A nurse is caring for a client who has a living will on file stating no feeding tube insertion. The client's durable power of attorney for health care, their sibling, requests a feeding tube to prolong life, refusing to honor the living will. What is the nurse's best action?

Proceed with inserting the feeding tube since the proxy's decision overrides the living will.

Ignore both the living will and proxy and provide comfort care only.

Consult the hospital ethics committee before taking any action regarding feeding tube insertion,

Inform the health care provider of the conflict and advocate for honoring the client's living will
