Final answer:
Medical power of attorney is a legal document that appoints an individual to make health care decisions for someone who cannot make those decisions themselves, ensuring their autonomy and wishes are respected.
Step-by-step explanation:
The term medical power of attorney refers to a legal document that designates an individual to make health care decisions on behalf of another person who is unable to make decisions for themselves. This role becomes active when a person is incapacitated or incapable of communicating their health care preferences. It is a key element in ensuring the principle of autonomy is upheld, allowing the appointed person to make decisions that align with the incapacitated individual's wishes and best interests. Medical power of attorney is different from a living will, although a living will may include the appointment of a health care proxy. The health care proxy has the authority to make medical decisions for another individual, reflecting their desires regarding treatment preferences and end-of-life care.
