A nurse is caring for a client who wants to stop receiving treatment for terminal cancer. The client's family asks the nurse if it is possible to continue the treatment without the client's knowledge. Which of the following responses should the nurse make?

A. "Your family member has the right to refuse care." Every competent adult has the legal and ethical right to make decisions about their own medical treatment, including the right to refuse care, even if it results in death. B. "To continue treatment, you must be appointed as your family member's health care surrogate." The client is still competent and capable of making their own decisions, so a surrogate is not necessary or legally allowed to override their wishes. C. "We should discuss different treatment options when your family member is not present." Discussing medical decisions behind the client’s back would be unethical and violate the principle of autonomy. D. "I can submit your request to the ethics committee." There is no ethical dilemma here, as the client has the right to refuse treatment, and their decision must be respected.
