I am a nurse, and I am SO SORRY to hear that so many of you have had bad experiences with nurses. That is unprofessional and absolutely inexcusable. I always try to go out of my way to be kind and caring to not only my patient, but to whoever came in with them. Being sick and in a strange situation is scary enough without being treated meanly or in a condescending manner. It doesn't take a lot of effort or time to be gentle or go the extra mile to make sure your patient is feeling safe, well informed and comfortable as possible.
A suggestion - if you're ever in that situation again, please report that nurse to her manager. I've worked both on the floor and as a Nurse Manager; as a manger or supervisor I would certainly want to know if someone was mistreating my patients; that nurse would not be working for me for very long. The nurse managers I know take this kind of complaint very seriously.
Again, sorry for your experience. Not all nurses are like this - you just happened to come up against some of the not so nice ones that don't belong in this wonderful profession.
