I have been an RN for 18 years. Earned ADN, then BSN, then MSN/MHA. During my career I have gone from staff nurse to hospital CEO. And I most definitely consider my administrative role as a continuation of my nursing practice.
To answer the original question--go for the BSN.
Whether nurses choose to believe it or not, our profession (or should we say quasi-profession) is a target for being greatly reduced and possibly eliminated. Why? Consider the following:
The people that run healthcare in this country are not clinicians. The people that run it are the people that control the money. Nursing salaries are the single most expensive line item for a hospital's operating cost. Administrators and corporate execs always ALWAYS look for ways to reduce cost and increase profits. With reimbursement cuts and demands for higher profits, these guys are getting desperate. Nursing is a target.
We must do a few things to counter this. One is to clearly define the one, single way a person can become a registered nurse. In the eyes of an administrator who is an accountant or MBA or MHA, how do you explain the difference between a nurse with a 3 year diploma, 2 year degree, 4 year degree, or a 6 year masters degree, when they are all qualified to essentially do the same things that will generate revenue for his hospital, they are all called "nurse" they all took the same NCLEX, and all are called RNs? LPNs finish a 1 year program but they are still called "nurse."
What if there were different ways to become an MD? You could do the 2 year program, or the 4 year program, and then after a while you could go back and do a residency in something. What would you think if you were in the doctor's office with your sick child who had severe diabetes and you asked the doctor about their eduation and the doctor said,"well, I finished the 2 year program and got my MD. I have been planning on going back to the fast-track 4 year program but I am also considering doing that online because it is more convenient. But I really want to do a residency of some kind, I am currently just a generic MD but I did go take some prep courses and got my certification in pediatric endocrinology."
If you are considering nursing school---go in with the mindset to become a professional registered nurse, get the broadest and most liberal education you can, and work extra hard to learn the hands-on, task oriented skills that make you immediately marketable. Don't worry too much about your hands-on skills, once you get out in the real world you will do so many tasks, so often and so quickly you will soon be able to do them in your sleep. But if you miss out on the broader education then you are robbing yourself, and the rest of nursing and healthcare, of a broad knowledge base and a more well rounded view of the world and the people that make up the world. You will find soon enough that communicating and relating to people, and the concept of EQ, is just as important to your success as the task oriented hands on skills.
