What is nursing like?

I know its a really obscure question but what actually goes on because the only time I have been to a hospital I have only been near the auxiliary staff that go into bays to check BP and ask people if they want tea and coffee. Obviously I have seen other nurses go into bays in the ward. But everything i can think of to do with nursing is what i assume auxiliary staff would do and as i want to be a nurse I would like what a day would be like. I know this is for students but if you have been on placements will you tell me what it was like?
