It's normal. I remember when I started my MED-SURG clinical (about a month ago). I said sorry more than any other word. You can be nervous, holding yourself to a high standard, or a number of other things. The factor that is the difference maker is if you care a bout being a nurse. If you do what you are supposed to, ask questions to the appropriate people, and try, YOU WILL BE A GOOD NURSE. Smiling always makes the day better!
