It's intimidating at first because you are expected to know so much, but honestly it all comes down to your preceptor. Unfortunately the preceptor can make or break your first experience in the hospital. I loved mine and learned so much from them. Within 3 months I felt really comfortable. Just keep reminding yourself that you're still learning and that there are people there to ask questions of. You don't have to know it ALL yet! :-) Be confident! Good luck!
