Well, I have been doing rehab for a couple of years. It is a speciality. There are different kinds of rehab....there is orthopaedic, traumatic brain injury, spinal cord injury, neurological etc.
There are a wide range of patient ages, from the young to the old.
There is certification that you can get to become a certified rehabilitation registered nurse.
Patients are not in their room all day. They go to the gym for their exercises and they come back to their rooms. You work closely with the physical and occupational therapists.
Some people say that rehab is like working in a nursing home. Well, I work in acute rehab and it is far from a nursing home. We hang blood, administer IV's, etc.
Hope this is of help. Good luck
