For a stethoscope, the Littmann Classic SE II is great for students. That's what I used throughout nursing school and then after I graduated I upgraded to the Littmann Cardiology III, but I still have my Classic II as a back-up. Works great. I personally wouldn't settle for anything less (like the Littmann Lightweight or the Littmann Classic) because the acoustics with the Classic II are better. I think it's also better to splurge on a nicer stethoscope instead of just settling for whatever is the cheapest. Chances are you'll be replacing that "cheap" stethoscope more than once.
If you decide to purchase a Littmann, get an ID tag or engrave it. And don't leave it lying around, they tend to "walk" away!
For nursing school supplies:
* bandage scissors
* lots of black clicky pens because you are only supposed to document in black pen and you do not have to worry about the caps
* storage clipboard...you can purchase them at Walmart for around $10. It's a clipboard that opens up so you can store papers and other things inside. Some have calculators on the them, too, which can be handy.
* RNotes pocket guide (I think it's around $25)
* Highlighters, folders, binders....I remember some of my classes issued a pre-bound book of notes while others issued notes that were loose, so they had to be placed in a folder or a binder.
Don't spend money on a blood pressure cuff unless your school requires it.
As for uniforms, usually they are offered through the school. We were required to wear these God-awful navy blue polos with a patch on the sleeve, but we were also allowed to wear scrub jackets. I bought the polos and our lab coat through the uniform company and I went to a scrub store to buy navy blue scrub pants and scrub jackets. I had two sets of uniforms, we only had clinical once/week.
