I've been a med/surg nurse for 12 years. I did tried icu -gave it a year and hated it. Not sure if it was actually the icu or if it was the facility. I went to another hospital. I've always liked er, but not sure I would be any good. I'm 49 years old now, not sure if u can teach a old dog new tricks. I'm so task oriented from doing med surg for so long. I'm scared if I switch, I will hate it. Any advice on what makes a good er nurse?
