Final answer:
An agent with power of attorney cannot allow treatments, like dialysis, that the patient's living will prohibit, as they must adhere to the written instructions regarding life-sustaining interventions.
Step-by-step explanation:
The agent with power of attorney rights is not permitted to allow dialysis when a living will prohibits it. A living will is a legal document that specifies the medical treatments one wishes to receive or not receive if they becomes unable to communicate their decisions.
This often includes instructions for life-sustaining treatments such as dialysis. The health care proxy, appointed by the living will, is obligated to follow these written instructions and cannot authorize treatments contrary to the patient’s expressed wishes. The agent can refuse life support if it is in line with the advanced directives, contact specialists for a second opinion, and can potentially spend the patient’s money to arrange for home health care if it respects the boundaries of their legal authority and the patient’s wishes.
