What document authorizes a client to name someone else to make medical decisions on their behalf?

The durable power of attorney for health care is a legal document specifically designed to allow an individual to designate another person to make medical decisions on their behalf in the event that they become unable to do so themselves. This document ensures that the individual’s healthcare preferences are honored when they cannot communicate their wishes. It provides clarity and authority to the appointed person, allowing them to act in the best interest of the client concerning medical treatment and decisions.

The other options, while related to healthcare and decision-making, do not specifically grant the right to appoint someone else for such responsibilities in a comprehensive manner. An advance directive generally encompasses a range of instructions regarding medical treatment preferences and can include components like a living will, but it does not by itself designate an individual to make decisions. A living will primarily outlines specific medical wishes regarding life-sustaining treatment without naming a decision-maker. Client rights proxy is not a recognized term in legal documents related to health care decision-making. Hence, the durable power of attorney for health care is the correct answer as it uniquely fulfills the requirement of appointing a representative for medical decisions.
