1. Describe the APRN Consensus Model and the APRN practice The APRN Consensus Model is a framework that defines the roles, education, certification, and licensure of advanced practice registered nurses (APRNs) in the United States. The model aims to promote consistency and quality of APRN practice across different states and settings. The model identifies four roles for APRNs: nurse practitioner (NP), clinical nurse specialist (CNS), certified nurse-midwife (CNM), and certified registered nurse anesthetist (CRNA). Each role has a specific population focus, such as family, adult-gerontology, neonatal, women's health, etc. The model also establishes the criteria for APRN education programs, national certification exams, and state licensure requirements. The model requires that APRNs complete a graduate degree program that prepares them for one of the four roles and one of the population foci. The program must include core courses in advanced physiology/pathophysiology, advanced health assessment, and advanced pharmacology. The program must also provide clinical practice hours that are supervised by qualified preceptors. After completing the program, APRNs must pass a national certification exam that corresponds to their role and population focus. The exam must be administered by an accredited certification body that is recognized by the state board of nursing. The exam must test the APRN's knowledge, skills, and abilities in their chosen specialty. Once certified, APRNs must obtain a state license that authorizes them to practice in their role and population focus. The license must be consistent with the national certification and follow the state's scope of practice regulations. The license must also include the authority to prescribe medications and order diagnostic tests. The APRN practice is the application of the APRN's knowledge, skills, and abilities in providing care to patients within their role and population focus. The APRN practice is based on the standards of professional nursing and the ethical principles of autonomy, beneficence, nonmaleficence, justice, and fidelity. The APRN practice is guided by the best available evidence and incorporates the patient's preferences, values, and needs. The APRN practice is collaborative and interdisciplinary, involving consultation and referral with other health care providers as appropriate. The APRN practice is holistic and patient-centered, addressing the physical, mental, emotional, social, cultural, spiritual, and environmental aspects of health and illness. The APRN practice is accountable and responsible for the outcomes of care and the quality improvement of the health care system. 2.
