A client tells the nurse that he sees a chiropractor every week to help with back and leg pain. The major principle underlying chiropractic therapy is that:
 
  a. movement keeps the body's life forces in correct balance and flow.
  b. the brain sends vital energy to every organ in the body via the nerves originating in the spinal column.
  c. an imbalance in the energy fields causes discomfort and disease.
  d. the body is divided into ten equal, longitudinal zones that run the length of the body from the top of the head to the tip of the toes.
