help with organizational skills

I am an RN in a busy family practice office. I am wondering if anyone can share tips/advice on staying organized. Here is a typical day.

I do triage nursing so I am answering the phone and scheduling appts, giving advice, sending people to the ER, etc. On top of that the Dr. comes out from exam room asking for various testing to be scheduled (CT, MRI's, etc). During my "down time" when the phone isn't ringing I am calling in Rxs, scheduling referral appts, doing Prior Auths, and helping the MA keep the exam rooms filled with patients. For example, if the MA has a blood draw and the doctor is in with a pt and doesn't have anyone to see, it is my responsibility to room the next pt. Meanwhile, the doctor is answering questions generated from phone calls and I am responsible for checking the urgent box and getting back to those pts who have called in. I am not complaining but I feel like I have ADD sometimes!!! Another nurse in the office seems to stay so organized and on top of everything and get work done so much faster!

Any advice would be appreciated
