Transitioning to nursing

A year and 3 months ago I graduated from a radiologic technology program and am now a Registered Radiologic Technologist. Since graduation I have been unable to find a job. I have sent in over 150 applications in the past year that resulted in 5 interviews and no job. As a student I was told to get a job in a hospital to "get my foot in the door", with my CNA and phlebotomy certs I was able to obtain a position as an ER Tech in my local hospital but have been passed over several times for X-ray job in the almost year I have been employed. I have come to love my ER and crave more responsibility, unfortunately my x-ray training is of no use to my position. My employer however has a program in which they will pay my tuition for a BS degree in nursing that is paid back not with money, but in time ($5000/yr.). I am highly considering this option as they would be required to give me a full time job at graduation or I owe them nothing. However even with my A.S in radiography I would still need 5 pre reqs (co reqs), and 3 years of nursing school. My question is has anyone ever attempted or known someone who has attempted this transition? I know having both my RN and my RT(R) would be of use in an OR or Cath Lab but is there any other job where both would be of use? Could I earn a higher salary with both registries or will my A.S. have pretty much been a waste of time and tons of money?
