What statement by a client shows understanding of advance directives?

The statement that reflects an understanding of advance directives is one where the client acknowledges the importance of communicating their wishes about medical care to their family members. Discussing wishes ensures that the family is informed and can act in accordance with the client's preferences, particularly in situations where the client may be unable to voice their decisions later on. This proactive communication is a key component of advance directives, which are designed to guide healthcare decisions based on the individual’s values and desires when they cannot speak for themselves.

In contrast, the other statements indicate misunderstandings about the nature of advance directives. Relying solely on a doctor to make decisions does not ensure that the client's personal values and wishes will be honored. Assuming that family members inherently know what the client desires without any discussion can lead to confusion or conflict, as assumptions may differ greatly from the actual desires of the client. Additionally, delaying the completion of advance directive documents until a later age does not demonstrate an understanding of the importance of having those directives in place as soon as possible, particularly before a medical crisis arises.
