HESI A2 Grammar Practice Test

Correct Answer: A

Rationale: The correct answer is "A: them." In this sentence, "them" is used to refer back to Silvio's family, making the sentence more concise and clear. The pronoun "them" is the appropriate choice as it maintains clarity and avoids repetition. Choice B, "us," would change the meaning of the sentence as it would refer to the nurse and the speaker, not Silvio's family. Choice C, "they," is incorrect as it does not correctly refer to Silvio's family. Choice D, "those," is also incorrect as it does not serve as a suitable pronoun to replace Silvio's family.

Correct Answer: B

Rationale: The correct answer is B: Comma. The sentence "Follow my lead, I have been performing this procedure for years" is a compound sentence with two independent clauses. A comma is needed before the conjunction "I" to separate the two independent clauses correctly. Using a period (A) would create two separate sentences. Using an exclamation point (C) would be inappropriate as the sentence is not expressing strong emotion. A semicolon (D) could be used, but a comma is more commonly used to connect two closely related independent clauses.

Correct Answer: C

Rationale: The correct answer is C: her. In this sentence, "Roseanne" is a singular noun, so the possessive pronoun "her" should be used to show ownership. "She" (choice A) is a subject pronoun, "their" (choice B) is a plural pronoun, and "hers" (choice D) is a possessive pronoun used without a noun. Therefore, "her" is the most suitable choice to maintain clarity and grammatical correctness.

Correct Answer: B

Rationale: The correct answer is B: too. In this context, "too" means excessively or overly, indicating that the person is overly uncomfortable. Using "to" (choice A) would not convey the intended meaning. Choice C, "much," is not suitable as it does not fit grammatically in the sentence. Choice D, "lesser," is incorrect as it does not make sense in the context of the sentence. Therefore, "too" is the correct choice to convey the idea of excessive discomfort in the sentence.

Correct Answer: C

Rationale: The correct answer is C: study. In the sentence, "study" should be "studies" to match the singular subject Sidney. The verb should agree with the subject in number, so it should be "Sidney studies for the exam." A: "practices" is correct as it agrees with the subject Jack. B: "while" is used correctly as a conjunction to show simultaneous actions. D: "exam" is used correctly as the object of the preposition "for."
