What is the role of a health care agent?

• A. To make medical decisions for the patient as specified in a power of attorney for health care
• B. To manage hospital billing
• C. To determine the patient's religious preference
• D. To supervise the medical team

Answer: (A)

A health care agent acts as the patient’s substitute decision-maker for medical care when the patient cannot participate in decisions themselves. This role comes from a power of attorney for health care, which names the designated agent and outlines when and how they should decide. The agent’s authority kicks in once capacity is lacking, and their decisions should reflect the patient’s known wishes, values, and any advance directives the patient laid out. They may discuss options with clinicians and family, but the guiding principle is to honor what the patient would have wanted, not to pursue unrelated tasks. This role is not about handling hospital billing, determining religious preferences unless those preferences were explicitly documented for decision-making, or supervising the medical team—that supervision and administrative duties lie elsewhere. The essential idea is that the health care agent makes medical choices on the patient’s behalf, in line with the documented directives.
