A nurse is caring for a young adult client who has major depressive disorder and has been found legally incompetent. The client requires informed consent for abdominal surgery. The nurse should recognize that which of the following people can consent to the surgery?

Introduction: Legal incompetence is a judicial determination that an individual lacks the cognitive capacity to manage their own affairs or make informed decisions. In such cases, the court appoints a substitute decision-maker to ensure the client’s medical and personal needs are met according to their best interests and legal protections. A. Because the client has been found "legally incompetent" by a court of law, they no longer possess the legal right to sign an informed consent document for a major medical procedure. Their signature would not be legally binding, as they are deemed unable to understand the risks and benefits. B. A psychiatrist is responsible for the client’s mental health treatment and can provide clinical recommendations, but they do not have the legal authority to provide informed consent for surgical procedures. The role of the physician is to obtain consent from the appropriate legal representative, not to give it. C. The client's appointed guardian is the only individual legally authorized to provide informed consent. Once a court removes a client’s competency, the guardian assumes the responsibility for making healthcare decisions. The nurse must verify that the guardian has been briefed by the surgeon and has signed the consent form. D. A friend, regardless of how frequently they visit or how close they are to the client, has no legal standing to provide informed consent unless they have been specifically designated as a healthcare proxy or durable power of attorney prior to the client's loss of competency.
