Advanced nursing practice.

: Advanced OR nursing practice is emerging and the roles, responsibilities, relationships, and rewards are spread over preoperative, operative, and postoperative work units. The roles of the nurse in advanced practice are multidimensional: clinical, collegial, educative, investigatory, and administrative. Though the primary allegiance of the ANP is to nursing, she has a commitment and the skills to work collaboratively with other nurses and disciplines on the surgery team.
