Which APN role is described as an expert clinician in a specialized area of practice?

• A. Clinical Nurse Specialist
• B. Nurse Anesthetist
• C. Nurse Practitioner
• D. Nurse Midwife

Answer: (A)

Clinical Nurse Specialist is described as an expert clinician in a specialized area of practice. CNSs focus their advanced nursing care in a defined specialty—such as oncology, critical care, pediatrics, geriatrics, or wound care—and use expert assessment, differential diagnosis, and targeted care planning to improve outcomes within that domain. They often act as clinical consultants to staff, lead evidence-based practice and quality improvement initiatives, and provide advanced care within their specialty. Other APN roles—nurse anesthetists, nurse practitioners, and nurse midwives—center more on anesthesia care, broad primary/acute care with prescriptive authority, and obstetric/gyn care, respectively, rather than a single, defined specialty area of practice.
