Well... I have been an RN for about a year and a half. After graduation I applied for a critical care fellowship. It has been great and has been a great benefit as a new grad. I do work open heart recovery, do IABP, and CRRT. I had extra training in these areas and was lucky to have had preceptors that were great and a unit director who believed in my abilities even as a new nurse. I guess the best part about where I am working is I know if I have a question someone is there to help me out. Not all nights are like this granted there have been nights where I was the most experienced ICU nurse on the unit. But my advice to you is if you feel ready to take this training then take it! After the classes you will know if you are ready for it! When you do have a CRRT or IABP on the unit, stop in ask questions like crazy!! Thats what I did. Everyone in my unit knew I was interested and loved explaining things to me. Well I hope you get into your classes!! Good Luck!
