Which statement about advance directives indicates a client's understanding of the topic?

The statement indicating a client's understanding of advance directives is that a health care proxy will decide for them when they are unable. Advance directives are legal documents that allow individuals to outline their preferences for medical treatment and appoint someone to make decisions on their behalf in situations where they cannot communicate their wishes. This understanding reflects the key concept of a health care proxy, which is a critical component of advance directives, highlighting the importance of having a designated individual to advocate for the client's wishes if they become incapacitated.

In contrast, making one's own health care decisions is not applicable in scenarios where a person is unable to communicate, which is the primary purpose of advance directives. The notion that advance directives are not legally binding is incorrect; they are indeed legally enforceable documents designed to protect the individual's preferences. Lastly, while family members may play a role in decision-making, advance directives specifically aim to clarify that a designated health care proxy is responsible for these decisions, ensuring that the individual's choices are honored according to their wishes rather than relying solely on family opinion.
