Don't know about the course, but I sure think it's a very needed requirement! I worked with a nurse who had been out of nursing for 17 years....selling insurance. She came back w/o attending any refresher courses...OMG

This woman was a time-bomb. She had lost all of her skills and wasn't 'up' with any information. She worked at our facility (the administrator wanted to give her a chance...plus was desperate for an evening nurse). She lasted about 3 months before she almost killed a patient. She had 4 liable suits against her when she left.
I think you'll enjoy the refresher. The value will be appreciated.
Good luck to you and welcome back!
