A nurse is caring for a client who has end-stage lung cancer. The client has a decreased level of consciousness, extreme shortness of breath, and a respiratory rate of 40/min. The client's family member states to the nurse, "My sibling doesn't have any advance directives. Can they still receive palliative sedation?" Which of the following statements should the nurse include when speaking with the client's family?

Choice A rationale Ethical medical practice always prioritizes the wishes of the client, even if those wishes were expressed previously or are currently being voiced by a surrogate. Stating that the client's wish is not followed is incorrect and violates the principles of autonomy and patient centered care. Palliative sedation is intended to provide comfort at the end of life, and the decision making process must involve the client or their designated legal representative to ensure ethical compliance. Choice B rationale When a client lacks an advance directive and has a decreased level of consciousness, medical decisions fall to a legal proxy or next of kin. This individual acts as a surrogate to make decisions based on what the client would have wanted, known as substituted judgment. Palliative sedation is a comfort measure for refractory symptoms like extreme dyspnea. Obtaining consent from a legal proxy allows the medical team to proceed with treatments that alleviate suffering while respecting legal requirements. Choice C rationale It is incorrect to claim that consent must have been obtained before a change in consciousness occurred. While proactive planning via advance directives is ideal, the healthcare system has mechanisms in place to handle situations where a client becomes incapacitated. If no prior directive exists, the legal proxy or surrogate is empowered to provide informed consent for treatments. Denying palliative care based solely on the absence of a prior written document would lead to unnecessary and unethical suffering. Choice D rationale Informed consent is a fundamental requirement for palliative sedation because the treatment involves the administration of medications that significantly alter consciousness. Even in terminal cases where the goal is comfort, the nurse and physician must ensure that the family or legal proxy understands the nature, purpose, and potential outcomes of the sedation. Administering such a potent intervention without any form of legal or surrogate consent would be a violation of medical ethics and professional nursing standards.
