I've had a good preceptor, an ok preceptor, and a bad preceptor. All in 4 short months since graduating!
The good preceptor was open to questions, encouraged independence, shared her time organization tips with me and helped me to learn the policys and procedures required of my unit. She was helpful with charting, and searched out many learning opportunities for me while I was orienting.
THe ok preceptor was quite friendly with me, but was slow to let me do things on my own, and was kinda mean about my not knowing how to do things at times. But she would answer the questions I asked her, and helped me learn how to deal with some of the docs that were very picky.
The bad preceptor just leaves me on my own, isn't available when I ask questions, isn't helping me learn the way the unit works, and doesn't help me find learning opportunities. She assigns me pts and does not check to see that my work is ok, that the pt. is ok, etc. It really irks me, because even if I HAD messed up, I would never know from her.
I would DEFINATELY try to get a different preceptor if I were you. I have tried myself, but no one else on my unit has enough experience to orient me. I feel like having a bad preceptor is teaching me how to be a bad nurse. I don't see it as "at least you know what NOT to do", because that still leaves me not knowing what I should do. If the preceptor is that bad, for your sake and the sake of others behind you, let someone know!!!
Best of luck to you!
