Review Question - QID 214714

A critically ill 88-year-old man who has been admitted to the intensive care unit for 2 weeks with end-stage cancer undergoes a full resuscitation effort after a cardiac arrest occurring overnight. After the event, the patient's family is angry, stating that the patient did not want to be resuscitated and had signed Do Not Resuscitate (DNR) orders the morning before the event. Later, it is revealed that the resident who had gone over the DNR paperwork placed the paperwork in the chart but did not otherwise document the orders or inform the night resident. Which is the best way to prevent a similar future error?
