Hello, I am new to this community and it looks like a great resource! I have just been hired at to work as a nurse extern in the Vanderbilt Medical ICU and it occurred to me that I don't really know what a nurse extern does! I will be working as an extern until I graduate. I have just finished my 1st year in the nursing program, and have 3 more semesters until graduation. Any information you may have, or experience as a nurse extern would be great!
