In my 5 years as a Psych RN, most of my cutters/swallowers have been frequent fliers on 1:1 observation because of their danger to self behavior-swallowing non food objects and cutting themselves. Most of these patients have Borderline Personality Disorder, love to manipulate and be disruptive. I have had as many as three of these patients on the unit at once and they are exausting to care for. The last one body slammed a door and broke it in half.
