Dear David, I can appreciate your nervousness especially since this is your first job like you said, not just that you are now a CNA. I just recently finished a CNA course as well and start my clinicals Mon the 16th. Since this is your first job, then I am probably a little older than you and have experience in several different fields of work. This is my advice: (1) Carry a tablet and pen to make notes of anything of importance and the most important . . . (2). I can tell you as a person who is close to getting her bachelors in psychology / social work to Stop worrying", I say again, "Stop worrying" because if you are busy running around in your head thinking, "Ï'm going to miss something . . I'm going to miss something . . . ", sure enough you will miss something! Breathe deep, concentrate on what your mentor is explaining, take notes and think, "Ï can do this."
