What type of document should Mr. Burns have to ensure his wishes regarding medical intervention are followed?

A Living Will is a specific type of advance directive that outlines an individual's wishes regarding medical treatment in situations where they may not be able to communicate their preferences due to illness or incapacity. This document is particularly focused on decisions relating to life-sustaining treatments, such as resuscitation efforts and other critical care measures, thereby ensuring that health care providers follow the person's desires in accordance with their values and beliefs regarding end-of-life care.

While a Power of Attorney pertains to appointing someone to make decisions on an individual's behalf, and a Health Proxy designates a person to advocate for one's medical preferences, these do not specifically articulate the individual’s wishes about medical interventions themselves. An Advance Directive is a broader term that encompasses both Living Wills and Health Care Proxies, but if Mr. Burns' primary goal is to ensure that his specific wishes regarding medical interventions are recorded and clearly understood, the Living Will is the most suitable choice. It serves to communicate his preferences directly regarding medical treatment, making it crucial for ensuring that his wishes are respected in critical situations.
