Holitic nursing is being taught, at least where I got my degree. I think it IS catching on, though we don't really 'call' it Holistic Nursing as such. We, as nurses, see the 'whole' patient, or as much as we can in the hospital. Quite often, we see the 'whole' person in LTC. There is a Journal for Holistic Nursing out there.....
Good luck in the course, and keep us posted!
