ADN to MSN programs...

Interesting concept here. I have heard of programs that will take a person from an ADN to an MSN by making the student take baccalaureate level nursing courses, granting equivalency to the BSN, and then allowing the student to take the graduate level courses to obtain the MSN/NP designation. The kicker is that some of these programs do not grant a BSN in the interim but will grant the MSN. Why would the schools not grant a BSN too? How do you explain this to employers and academia..."Well, I have an associate of science in nursing and a master of science in nursing, but I don't have a BSN, or any other bachelor's degree for that matter." What do you all think? It seems a little odd to me.
