Here's mine: This PCA who constantly slacks, doesn't report pertinent info, etc left a foley bag unclamped after he drained it. He had tucked the end into the holder, just left it unclamped. Flooding the room with urine! I walked into the room and was standing in a lake of urine. Got everything mopped up, Cavi wiped my shoes, come in the next day to see the patient on contact for...wait for it...VRE in the urine. Ugh.
