A Pediatric Nurse Practitioner (NP) is an advanced practice registered nurse (APRN) who specializes in providing healthcare to infants, children, and adolescents. They diagnose illnesses, prescribe medications, and develop treatment plans, often working in hospitals, clinics, or private practices. Pediatric NPs focus on preventive care, growth and development monitoring, and educating families on childhood health issues. They work both independently and alongside pediatricians to ensure comprehensive care for young patients.
