preceptor problems

I just started a new job recently. I worked for a year somewhere else. Before orientation I heard from a couple nurses in my unit that my preceptor was "difficult to work with". And now I'm finding out they weren't kidding. I expected to eat some humble pie just like I did starting my last job, but not to have deal with a personality problem. A month into the orientation and my preceptor still thinks I don't know how to make a bed or take a temp. Every time we go up to a new patient she spends 10 minutes complaining about how the last rn didn't do "x" right. Things that I did daily at my last job are difficult to accomplish b/c my preceptor is constantly hassling me. Since she has been a nurse for almost as long as I have been alive I feel like I should just nod and bite my lip. I don't think there are any bad intentions towards me but it still sucks. I spent a couple of days with different preceptors and they let me do way more- I learned more than I had in a month.

I thought about bringing this up with my manager but the unit is tiny and I don't want to raise a stink. I am a little concerned that a)I'm not learning enough, and b)I'm going to lose my temper at some point. Any advice is appreciated.
