Hey I know I am a little late on this reply, but I currently am a CNA at a Rehab Hospital, and I have to say I really like it. We have knee replacement pts, hip replacement patients, back surgery patients, CVA's, ect. They come in and usually stay on average anywhere from 2 weeks to a month and receive Speech therapy, occupational therapy, and physical therapy on average 3-5 hours a day. The great thing is you see get to see them leave doing so much better than when they came in. I am starting my nurse extern there and plan to work as a nurse there once I receive my license. The doctors and NP's are very nice and the nurses all seem to be in pretty good moods most of the time.
As far as nursing the only thing I ever hear the nurses complain about is my facility is on computer charting, but we still use paper MAR's and sometimes the nurse has to tract the patient down in the gym to do an accucheck or pass meds. But our facility isn't huge or anything so its not to bad. And we could use some more resources as well, but we do have a hoyer lifts and everything we need for transfers.
