I recommend that you keep plugging ahead, study harder, graduate, and find a job in a setting that appeals to you. I think you may be a burnt out and looking at the grass on the other side of the fence. Sure, it may be greener, but ask yourself what is fertilizing it. Look at why you're struggling and work to improve your performance.
You would find a lot of the same negatives such as outdated information, poor instructor to student ratios, etc. in nursing programs
, particularly as they buckle down further due to dwindling budgets. Imagine being in a program with similar problems that also provides you with much less clinical experience. You would have to take out a lot of debt to do a BSN and then a DNP, too. By finishing your PA program you'll be able to get working much faster.
Do you really want to work as an RN, which you would have to do prior to making it through a MSN/DNP program? It's very difficult for new graduates to find decent work. Nurse to patient ratios are likely to get worse as reimbursement drops. I'm blessed in that I love my current RN job (PACU), but most of the nurses I know in other departments tolerate theirs at best. And I'm in a pretty darn good hospital. You seem to think that working as a nurse first will be a big advantage. Depending upon what type of job you're able to land and how overworked, and understaffed you are it might not really do all that much to prepare you that you can't get by busting your butt in your PA program's clinical rotations.
Go read some of the threads in the nursing forums to get a feel for some of the negatives of nursing. It's a lot better to deal with an angry drug addict as a PA/NP than as an RN. I don't say that to rag on nursing, but it's important to be honest about the pros and cons.
I think you've got a fantasy of what NP practice is vs. PA practice. The bottom line is that you can't get reimbursed for touchy-feely stuff. That's not to say you shouldn't be sensitive or considerate of all of a patient's needs, but you have to understand that you have to keep the lights on in the practice and be able to make payroll. As reimbursement is slashed further and further, especially for Medicaid and other sources who seem to provide coverage for those in greatest need for more comprehensive care, there is going to be a push to see more and more patients in less time.
