I personally feel, and have no information to support this, that there is a difference b/w a BS+ADN and a BSN. Just as, taken to an extreme, there is a huge difference b/w a MS+ADN and a MSN. Think of it like this, apologies for my ignorance, if a person had a BS in geology and completes an ADN program, would they still have the educational equivalent of a BSN?
I think not. The BSN program I recently completed, as a 2nd degree student(BS in biochem), offered a seperate curricula in pharmocology, pathophysiology, growth and development, nutrition, physical assessment, ethics, leadership, and community health nursing in addition to med/surg (x2), peds, mother/newborn (OB/GYN) , and mental health. We also completed a minimum of ~1200 hours of clinical time along 5 semesters. The ADN program in my area would have only required me to complete 5 semesters of nursing, encompassing M/S, peds, OB, and MH, as credits from my prior degree would have satisified the rest of those needed for the ADN. I recognize that I may be glossing over the other course needed for the ADN and am not saying that either is better than the other. I am only using these two programs to illustrate that there is a difference b/w a BS+ADN and a BSN.
I also recall that one hospital would only consider your nursing degree for a pay differental.
