An Advance Directive can also be called which of the following?

An Advance Directive is a legal document that outlines a person's preferences regarding medical treatment and end-of-life care in scenarios where they may no longer be able to communicate their wishes. A Living Will is a specific type of Advance Directive that explicitly states an individual’s desires concerning medical interventions and life-sustaining treatments in the event they become incapacitated.

By clearly indicating their treatment preferences in a Living Will, individuals ensure that their wishes are respected by healthcare providers and family members, providing clarity during difficult times. This connection between Advance Directives and Living Wills highlights the critical role that Living Wills play in the broader category of Advance Directives, making it the correct answer to the question.

Other choices, such as a Standing Order, Treatment Order, or Power of Attorney, represent different concepts in healthcare decision-making. A Standing Order refers to a protocol that allows specific actions to be taken without direct physician orders, a Treatment Order is a directive for medical treatment given by a healthcare provider, and a Power of Attorney designates a person to make legal decisions on behalf of another but does not specifically address health care preferences.
