title: Sphere of Nursing Advocacy Model.
abstract: The Sphere of Nursing Advocacy (SNA) model explains and depicts nursing advocacy on behalf of a client. The SNA model views the client as continually protected from the external environment by a semipermeable sphere of nursing advocacy that allows clients to self advocate if the client is emotionally and physically able or to be advocated for by the nurse if the patient is unable to advocate for him- or herself. The SNA model can be used to guide research or it can provide the basis for instruction on the subject of nursing advocacy.
