Well, we are all required to take PALS. There are also the monthly classes. Then there are various classes that nurses on our floor are required to take during our initial orientation.
Otherwise, I guess we mostly rely on what we learned in nursing school, about pediatric nursing. And, we rely on the more experienced nurses who have been taking care of these children for a while, to help us. We would probably have more intense training I suppose, if we took care of sicker patients on my floor. I myself WOULD like to have a bit more intense training. However, I feel like the best way to get that would be to go work at the children's hospital.
I hope I've been SOME help. Probably not much.
