i finished school not to long ago and i had the same questions you do! my preceptor was amazing! i'm not sure if you can request a certain nurse or not... we were given the opportunity to request a nurse as long as we were not related. i re-learned so much that i was "taught" but never really understood (come to find out) and was told things that i know i was not told in class! if you feel as though your nurse does things just to "get by" and finish her day i would request a new preceptor! along with the everyday hustle and bustle of being a nurse set one more goal for yourself... learn something new about each patient you have every shift (not about the patients life necessarily but more so their disease process)! when my preceptor told me that this is her goal for each one of her students (along with not killing the patients) i thought she was nuts! holy cow... she wasn't kidding! i left every shift knowing at least one new thing about each patient's disease process!! i was one tired cookie at the end of the day but it turned out to be awesome! after the first few shifts i realized i was not retaining as much "new" stuff that i was learning as i would have liked; so, after every shift i went home and made myself type up or write out what i had learned that day and how my day went. i flagged, with a post-it, the disease process so i could find it later if need be. i have to say, i've got most of it down like the back of my hand but every once in a while i look back at my notes and it really helps! be confident in what you know and very open to learning a new way of doing things!!! keep in mind that the "real" way of doing things is not the nclex way of doing things.... keep them separated in your mind for just a little bit longer and you will do fine! good luck and most of all learn alot!!!!!!!!
