PICU externship

I just graduated and interviewed at our local PICU for an intern position. The initial HR one was pretty gross- just an HR person reading a list of questions off a list (typical stuff like give me 2 adjectives that describe yourself- OH PLEASE!) The one with the director was more detailed - asked me specifically about myself and the program I went through. Most of the questions were based on "behavioral interviewing". IE she asked me about certain scenarios and what would I do....kind of NCLEX like, with each answer, the scenario grew and intensified. For example, she asked me "If you were sitting in the main RN station and a woman carrying an infant car seat walked up and told you that her pediatrician told her to come and admit her child to the hospital, what would you do?" (by the way, our unit is on the 5th floor, and the ED is on the first, so it would be weird for a person to come all the way up the elevator....) See where I am going with this?! Think about clinical situations that you can use to describe events and how you handled them (a time you made a client feel really special/good, a time you failed at something, a time you didn't agree with a doctor's order). Have fun, and be yourself! My interview went great, and I got the job, had my first day yesterday!!!!! Good luck!

I just got an externship in the PICU and start at the end of the month. I am very excited and very nervous! Any advice?
