HESI A2 Grammar Practice Test 2024

Correct Answer: D

Rationale: The correct answer is D: which. In this context, "which" is a relative pronoun that refers back to "French braid." It introduces a subordinate clause that provides additional information about the style of Tracey's hair. The use of "which" helps clarify the relationship between the main clause and the subordinate clause. A: "among" is a preposition and does not serve as a relative pronoun to connect the clauses. B: "it" is a personal pronoun and does not provide the necessary connection between the clauses. C: "that" is a demonstrative pronoun and lacks the specificity required to refer back to "French braid."

Correct Answer: A

Rationale: The correct answer is A: who. In the sentence, "Children who obey their parents tend to do better in school," the word "who" is a relative pronoun that introduces a clause describing the children who obey their parents. The relative pronoun "who" is used to refer to people. It connects the main clause to the subordinate clause in a grammatically correct way. Explanation for why other choices are incorrect: B: which - "Which" is used for things or animals, not people. C: should - "Should" is a modal verb indicating obligation or possibility, but it does not fit grammatically in this context. D: to - "To" is a preposition and does not serve the same function as a relative pronoun in connecting the clauses.

Correct Answer: B

Rationale: The correct answer is B: among. In the sentence, the word "among" should be replaced with "between" because "between" is used for comparing two things, while "among" is used for comparing more than two things. The sentence is comparing two treatment protocols, so "between" is the appropriate word. A: The word "real" is used correctly in the sentence to emphasize that there is no actual distinction between the treatment protocols. C: The word "protocols" is used correctly to refer to the specific sets of guidelines or rules for the treatments. D: The word "online" is used correctly to specify that the recommended treatment protocols are found on the internet.

Correct Answer: C

Rationale: The correct answer is C: receipt. In the given sentence, the word "receipt" is not used correctly because the cashier hands over the receipt after the transaction, not simultaneously with the change. The receipt is typically given last as proof of the transaction. A: "ringing" is used correctly as it refers to the action of totaling up the nails. B: "cashier" is used correctly as it identifies the person performing the transaction. D: "change" is used correctly as it refers to the money returned to the customer after payment.

Correct Answer: C

Rationale: The correct answer is C: patient. In the sentence "The nurse helped the patient with the medication," the verb "helped" is the action being done by the subject "nurse." The direct object is the recipient of the action, which is the patient receiving the help. Therefore, "patient" functions as the direct object. The other choices are incorrect because: A: helped - This is the verb of the sentence, not the direct object. B: nurse - This is the subject of the sentence, not the direct object. D: medication - This is the object of the preposition "with," not the direct object of the verb "helped."
