You probably have your reasons for leaving, but it's worth mentioning- an RN in the military ranks as an officer, and gets paid accordingly. I have two friends who served as RN's, one in the AF, and one in the army. Both said that they loved it.
In nursing school we practiced range of motion, transferring, and bed bathing on each-other, (fully-clothed and without water). I did an EKG on my lab partner, (who is now my wife
) in school. We all practiced drawing up and injecting saline into each-other in one lab, however, I never did an IV until I began working.
There's a good thread on the male-female issue in the men's forum.
