Final answer:
A notarized original of advance directives should be given priority for an unconscious client's care, including a living will, potential DNR Order, and health care proxy assignment.
Step-by-step explanation:
When an unconscious client enters the emergency department, the document given priority to guide the direction of care is a notarized original of advance directives brought in by a partner or family member. These directives may include a living will, which stipulates specific medical interventions a person does or does not want, such as life-extending treatments, and a Do Not Resuscitate (DNR) Order. The advance directives may also designate a health care proxy, empowering a chosen individual to make medical decisions on behalf of the incapacitated person in line with their expressed wishes.
