Grammar for HESI A2

Correct Answer: C

Rationale: The correct answer is C: effect. In the sentence, "affect" should be followed by "effect" as they form the cause-and-effect relationship. The correct usage is "Her mentor's advice was bound to affect her final decision." The word "effect" is a noun, while "affect" is a verb, so they complement each other in this context. The other choices, mentor's, advice, and decision, are all used correctly in the sentence and do not contribute to the grammatical error.

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: B

Rationale: The correct answer is B: envelope. In the sentence, the word "envelope" is used incorrectly as it does not fit the context of the sentence. The sentence is asking for a folder to be given to the person who replies to the page, not an envelope. The other choices (A, C, D) are used correctly in the sentence and are essential to convey the intended meaning. "Give" is the verb indicating the action, "whoever" is the pronoun referring to an unspecified person, and "replies" is the verb indicating the action that the person needs to do to receive the folder.

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: C

Rationale: The correct answer is C. The word "complements" is spelled incorrectly as "compliments." The verb "complement" means to enhance or complete something, which is the intended meaning in this sentence. The word "compliments" is a noun and refers to expressions of praise or admiration. The incorrect spelling changes the meaning of the sentence. A, B, and D are spelled correctly and are contextually appropriate in the sentence.
