This year the ANCC (American Nurses Credentialing Center) recognized the HN-BC (Holistic Nurse-Board Certification). That says alot.
Holism is not New Age, it's actually nursing at it's antiquity. Read what Nightingale thought about taking care of the whole person. Look past her views on how a nurse should dress (this was the 19th century). Remember how she was an adminstrator of the finest, documenting the observations she made on the soldiers in Crimea. Look at her nursing theory. If one changes the environment that surrounds the client, then the nurse is placing the client in the best place for the body to it's own healing. We do not heal, the client does this. But the nurse (or doctor, therapist, etc) places the client in the best possible climate for this to occur. For example,
the client presents with a fracture of the radius. Very common. Would this person heal without the nurse or doctor. Yes, eventually. The body would repair it. This is what bodies do. Of course it may not heal well, or be as usable a limb as before. This is why the doctor sets the fracture, the ortho tech or Nurse applies the cast or splint, then the therapist teaches/performs ROM exercises to allow the break to heal in a better environment.
Be very proud you chose to attend a progressive school that models holistic care.
The school I attended did as well, & has kicked it up a notch (to borrow from Emeril's sayings) since this is what the client population desires & it is fiscally responsible.
