Correct Answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

Correct Answer: B

Rationale: When addressing suspected abuse, it is crucial to ask direct questions to determine the cause of injuries. Choice B is the most appropriate as it directly inquires about the possibility of someone grabbing the client's arms, which could indicate abuse. This question can help uncover potential abuse and provide necessary intervention. Choices A, C, and D are less direct and may not elicit the critical information needed to address abuse effectively. Clients often hesitate to report abuse due to feelings of shame and fear of retaliation, making a direct approach essential in such situations.

Correct Answer: B

Rationale: A persistent cough might be related to an adverse reaction to captopril (Capoten). Tinnitus (choice A) and diarrhea (choice D) are not commonly associated adverse reactions of captopril. Muscle weakness (choice C) might occur initially but is not considered a common adverse effect of captopril. Therefore, the correct answer is B, persistent cough, as it is a known adverse reaction to captopril.

Correct Answer: B

Rationale: In performing a psychosocial assessment, the nurse follows a structured approach, starting with encouraging the client to describe problematic behaviors and situations. The next step is to elicit the client's thoughts about what has been described. This step helps gather more assessment data and understand how the client interprets the situation. Asking about feelings, exploring possible solutions, and understanding the client's intent in sharing the description are more complex processes that come later in the assessment. Therefore, the correct next step after describing behaviors and situations is to inquire about the client's thoughts.

Correct Answer: D

Rationale: The use of clichés in therapeutic communication is commonly construed by the client as the nurse's lack of understanding, involvement, and caring, which can lead the client to feel demeaned and discounted. Choice A is incorrect because clichés do not make the client view the nurse as less understanding but rather as lacking depth in communication. Choice B is incorrect as clichés do not directly lead the client to accepting themselves as human. Choice C is incorrect because clichés usually hinder self-disclosure rather than encourage it.
