How many different ways can you go from a 68C to RN in the army active duty? my ultimate goal is to be a PA?

Then just apply to IPAP. Skip all the nursing

Those are two unrelated path and goals. You do not need to go from LVN to RN then to PA school. You can go to the Army’s PA school with whatever minimum requirements are listed. If your goal is to be a PA don’t waste your time and the Army’s money by getting your BSN.

If your goal is PA, don’t bother with getting an RN degree; apply for the Interservice PA program directly. If your goal is to diagnose and treat patients, you could go the RN route then continue on to become a nurse practitioner. Depending on your post-military plans, nurse practitioners tend to have more opportunities for independent practice as they can be licensed and do not have to be under supervision of a physician. Of course do not discount the idea of attending medical school. The Uniformed Services University in particular looks favorably on prior service.
