Well, I'm not a psych nurse, but on the other side of the coin, I can tell you, I have been admitted into a psych ward on 3 occasions (severe suicidal depression). Some nurses talked to me more than others. Some breezed in and out with meds. As someone mentioned above, there was a bit of time before my meds kicked in where staff was a bit more "stern" with me, but I needed it, and actually appreciated it (I was not involuntarily committed, I came in because I recognized I needed help, for the sake of my children if nothing else).
On the other hand, having been on a surgical ward this past year after a hysterectomy, I found that there too, some nurses spend a bit more time with me, some breezed in and out to deliver meds, with nary a peek at my incision or asking about my pain or telling me I needed to ambulate more, etc. I think it is the individual nurse, not the specialty. But that's my personal opinion.
Myself, I'm a talker. Makes homehealth a challenge, as I end up in patient homes forever and a day. I got a lot of depressed pateints, as my specialty is OB (think postpartum depression). I can smell depression, it seems. While psych is not my specialty, I can do a lot of med teaching, etc as I certainly have the knowledge, but I always get the pysch CNS in there, as she is trained to be therapeutic, while I am more empathetic. Ya know?
Good luck in whatever you do.
