A: The autonomy of the patient is paramount in medical ethics. If the client understands the risks and still refuses the procedure, their choice must be respected. It is a fundamental right for patients to make informed decisions about their own healthcare. B: While a durable power of attorney for health care is crucial when a patient is incapacitated, it does not override the wishes of a competent patient. As long as the client is capable of making decisions, their consent is required for any procedure. C: Although religious beliefs are respected, they do not serve as the primary deciding factor if the client is competent. The client's understanding and decision-making capacity are the key determinants in whether to proceed with the surgery. D: The ethics committee can provide guidance on complex cases, but it cannot make decisions for a competent patient. The committee's role is advisory, and the final decision rests with the patient.
