Holistic Nursing is a recognized specialty. Registered Nurses with a minimum of a Bachelor's degree may become certified in Holistic Nursing (just like a nurse can be certified in Med/Surg or Pediatrics). Becoming certified in Holistic Nursing is a far cry from being just a self-designated title, holding a certificate in an alternative/complementary therapy, or simply just "thinking in a holistic manner".
