Change Jobs?????????

I have been an LPN for 4 years in long term care. I have been at the same nursing home right out of school. I love the nursing hame and have had great opportunities. I started as a floor nurse for 1 year, MDS coordinator for 1 year now I am the Medicare case manager (also acting as medicaid nurse) for 2 years. This in most states is a job only given to RNs. I have gained great experience doing so but feel I am ready for change. I want to go to the hospital but I am scared to death that I have lost clinical experience already.............any advise??????????
