Which is an advanced practice registered nurse with a master's or doctoral degree who has a dramatically expanded scope of practice beyond the registered nurse?

• A. Certified Nurse Midwives
• B. Nurse Practitioners
• C. Certified Registered Nurse Anesthetists
• D. Clinical Nurse Specialists

Answer: (B)

Advanced practice registered nurses with master's or doctoral degrees are prepared to go beyond routine nursing care by taking on complex clinical responsibilities, including assessing patients, diagnosing conditions, ordering and interpreting tests, and prescribing treatments. Among the roles listed, the nurse practitioner is the one designed to provide broad, primary and specialty care across various populations. They often serve as a first contact for patients, manage ongoing health problems, and coordinate care with other professionals, which embodies a substantially expanded scope of practice beyond a traditional registered nurse.

The other roles are specialized within the APRN family: certified nurse midwives focus on obstetric and gynecologic care and childbirth; certified registered nurse anesthetists specialize in providing anesthesia; clinical nurse specialists provide expert practice in a specific clinical area and may concentrate on improving care processes and outcomes within a specialty. While all have advanced training, the nurse practitioner most clearly aligns with broad, independent clinical practice across many settings.
