A clinical nurse, often known as a clinical nurse specialist, is a highly trained nurse leader who focuses on a certain area of practice. Clinical nurses assist other nurses in their job and promote health-care innovation within their organizations and communities. Clinical nurse specialists can order tests, run some diagnostic tests, administer basic treatments, and prescribe drugs in some states. They may also provide expertise and support to a group of nurses. They frequently contribute to the development of organization practices modifications and plans to guarantee the group is implementing best practices and providing evidence-based care. CNSs are trained to identify health-care inadequacies or gaps. They may offer consultations, engage with patients and their families, monitor treatment, plan and execute interventions, and assess overall health-care delivery.
