A nurse is explaining advance care directives, or 'living wills,' to a client and the client's spouse. Which detail would the nurse include in the description of an advance care directive?

The correct answer is A because advance care directives, or 'living wills,' specify the client's preferences for medical treatment in case they become unable to communicate their wishes. This document outlines what treatments should be provided or withheld based on the client's expressed desires. This empowers the client to have control over their medical care even when they cannot actively participate in decision-making. Choices B, C, and D are incorrect because a living will does not require an attorney to be present when signing, an attorney does not necessarily draw up the papers, and a physician is not always required as a witness.
