Grammar for HESI A2

Correct Answer: D

Rationale: The correct answer is D: broken. In this sentence, the verb "have" is paired with the past participle "broken" to form the present perfect tense. This tense is used to indicate that an action started in the past and is relevant to the present. The sentence structure is "subject + have/has + past participle." The other choices are incorrect because they do not form the correct verb tense for the sentence. A (broke) is the simple past tense, B (break) is the base form, and C (breaking) is the present participle. Therefore, the correct answer is D (broken) as it correctly forms the present perfect tense in the sentence.

Correct Answer: A

Rationale: The correct answer is A: work. In this sentence, the use of present simple tense "work" is appropriate as it indicates a general truth or habitual action. The other options are not suitable because B: are working indicates a current ongoing action, C: had worked is past perfect tense which is not needed here, and D: working is a present participle that doesn't fit the context of the sentence. Therefore, A: work is the best choice for this sentence.

Correct Answer: C

Rationale: The correct answer is C: otherwise. In the context of the sentence, "otherwise" is the most appropriate choice as it indicates that despite the patients resting comfortably, bed checks should still be done every half hour to ensure their well-being. "Despite" (A) is not the best fit as it implies a contrast rather than a necessary action. "However" (B) introduces a contrast rather than a condition. "Afterward" (D) indicates a sequence of events rather than a condition that should be met concurrently.

Correct Answer: A

Rationale: The correct answer is A: operate. In this sentence, "Two students operate the machine" is the correct form because it matches the subject-verb agreement in present tense. The other choices are incorrect because B: operating is a present participle and does not match the subject-verb agreement, C: were operating is past continuous tense which is not needed here, and D: has been operating is present perfect continuous tense which is also not appropriate for this sentence. Therefore, the correct choice is A: operate.

Correct Answer: A

Rationale: The correct answer is A. "Having completed" is a present perfect participle phrase that should be followed by a subject and verb, but in this sentence, it is not. The correct structure would be "Having completed the coursework that was required, Jorge is now preparing for exam week." B: "was required" is used correctly as the past tense of require in the passive voice. C: "now prepares" is used correctly as a present tense verb phrase. D: "prepared for" is used correctly as a past tense verb phrase.
