HESI A2 Grammar Practice Test 2024

Correct Answer: C

Rationale: The correct answer is C: bird. In the sentence 'The bird flew across the blue sky,' 'bird' is a noun because it is a person, place, thing, or idea. It is the subject of the sentence and represents a living creature. The other choices, A: across, B: flew, and D: blue, are not nouns. 'Across' and 'blue' are prepositions, and 'flew' is a verb. Nouns are essential in a sentence to provide the subject or object, while the other choices serve different grammatical functions.

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."

Correct Answer: A

Rationale: The correct answer is A: 'him or her.' In this sentence, 'child' is singular, so the pronoun must also be singular. 'Him or her' is a compound pronoun that covers both genders. 'Them' is plural and does not agree with the singular noun. 'It' is used for objects, not people. 'She or he' is not commonly used and sounds awkward in this context. Thus, 'him or her' is the only grammatically correct choice.

Correct Answer: D

Rationale: The correct answer is D: have to. In the sentence, the verb "try" should be followed by a base form of the verb, which is "have to" in this case. "Have to" indicates the necessity or obligation to try hard. A: "has to" is incorrect because it is present tense and does not match the tense of the sentence. B: "haven't" is incorrect because it does not fit the structure of the sentence. C: "had to" is incorrect as it indicates a past obligation, which is not suitable in this context. Therefore, D is the correct choice as it maintains the correct tense and meaning of the sentence.

Correct Answer: C

Rationale: The correct answer is C: bird. In the sentence 'The bird flew across the blue sky,' 'bird' is a noun because it is a person, place, thing, or idea. It is the subject of the sentence and represents a living creature. The other choices, A: across, B: flew, and D: blue, are not nouns. 'Across' and 'blue' are prepositions, and 'flew' is a verb. Nouns are essential in a sentence to provide the subject or object, while the other choices serve different grammatical functions.
