mosschops, to be brutally honest, dont expect to be welcomed with open arms as a student
in the wards these days staff are stretched to the max, and they will just see you as something else they have to squeeze into the shift
NOT THAT THEY DONT WANT YOU THERE!
its just they worry they wont be able to fulfill what you need them to, that they wont be able to spend enough time with you also
(and i whisper, a lot of student these days stand around with their hands in their pockets, waiting to be told what to do, watching the clock for hometime, although im sure thats not you!)
if you work hard and pay attention and use your initiative (a nurses best asset is to use her initiative i personally think) then even after 2 or 3 shifts your mentor will find you likable and you can get to know each other
if you see things that need done offer to do them
ask your mentor friendly questions at breaktime (if you ever get one!)
and dont take snappy comments or questions to heart
tons and tons of luck
where is the placement btw?
