Upon admitting a client to the hospital, the nurse receives an advance health care directive to include in the medical record. The directive is witnessed by two of the client's three children. How does the nurse interpret this information?
 
  1. This advance directive may not be legal as children cannot witness advance directives in some states.
  2. Having the children's signatures on the advance directive is good because it indicates they agree with the client's wishes.
  3. The advance directive cannot be honored unless it is witnessed by all three children.
  4. In order to be valid, the advance directive must be witnessed by the client's physician.
