Sorry you haven't gotten a response yet.
Nursing care MUST be under the direction of the Chief Nursing Officer -- in order to comply with CMS & JC regulations. Soooo - nurses who work in specialty areas (that are outside the areas under the control of the CNO) have to have a two-part supervision. Their day-to-day work (attitude, appearance, attendance, etc) is managed by the department manager but the "nursing care" must be managed & evaluated by a qualified nurse manager.
Most facilities do this with a matrix-type arrangement. You would be invited to participate in any activities that are intended to establish & maintain the organization's nursing standards (Quality, policy, task forces, etc) so that you have a solid connection to Nursing and are aware of the rights & responsibilities of nursing staff. Your (non nursing) supervisor would have to have the "qualified nurse manager" complete the part of your annual eval that pertains to nursing practice.
