Which statement best summarizes the nurse practitioner’s scope of practice?

• A. Nurse practitioners primarily perform basic health screenings
• B. Nurse practitioners diagnose, treat illnesses, and manage patient care
• C. Nurse practitioners work only in hospital settings
• D. Nurse practitioners perform physical exams, diagnose, treat illnesses, and interpret labs

Answer: (D)

The main idea here is that nurse practitioners have a broad, hands-on clinical role that covers the full cycle of patient care. They perform physical examinations to assess health, make diagnoses, decide on and implement treatments (often including prescribing medications), and interpret laboratory and diagnostic results to guide management and monitor progress. This description best captures the actual scope of practice, which goes beyond just screenings and isn’t limited to hospital settings.

The other statements are narrower or inaccurate: focusing only on basic screenings underestimates what NPs do; limiting practice to hospital environments ignores the many outpatient, clinic, and community settings where NPs provide care.
