If they are crazy its not from interacting with the clients. Charting that much could drive anyone crazy, it seems like 99% of the time they are charting. So they're either predisposed and the charting pushed them over the top, or they were crazy in the first place for choosing a path with all that charting. In my psych rotation I don't believe I saw a nurse have 5 uninterrupted minutes with a client. The usual interaction consisted of clients shuffling up to the nurses station, nurse asking what they wanted, giving them a snack or meds and then going back to charting. I think the time a client was restrained was the longest patient/nurse interaction I ever saw. I guess they did follow clients to the gym, but still, what were they charting about for 12 hours, the gym? Or "Pt denies SI/HI" because they're back on their meds and have more food than meth in their system. That job quickly went in the same category as records review, on my list of things to do for food if I'm starving and living with my inlaws.
