You didnt "forget" everything, you are simply new and not used to pressure. Your are going to have to figure out how to manage your anxiety as you cant always go to work doped up on benzos :) That being said take a deep breath remember your KITES, knock, introduce, tell them why you are here, eliminate germs (sanitize), check safety, nursing instructors want to know you can manage yourself, almost moreso than the pt. sometimes. Make sure you are asking questions during hand-off, start your assessment, remember what you are in the room to do. Get the vitals, then head to toe, address all safety issues, sanitize out. Assessment is the key. You have to be in charge and be confident. Always ask the pt. if there is anything you can do for them. Assessment is the key, write stuff down! You will be a great nurse even with GAD, it is all about management, get your routine and execute! Good Luck!
