An NP is a nurse practitioner, a registered nurse with advanced graduate training who can examine patients, diagnose conditions, prescribe medications, and manage treatment plans. In many healthcare settings, an NP functions similarly to a physician and may be the primary provider you see for routine care, chronic disease management, or urgent health concerns.
What Nurse Practitioners Do
Nurse practitioners occupy a role that bridges nursing and medicine. They perform complete physical exams, record health histories, order and interpret lab work and imaging, diagnose acute and chronic illnesses, prescribe medications, and refer patients to specialists when needed. They also provide health education and counseling around lifestyle and disease prevention. In practical terms, if you visit a primary care clinic, urgent care center, or specialist office and are seen by an NP, your appointment will look much like one with a physician: a health history review, an exam, a diagnosis, and a treatment plan.
The scope of what an NP can do independently varies by state. Some states grant NPs full practice authority, meaning they can diagnose, treat, and prescribe without any physician oversight. Others require a collaborative agreement with a physician that outlines what the NP can prescribe and manage. A growing number of states allow full independence after a transition-to-practice period of supervised work following graduation. Regardless of the state model, NPs can generally prescribe controlled substances, order diagnostic tests, and serve as a patient’s primary care provider.
How NPs Are Trained
Becoming a nurse practitioner requires a master’s degree or a doctoral degree in nursing, earned on top of an existing registered nursing license. NP programs include a minimum of 500 supervised clinical hours of direct patient care, though many programs exceed that number. During training, NPs specialize in a specific patient population or care setting, and after completing their degree, they must pass a national certification exam in their chosen specialty before they can practice.
This training model is rooted in nursing rather than medicine. NPs learn to assess and treat patients through a nursing framework that emphasizes holistic care, health promotion, and patient education alongside clinical diagnosis and treatment. Physician assistants, by contrast, follow a curriculum modeled on medical school. Both can perform many of the same clinical tasks, but the educational philosophy differs. Physicians complete medical school plus residency, which involves significantly more total training hours.
Common NP Specialties
NPs don’t practice as generalists. They earn certification in a defined specialty that determines which patients they can see and what conditions they manage. The most common certifications include:
- Family Nurse Practitioner (FNP): Treats patients of all ages in primary care settings. This is the most widely held NP certification.
- Adult-Gerontology Primary Care NP: Focuses on adolescents, adults, and older adults in outpatient primary care.
- Adult-Gerontology Acute Care NP: Works with acutely ill adults and older adults, typically in hospitals or intensive care units.
- Psychiatric-Mental Health NP (PMHNP): Diagnoses and treats mental health conditions across the lifespan, including prescribing psychiatric medications.
Other specialties include pediatric primary care, pediatric acute care, neonatal care, and women’s health. Your NP’s certification tells you what population and complexity level they’re trained to handle.
Where NPs Work
You’ll encounter NPs in nearly every corner of healthcare. They staff primary care clinics, urgent care centers, emergency departments, hospitals, specialty practices, community health centers, and retail clinics. In rural and underserved areas, NPs frequently serve as the sole primary care provider for an entire community. They also work in schools, long-term care facilities, and telehealth platforms. The setting often depends on their specialty certification: a family NP is most likely in an outpatient clinic, while an acute care NP typically works in a hospital.
How NP Care Compares to Physician Care
A large body of research shows that NP-delivered care produces outcomes comparable to physician care across a wide range of measures. A 2024 analysis examined 117 systematic reviews representing over 1,600 original studies and found consistent evidence that NP care is equal to or better than physician care across multiple settings. Outcomes that have been directly compared include blood pressure and blood sugar control, hospitalization rates, emergency department visits, functional status, and mortality.
Patient satisfaction tends to run high with NP care. An analysis of nearly 54,000 patient survey responses found that satisfaction was higher for NPs than for other provider types. Multiple systematic reviews have reached the same conclusion: patients report equal or greater satisfaction when treated by an NP compared to a physician. This likely reflects the nursing model’s emphasis on education, counseling, and spending time with patients. For certain chronic conditions like cirrhosis, studies have found that patients managed by NPs had lower 30-day readmission rates and lower mortality risk.
NP vs. PA: Key Differences
If you’ve seen both “NP” and “PA” listed on a clinic’s provider page, the distinction matters less for your care experience than it does for their training background. Both can examine you, diagnose conditions, prescribe medications, and manage ongoing treatment. The core difference is educational: NPs train through a nursing model and must hold a nursing license before entering their graduate program. PAs train through a medical model with a curriculum patterned after medical school and enter the field from a wider range of undergraduate backgrounds.
In practice, NPs specialize during their training and are certified in a specific population (family, pediatric, psychiatric, acute care). PAs train as generalists and can switch specialties throughout their career without additional certification. Both work under varying levels of physician collaboration depending on state law, though the trend in many states has been toward granting NPs greater independence.
Job Growth and Salary
The NP workforce is expanding rapidly. As of 2024, roughly 320,400 nurse practitioners were working in the United States. The Bureau of Labor Statistics projects 40% job growth for NPs over the next decade, making it one of the fastest-growing occupations in the country. The median annual salary for nurse practitioners was $129,210 as of May 2024. Demand is driven by physician shortages in primary care, an aging population, and the expanding scope of practice laws that allow NPs to fill gaps in healthcare access.
