Which degree plan should I follow for Healthcare Informatics?

I'm an RN who has basic computer knowledge who is interested in entering the IT field. I live in Houston, and I'm looking at various degree plans. I don't have a bachelor's degree yet. I'm considering getting my BSN just to have it and so anything past that can be considered postbacclaureate, taking only major-specific classes to go for another degree.

1) BS in Information Systems Technology at UH. This has no healthcare-related classes, but it is a bachelor's degree and I've taken many of the pre-req classes required. This would also come in handy for working non-healthcare related fields.

2) Associate's Degree in Health Information Technology. Health Informatics aren't so hot in the job market right now, and I really want a bachelor's, so I'd maybe do this after getting a bachelor's in nursing or IT.

3) There are certificate programs in HIS for people with bachelor's degrees available, as well as graduate degrees.

Right now, I'm really not familiar with HIS. All I know is that I'm not computer-illiterate (I have a MacBook Pro dual formatted). Should I go for a BSN or a BS in IST?
