When in doubt - just ask. If you're working with a great group of seasoned ER nurses, they'll help a newbie out! I went directly into the ER after graduating RN school and I absolutely love it! I work with a great group who have been (and continue to be) great mentors! There's ALWAYS going to be things you don't know how to deal with - that's why teamwork is of upmost importance! Each nurse has their own nitch and as you work with your group, you learn who is best to ask about each situation you're faced with. Do your best and show your co-workers that you are ready to learn and you'll do great! Good luck! :)
