Final answer:
A health care proxy is a legal document that designates an individual to make medical decisions on behalf of the patient if they become unable to communicate their wishes. It is associated with a living will that may specify certain medical treatments to be used or avoided, affirming the person's healthcare preferences.
Step-by-step explanation:
The type of advance directive in which a patient appoints someone else to make medical decisions on their behalf should they become incapacitated is known as a health care proxy. It is a legal document by which the appointed individual, known as a proxy or agent, is authorized to make healthcare decisions if the person who appointed them is unable to communicate their wishes regarding medical treatment.
A health care proxy is often included in a broader document known as a living will, which may outline specific medical interventions the person desires or does not desire, such as life-extending treatments or a Do Not Resuscitate (DNR) order. This allows a person to be in control of their health care decisions in advance and to indicate their preferences concerning the treatments they want to receive, or not receive, in case they are terminally ill or in a condition where they can no longer express their wishes.
These legal documents reflect a person's healthcare preferences and values, and may be influenced by religious, cultural, or personal beliefs. It is important for individuals to discuss these wishes with their family, healthcare provider, and any appointed health care proxy to ensure that their choices are understood and can be acted upon when necessary.
