I think your decision should be based on what you want to do with either degree.
What are your future career goals and plans?
See American Medical Informatics Association (AMIA) http://amia-niwg.org/NI_Education_Programs1.htm
for a list degree programs and certifications in Nursing and Informatics.
You also might check out univesities and colleges in your community. New programs are sprouting up all over the country not to mention on-line courses, degrees and certificaitons.
