I'm 52yo. LPN. 18 yrs in pedies, 2 yrs in ER. 5 yrs off due to re-marriage, re-locating, (etc , aka re-finding myself). --husb thought I would be ok w/ not working. I terribly miss the ER, and where I am now, I need my RN to work anywhere in the hospital. so...how old is too old to go for my RN? wondering about retirement age for nurses and simply would appreciate any advice.
