I work in the ER and I do many different things.
Fiberglass splints, wound care, wound dressings, set the doctors up with suture kits, assist doctors with pelvic exams, collect specimens and take them to lab, take patients to xray, ct, ultrasound, assist the nurses in whatever they need, take vital signs, register patients when they come in thru triage and be an all around gopher.
I used to work on Medical and although ER kills me sometimes and can be very stressful, I throughly enjoy it and would like to continue working there when I become an RN.
On medical my general task would include bathing and toileting patients, feeding the ones who needed help, transporting them to procedures, changing linens, taking vitals and assisting the nurses. I liked what I did don't get me wrong, I just prefer the fast turn over that the ER has.
