Final answer:
The Durable Power of Attorney for Healthcare Decisions allows Bill to make healthcare decisions for Kathleen.
Step-by-step explanation:
The Durable Power of Attorney for Healthcare Decisions authorizes Kathleen's husband, Bill, to make healthcare decisions for Kathleen in the event she becomes mentally incompetent. This means that Bill will have the authority to make medical treatment decisions on Kathleen's behalf, such as choosing treatment options, consenting to surgeries, and deciding on end-of-life care. It does not grant Bill the power to make financial decisions, legal decisions, or educational decisions for Kathleen. The Durable Power of Attorney for Healthcare Decisions is specifically focused on healthcare matters.
