I am a new nurse and I just started my job as an RN. I have been with my preceptor a couple of times. He is very experienced, knowlegeable and fast, but i almost know nothing. He taught me things once and expected me to know next time, or otherwise he would stare at me and question me if i did sth wrong. I feel scared,dumb, and no confidence in front of him and i dare not ask any questions. I know i need to learn tons of stuff and i am a hard worker, but every time when i approach him to offer help or learn sth from him,he would say," i get my pts, and you go and take care of your pt". But i just have one pt, how can i learn everything from that one pt? I just do not know what i can do. Should i talk to my supervisor to swich to another preceptor, or Is he right? I need some suggestions. Thanks a lot!
