What is the main function of a health care proxy?

The main function of a health care proxy is to authorize another person to make medical decisions on an individual's behalf. This legal document allows the designated person, often referred to as a health care agent or surrogate, to make medical choices when the individual is unable to communicate their own wishes due to illness or incapacity. This ensures that the person's preferences regarding medical treatment are honored, even if they cannot articulate them at a critical moment.

Having a health care proxy is essential for effective health care planning because it allows individuals to have control over their medical decisions, even when they are not in a position to express them. This empowers patients and respects their autonomy, ensuring that their health care aligns with their personal values and desires.

While other options may touch upon relevant aspects of health care management, none fulfill the primary purpose of a health care proxy, which specifically focuses on decision-making authority in medical contexts.
