Which type of directive is often used to outline preferences for medical treatment in case of incompetency?

A Living Will is specifically designed to outline an individual's preferences for medical treatment in situations where they may become incompetent or unable to communicate their wishes. This legal document typically specifies the types of medical interventions a person wants or does not want at the end of life or in the case of a terminal condition. By clearly stating these preferences, a Living Will serves as a guide for healthcare providers and loved ones, helping ensure that the individual's wishes are honored when they cannot speak for themselves.

In contrast, a Health Care Proxy forges another type of advance directive where an individual appoints a person to make healthcare decisions on their behalf, although it does not detail specific treatment preferences like a Living Will does. Similarly, a Medical Power of Attorney is about granting someone the authority to make medical decisions, which can include a variety of scenarios beyond just end-of-life preferences. The Out of Hospital DNR (Do Not Resuscitate) specifically addresses resuscitation efforts outside of a hospital setting and does not provide comprehensive treatment preferences for various medical situations. Each of these options has its specific purpose, but when it comes to explicitly outlining treatment preferences in the event of incompetency, a Living Will is the most appropriate choice.
