HESI A2 Grammar Practice Exam

Correct Answer: A

Rationale: The correct answer is A: stealthy. In the sentence, "stealthily" should be used instead of "stealthily" to modify the verb "moving." Stealthily is an adverb that describes the action of moving in a sneaky or secretive manner. The adverb form is needed to modify the verb “moving” in this sentence. The other choices (B: sneaky, C: reached, D: topmost) are all used correctly in the sentence. "Sneaky" appropriately describes the boy's behavior, "reached" is the correct past tense of the verb "reach," and "topmost" correctly indicates the position of the shelf.

Correct Answer: D

Rationale: The correct answer is D: their. In the sentence, "the nurses' laughter" indicates possession by a plural noun "nurses." Therefore, the possessive pronoun "their" is the most appropriate choice to indicate that the laughter belongs to the nurses collectively. The other choices (A: his, B: hers, C: them) are incorrect because they do not match the plural possessive noun "nurses" in the sentence. "His" and "hers" are singular possessive pronouns, while "them" is a plural objective pronoun.

Correct Answer: A

Rationale: The correct answer is A: principle. In the sentence, the word should be "principal" to refer to the main or leading role. "Principle" refers to a fundamental truth or belief. The other choices, B: role, C: provision, and D: convenient are all spelled correctly and fit appropriately in the sentence 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: B

Rationale: The correct answer is B: "whose." In the sentence, "whose" is used incorrectly because it is a possessive pronoun indicating ownership, but in this context, it should be "where." The doctor's diploma is not owned by the doctor, but it is located on the partition. The word "where" should be used to show the location of the diploma. A: "That" is used correctly as a demonstrative pronoun referring to the doctor. C: "Hung" is used correctly as the past tense of "hang" to describe the action of placing the diploma on the partition. D: "Partition" is used correctly to refer to the divider where the diploma is hung.
