This is a hypothetical situation and wondering if anyone has experience in it. It's a thought I've had before. Scenario: The trained RN is in public and not on duty. He or She witnesses a man collapse and determines he is in cardiac arrest. The RN starts CPR. A family member directs the RN to with-hold CPR, stating that the man has a DNR/POLST stating no CPR. However, the order is not present. What do you do? What are potential repercussions? Do any laws protect the professional here?
