I'm not an RN though I have a Bachelor's in Health Science and a minor in Accounting (and an Accounting certificate). In the mid 90's I took pre nursing courses though decided to go the Accounting/Finance route. I've worked at well known hospitals for 16 years - in Finance. The pay is great - though for me I've always wondered about becoming a nurse. So, I resigned from my job about a year ago (great income) to take the remaining prereq's and obtain my BSN. I think having both degrees will be suitable for me, I can obtain some clinical/bedside experience and then move in to low level managment. Other positions I've held have been in Quality, and another area that is appealing (and makes good income is Information Technology). I think you could make very good $$ in positions such a Quality RN analyst/coordinator, Employee Health Nurse, Case Manager, RN in Information Technology (Informatics), Accounting/Finance, etc. For the specialized positions, you may need to take a few classes (such as Accounting/Finance/IT) though the pay atleast in the hospitals I've worked at are pretty substantial.
Good luck in exploring career options.
