Yesterday I had a new admit with new onset of mental status change. The first thing the pt did after arriving to the nursing unit from emergency room - he had a bowel movement. Then I reviewed doctor's orders, enema was ordered. I called doctor and informed him that the pt already had BM. Doctor said that the pt still needs enema because CT of abdomen showed stool in colon. I read CT report. Nothing was mentioned about stool in colon in radiology report. If not mentioned I assumed that colon was WNL, why to give enema? But doctor still thought that enema needed. I told the confused pt about doctor's order, to my relief, pt refused, stating that he just had BM. Yes, sometimes confused patients can be smarter that doctors.
