The main idea is that advance directives and living wills are both about guiding care when you can’t speak for yourself, but they serve different roles. An advance directive is a broad document that records your treatment preferences and also appoints a healthcare proxy or surrogate to make decisions on your behalf when you lack capacity. A living will is a more specific instruction about which life-sustaining treatments should be used or withheld in particular situations, such as terminal illness or permanent unconsciousness. When decisions need to be made, surrogates step in to apply the patient’s wishes, especially if there is no directive or the situation isn’t covered by the living will.

This option correctly captures both elements: the advance directive sets overall treatment goals and designates who will decide, while the living will details which life-sustaining treatments to use or withhold. It also notes that surrogates come into play when decisions are needed. The other descriptions are narrower or inaccurate: one portrays a living will as appointing a proxy, which it does not inherently do; another narrows an advance directive to life-sustaining treatments only; and a statement that a living will substitutes the patient’s own judgment for all decisions isn’t accurate, since the purpose is to reflect the patient’s preferences, often through a surrogate when the patient can’t decide.
