A nurse practitioner (NP) is an advanced practice registered nurse who can diagnose conditions, prescribe medications, order lab tests, and manage treatment plans, often serving as a patient’s primary healthcare provider. In many states, NPs practice independently without physician oversight, and more than 370,000 are licensed in the United States.
What NPs Do Day to Day
The core of an NP’s job looks a lot like what you’d experience at a doctor’s visit. They assess symptoms, perform physical exams, order and interpret lab work and imaging, make diagnoses, and build treatment plans. They prescribe medications. They also manage ongoing chronic conditions like diabetes, high blood pressure, and asthma, adjusting medications and monitoring how well treatments are working over time.
Beyond treating illness, NPs spend significant time on health promotion and disease prevention: counseling patients on lifestyle changes, screening for early signs of disease, coordinating referrals to specialists, and educating families about managing health conditions at home. This blend of clinical treatment and patient education is central to how NPs are trained. Their education emphasizes a “whole-person” approach, meaning they’re taught to consider not just the diagnosis but the broader context of a patient’s life, health goals, and circumstances when building a care plan.
How NPs Differ From Doctors and PAs
NPs are trained in a nursing model, which prioritizes holistic, patient-centered care. Physician assistants (PAs), by contrast, are educated in the medical model and train alongside physicians, with a focus primarily on identifying and managing illnesses. In practice, both can diagnose, treat, and prescribe, but the philosophical framework behind their training differs. PAs typically must practice under physician supervision in most states, while NPs have gained independent practice authority in a growing number of states.
Compared to physicians, NPs complete significantly less clinical training before entering practice. Most physicians finish four years of medical school followed by three to seven years of residency. NPs complete a master’s or doctoral degree over two to three years, with 500 to 750 hours of clinical training, and are not required to complete a residency. NP programs also lack the standardized clinical training requirements that medical education follows. That said, research consistently shows that NP-led care delivers quality comparable to physician-led care, with similar chronic disease control, high patient satisfaction, and no significant differences in total costs. In some settings, NP care is associated with lower hospital readmission rates and fewer emergency department visits.
Where NPs Specialize
NPs don’t practice under a single general license. They earn board certification in a specific population or clinical focus, and their scope of practice is tied to that certification. The most common specialties include:
- Family Nurse Practitioner (FNP): The broadest certification, covering patients from prenatal through older adulthood. FNPs are the most common type and frequently serve as primary care providers in clinics and community health centers.
- Adult-Gerontology Primary Care NP: Focuses on adolescents through elderly adults, often working in internal medicine or geriatric settings.
- Psychiatric-Mental Health NP (PMHNP): Diagnoses and treats mental health conditions across all age groups, including prescribing psychiatric medications. This specialty has grown rapidly as demand for mental health providers has surged.
- Pediatric NP: Specializes in care for infants, children, and adolescents.
- Emergency NP: A newer specialty certification for FNPs who work in emergency departments and urgent care settings.
Other NPs work in acute care hospital settings, women’s health, oncology, or cardiology, though the certifications above represent the primary board-certified tracks.
Education and Licensing Requirements
Becoming an NP requires first earning a bachelor’s degree in nursing and passing the registered nurse (RN) licensing exam. Most NP candidates also work as RNs for some period before entering graduate school, though this isn’t universally required. From there, NPs complete a master’s degree (MSN) or a Doctor of Nursing Practice (DNP) program, which takes two to three years and includes 500 to 750 clinical hours of supervised patient care.
After finishing their degree, NPs must pass a national board certification exam in their chosen specialty. Certification is required for state licensure. Whether an NP can then practice independently or must work under a physician’s supervision depends entirely on state law. As of recent years, more than half of U.S. states grant NPs full practice authority, meaning they can evaluate patients, diagnose, and prescribe without a formal agreement with a physician.
Where NPs Work
NPs practice in nearly every healthcare setting. Primary care clinics are the most common workplace, but NPs also staff urgent care centers, hospitals, specialty practices, school-based health clinics, retail health clinics, Veterans Affairs facilities, and telehealth platforms. In rural and underserved communities, NPs frequently serve as the only available primary care provider, making them critical to healthcare access in areas with physician shortages.
Job Growth and Salary
The nurse practitioner field is one of the fastest-growing in healthcare. The Bureau of Labor Statistics projects 40% job growth for NPs between 2024 and 2034, far outpacing most other occupations. The median annual salary for nurse practitioners was $129,210 as of May 2024, though pay varies by specialty, geographic region, and practice setting. PMHNPs and NPs in acute care or surgical specialties tend to earn at the higher end of the range.
