Lisa, I commend you for wanting to get prepared for nursing school
. I didn't prepare at all. I hadn't even been a CNA. The closest I came was working as a medical secretary in a doctor's office and then in a surgical pathology office.
Needless to say, I was a nervous wreck when it came to my first day of clinical. The thought of actually having to give someone a BED BATH was overwhelming!! My first clinical took place in a long term care facility. My very first patient was a lady with pathological fractures. The "regular" nurses on the floor were happy to have a student for this lady. Basically, they handed me a washcloth and towel and said...."have fun." The patient was "with it" and knew exactly what I was doing. I had her rolled over on her side to wash her back. It took me FOREVER!! Her face was in her pillow, and after some time I heard her say, "you're awfully slow, aren't you?" Well, I felt horrible (and I was pre-menstrual) so I finished her bath, made her comfortable and ran out of the room to cry!!! I will never forget that. Here it is 9 years later, and I'm very happy doing what I'm doing (in LTC!!!)
Remember that there is ALOT to learn. Just try to get through it one day at a time, one course at a time and one patient at a time. Don't let the "know-it-all" nurses get you down. There are good nurses out there who love to share their knowledge. Try to find one of those and you'll be fine.
Good luck and have fun!
