts the parallel structure of the sentence. The sentence is about the car's characteristics (white roof) and ownership (belongs to our friends). The phrase "and new tires" should follow the white roof to maintain parallelism. Choices A, B, and D are all correctly placed within the sentence and contribute to its clarity and coherence.

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: 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.
