I have recently started in a Trauma1 ED and it is wild. There is an underlying order in the chaos. Hey, Dream'n, you are seeing the nursing from the patient's side of things, but I promise it isn't as hard as it looks. If it is something you still have an interest in, I would suggest that you see if you can follow a nurse for a shift and see how different it looks from the other side. Especially if you are already an experienced nurse, you just don't know until you try it!! There is such a different focus in emergency nursing, it is very cool, and very fast....no long drawn out assessments and documentation (yaaayyyy!!!). Until I tried it, I didn't know, and I would suggest that you don't either....until you really look....(IMHO).
It is like any other area in nursing, it takes months to be competent and years to reach mastery....but if you feel it is something you would enjoy...don't sell yourself short!! You can get there!!
