MSN/MBA or MSN/MPA

I'm going to be starting the process of applying for graduate school and I'd love some advice on which way to go. I have been a nurse in a CTU/CCU for a year and I already have a B.S. in Business Administration. Pursuing a MSN is a given. My question is should I go for the MBA or a Master's in Public Admininstration with an emphasis in Healthcare Administration. It seems and I've heard that MBAs are everywhere. I know of several nurses pursuing it. But if it furthers my career than I would definitely consider it. On the other hand, I don't know many with an MPA and I don't know if I should take a hint from that. Would the doors that open to me (if any) be any different with an MPA than a MBA? Any input would be much appreciated cause right now I feel its a toss-up. Thank you for your time.
Have you thought about the MHA? That is what I am currently getting, and employers seem to really like it. I would recommend the MBA if you want to keep your options open as far as employment; it's a much more general degree. If, however, you know you want to work in public administration, the MPA is a great idea. For myself, I have always known I wanted to be in health care administration, so the MHA was my choice. In sum, do the MBA if you are unsure of exactly what type of career path you want to take, and the MPA if you know for sure you want to be in public administration for the long haul. Hope this helps!
