A nurse is providing teaching for a client about advance directives. Which of the following client statements indicates an understanding of the teaching?

Rationale: A. This option is incorrect because choosing a health care proxy (also called a durable power of attorney for health care) is optional. Clients may choose to designate someone to make decisions on their behalf, but it is not required for all advance directives. B. This option is incorrect because a living will is a written document that outlines the client’s wishes for end-of-life care and does not delegate decision-making to a family member or friend. A health care proxy, not the living will itself, allows another person to make decisions if the client becomes unable to do so. C. This option is incorrect because advance directives, including a living will, can be changed or revoked at any time while the client is competent. Clients have the right to update their directives to reflect changes in preferences or health status. D. This option is correct because a health care proxy is an individual designated by the client to make healthcare decisions on their behalf if the client becomes unable to communicate or make decisions. This demonstrates understanding that the proxy acts according to the client’s wishes and best interests when the client cannot speak for themselves.
