Everything takes time to get used to. I'm not a nurse yet, but I think that it is okay to be lost. You just got to get in the hang of things. Every new jobs' first day feel like you are lost. But, then you get the hang of it. It can but tough knowing that you are in charge of someone's life, you just need to ask other nurses and make sure you are safe and get that thang done! It just all takes getting used to.
