During my last year in nursingschool I was attacked by an alcoholic.
Well up till there nobody knew he was, but as I entered his room for the last round on the late shift, he wasn't in his room. As I called him, he was in the bathroom, I thought his voice was a bit strange, but heh, so what?
Well that's the last thing I really know, till I came round in the ER with 5 stiches in my head!
Apparently the patient came out of the bathroom and hit me with a glass flowervase from behind.
He was admitted to the psych. ward immediately afterwards.
The best thing though: doctors and nurses on the psych. ward knew this guy from other "visits". (This was years before we used computers!) and knew he could be very aggressiv!
The doctor admitting him this time, didn't consult with a psychiatrist, because he thought it wasn't necessary!
(My attacker was admitted with a pancreatitis directly from his "livingroom" in the central station of Amsterdam and looked and smelled that way)
The good thing for me though, a week paid sick leave, that didn't have influence on my practical hours on this ward.
Since that time (and this happened 22 years ago) I am very careful when streetpeople are admitted!
