Which criterion should a nurse use to determine the proper length of the needle to administer a subcutaneous (subcut) medication?

Maintain trust and avoid behaviors that may increase agitation. This is because the client is likely experiencing a manic episode, which is characterized by increased activity, rapid speech, and decreased need for sleep. The nurse should use a calm and supportive approach, provide a safe and structured environment, and avoid confrontation or criticism.

Choice B is wrong because ordering the client to go to their room and alerting security would escalate the situation and violate the client’s rights.

Choice C is wrong because telling the client to sit down or risk isolation and loss of privileges would be threatening and punitive, which could increase the client’s agitation and anger.

Choice D is wrong because sedating the client after collecting a lithium level would be premature and inappropriate without a physician’s order and without assessing the client’s vital signs, mental status, and medication history. Lithium is a mood stabilizer that can cause toxicity if the level is too high.

“I can’t promise that the information won’t be shared if your health or safety is involved.” This response by the nurse would be appropriate because it respects the client’s confidentiality while also acknowledging its limits of it. The nurse has a duty to report any information that may indicate a risk of harm to the client or others.

Choice A is wrong because it dismisses the client’s need to share something and implies that the nurse is not interested or trustworthy.

Choice B is wrong because it gives a false assurance of confidentiality and may lead to ethical dilemmas if the client reveals something that requires reporting.

Choice C is wrong because it does not address the issue of confidentiality and may give the impression that the nurse is trying to avoid the conversation.
