A nurse is caring for a client who has inoperable kidney cancer. The client states, "I need to talk to my partner because they have to make decisions for me if I am unable." Which of the following actions should the nurse take?

A durable power of attorney for healthcare (DPOA-HC) is a legal document that designates a specific person (healthcare proxy or agent) to make medical decisions on behalf of the client when they are unable to do so. This is exactly what the client is describing. A DNR is a specific order, not a mechanism for decision-making authority. A living will expresses the client's own wishes — the partner cannot complete one on their behalf. A POLST is a provider-generated order form for clients with serious illness, not a proxy designation document.
