HESI A2 Vocabulary Quizlet

Correct Answer: A

Rationale: The correct answer is A: Complication. A complication is an undesired problem that arises as a result of another event. It is something that adds difficulty or complexity to a situation. In contrast, B: Complement means something that completes or goes well with something else. C: Procedures refer to a series of steps or actions to achieve a specific goal, not necessarily an undesired problem. D: Implemented means put into effect, which is not directly related to an undesired problem resulting from another event.

Correct Answer: A

Rationale: The correct answer is A: "Is." In the sentence, "Economics" is a singular subject, so it should be followed by the singular verb "is." "Been" (B) is past tense and doesn't match the present tense in the sentence. "Am" (C) is first-person singular, not third-person singular like the subject "Economics." "Are" (D) is plural, which doesn't agree with the singular subject. Therefore, "is" is the correct verb choice to maintain subject-verb agreement.

Correct Answer: A

Rationale: The correct answer is A: Were. In this sentence, the verb should be in the subjunctive mood to express a hypothetical situation. "Were" is the correct subjunctive form for the verb "to be" in the past tense when used in this context. It indicates an unreal or hypothetical situation. The other choices, B: Is, C: Be, and D: Was, are incorrect because they do not correctly represent the subjunctive mood required for hypothetical or unreal situations. "Is" is present tense, "Be" is an infinitive form, and "Was" is past tense but not the correct subjunctive form in this context.

Correct Answer: D

Rationale: The correct answer is D: Themselves. In the sentence, 'Most children must learn for themselves the importance of good manners,' 'themselves' is the reflexive pronoun that correctly refers back to the subject 'children.' 'Themself' (A) and 'theirself' (B) are non-standard forms and are not grammatically correct. 'Theirselves' (C) is also incorrect as 'theirs' is a possessive pronoun, not a reflexive pronoun. Therefore, D is the only grammatically correct option that maintains subject-verb agreement and properly refers back to the subject in the sentence.

Correct Answer: A

Rationale: The correct answer is A: Be observed. In the sentence, "be observed" is not correctly used because the verb "observe" should be in the passive form "observed" to match the tense of the sentence. The correct form should be "Confidentiality should be observed at all times." The other choices (B, C, D) are all used appropriately in the sentence and do not have any grammatical errors.
