HESI A2 Grammar Practice Exam

Correct Answer: C

Rationale: The correct answer is C: understand. In the sentence, the verb "understand" should be followed by a direct object, such as "the essay." However, in this sentence, "the essay" is being used as the object of the preposition "to," making it incorrect. This error affects the sentence structure and clarity. A: pretends - Correctly used as the verb in the sentence. B: truly - Correctly used as an adverb modifying "understand." D: essay - Correctly used as the object of the preposition "to." Summary: "Understand" is the incorrect word as it does not have a direct object in the sentence, affecting the sentence structure and clarity. Other choices are used correctly in the sentence.

Correct Answer: D

Rationale: The correct answer is D: Although. This conjunction is used to introduce a contrast or concession. In this sentence, it sets up a contrast between the fact that the emergency room was not busy and the head nurse still not allowing anyone to end their shift early. It emphasizes the unexpected or contradictory nature of the situation. A: Because indicates causation, which does not fit the context of contrasting information in the sentence. B: Provided that suggests a condition for something to happen, but it does not convey the intended contrast in the sentence. C: As if is used to describe a hypothetical situation or comparison, which is not the case in the sentence. In summary, D is the correct answer because it effectively conveys the contrasting information in the sentence, while the other choices do not fit the context.

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: D

Rationale: The correct answer is D, "in the auditorium." This phrase is misplaced because it should come immediately after "presentation" for clarity. The sentence should read, "At a presentation in the auditorium, he informed us about the dangers of drugs and alcohol." The other choices are not misplaced as they are all positioned correctly in the sentence and contribute to the overall meaning.

Correct Answer: A

Rationale: The correct answer is A: spoke to the patient's parents. The sentence is in past tense ("had"), so the verb should also be in the past tense to maintain grammatical consistency. "Spoke" is the correct past tense form of the verb "speak." Choices B, C, and D are incorrect because they use present or future tenses, which do not match the past tense of the sentence. The verb should agree with the tense of the main verb in the sentence for grammatical correctness.
