You have to actually get them to the bed and hold them in that position.
The issue is that these patients are very volatile. You can't anticipate a change in their behaviour. For example, a clerk went in to stock a room with a patient on meth who was being very co-operative. The next thing was that this patient was actually on the clerk choking him and staff are pulling them off. You can't anticipate the behaviour. That's part of it. It's very unpredictable.
