A hospice patient has a legally valid advance directive that explicitly refuses artificial nutrition and hydration. The patient can no longer swallow, and their family, who is the healthcare proxy, is now demanding the insertion of a feeding tube, stating, 'We've changed our minds.' What is the CHPN's primary ethical and legal responsibility in this situation?
-
A
Follow the family's wishes as the healthcare proxy to avoid conflict.
-
B
Inform the family that the hospice must discharge the patient if they insist on the feeding tube.
-
C
Advocate for the patient's wishes as stated in the advance directive and initiate an ethics consultation.
-
D
Proceed with the feeding tube insertion as the proxy's decision overrides the advance directive.
