Who can serve as an agent for an advanced directive?

The correct choice emphasizes that an agent for an advanced directive is someone who has explicitly agreed to serve in that capacity and has signed the document. This is foundational to ensuring that the individual appointed has the authority to make healthcare decisions on behalf of the person who created the advanced directive.

Having a designated person who is in agreement and formally willing to act not only reflects the intentions of the individual creating the directive but also provides clarity and accountability in decision-making during crucial health-related circumstances. It ensures that the agent is someone who understands the individual's values, preferences, and wishes regarding healthcare, promoting effective advocacy on their behalf.

While a family member could potentially be chosen, not all family members may have the understanding or willingness to act as an agent, making the explicit agreement vital. Similarly, healthcare providers typically represent the medical perspective, not personal wishes, unless specified as the agent. A person with power of attorney may have the authority over a broader range of decisions, but without the clear acknowledgment and specific agreement to handle health care decisions, they may not fit the role defined by an advanced directive.
