I experienced a similar thing with my preceptor, except I felt she was hard to read from day one. Well, I felt like I couldn't talk to her so, I went to my manager. She had both us us sit down and hash it out. Imagine my surprise when my manager told me my preceptor told her privately that I was doing really really well! It worked out this way, but I wish I had approached my preceptor first. I still have to ask her for feedback soemtimes, seems people forget how much we really may need, i have an especially hard time reading how I am doing. I go off precepting in a week, and I know I will miss my preceptor, it was the first new grad she has ever precepted so I know we both learned a lot from it (for instance, she worked for a week under the belief that I did not even have a nursing liscence-
that was so not fun.
Experienced nurses will (i hope) second me in the effort required to be a preceptor, especially of a new grad. Perhaps she is a little tired? Her exhaustion, however should not affect your experience! This is your time to get comfortable with the unit and your role as an RN. You have enough to worry about without feeling intimidated. If you can, ask your preceptor, if you are intimidated (as I was) ask your manager what can be done- a new preceptor may or may not be the answer. I wish you the best of luck, please let me know how it turns out
