Did you not have any clinical rotation through the ER in nursing school
? I'd write a letter and complain to your nursing school if not. Of course, I'm biased and think nursing schools
need to put students in the ER far more than they do in order to learn essential skills, especially IV starts. /soapbox
As far as your concerns, even experienced nurses get behind on charting. Sometimes you get slammed with three patients inside of fifteen minutes. It happens. You can always go back and chart something, just remember to write down what you did and what time you did it. As someone mentioned, ER charting is usually focused on fast charting, not the sometimes monotonous charting you'll find on floors.
If you aren't able to handle upset family members, angry people, etc., definitely find another job, lol. You have to have very thick skin to be an ER nurse. If you don't have it, grow it. You'll have patients crying, screaming, cussing, and so on. I had a patient the other day whose husband despised nurses because he had a PCN reaction in the 60's and "almost died." So, he was cussing me the whole time I was starting an IV on his wife. People are idiots. People are overly dramatic in the ER. You can't let it affect you either way or you'll never be able to do your job.
