HESI A2 Grammar Practice Test

Correct Answer: D

Rationale: The correct answer is D: their. In the sentence, "his roommates' housekeeping" indicates possession by more than one person, so the correct possessive pronoun should also be plural. "Their" is the appropriate pronoun to indicate ownership by multiple roommates. Choice A (his) is singular and does not match the plural possession in the sentence. Choice B (hers) is also singular and does not agree with the plural possessive form needed. Choice C (them) is a pronoun for the roommates themselves, not for their possession, making it incorrect in this context.

Correct Answer: A

Rationale: The correct answer is A: Period. A period is needed at the end of the sentence to indicate a complete thought and signal the end of the sentence. In this case, the sentence is a simple statement, so a period is the appropriate punctuation mark. The other choices are incorrect because a comma (B) would create a comma splice, a colon (C) would be unnecessary as the sentence is not introducing a list or explanation, and a semicolon (D) would be too strong of a punctuation mark for this context.

Correct Answer: A

Rationale: The correct answer is A: because. In this sentence, the word "because" indicates the reason why Sheila brought her umbrella to work, linking the forecasted rain to her action. It shows a cause-effect relationship, making it the most fitting word to complete the sentence logically. Explanation: - "Because" provides a clear cause-and-effect relationship between the forecasted rain and Sheila bringing her umbrella. - "Yet" is used to show contrast or unexpected outcome, which doesn't fit the context of the sentence. - "So" is used to show a consequence or result, but it doesn't properly explain why Sheila brought her umbrella. - "Nor" is a coordinating conjunction used in negative constructions, which doesn't make sense in this sentence.

Correct Answer: C

Rationale: The correct answer is C: initial. In the sentence, "initially" should be used instead of "initial" to modify the verb "received." "Initially" is an adverb that describes the timing of the action, while "initial" is an adjective that describes a noun. Therefore, the correct usage is "He received an oral dose initially, followed by an IV drip." The other choices (A, B, D) are used correctly in the sentence and do not contribute to the error.

Correct Answer: B

Rationale: The correct answer is B: to roll. In this sentence, the verb "started" requires the infinitive form of the verb that follows. "To roll" is the infinitive form that correctly completes the sentence grammatically. A: "roll" is incorrect because it is the base form of the verb and does not match the structure needed after "started." C: "rolled" is incorrect because it is the past tense form of the verb and does not match the tense of the main verb "started." D: "will roll" is incorrect because it indicates future tense, which is not needed in this context.
