How many nursing staff do you consider reasonable for x # of patients on psych units? I was offered a job in psych and the manager was so rushed that I didn't get to ask all my usual questions. Won't take the job without getting this clarified along with other issues, but wondering what others consider reasonable for a 12-hour night shift. I've been working as a med/surg RN and I worked as a MHC on a psych unit before nursing school. I had the impression that psych nurses typically don't feel as overworked as med/surg nurses, but that would depend partly on the staffing.
