First, let me welcome you to Allnurses.com.
Second, many states are now moving towards a five year cut-off.
Things have changed so much since you actually worked as a nurse.
Few examples: computerized charting, laparoscopic surgery, minimally invasive heart surgery where the patients are recovered similar to a patient who has had lung surgery, stereotactic brain surgery, Gamma Knife procedures, just to name a few.
More than likely, I would suspect that any state will make you take your boards again. And this is new also. Standardized exam that is good for the entire US and done on computer.
