What Does a Nurse Practitioner Do?

Nurse practitioners (NPs) are advanced practice registered nurses who provide primary care. Their advanced education lets them take on tasks usually associated with physicians: diagnosing conditions, treating illness and injury, and prescribing medications. In communities with limited healthcare access, especially rural ones, NPs often serve as the primary care provider. Most specialize in a patient population, working with children, adults managing diabetes, acute care patients, or others depending on their focus.

What an NP Does Day to Day

Responsibilities vary by specialty but generally include patient assessment and exams, reading test results, diagnosing conditions, prescribing medications, treating illness and injury, and providing health education.

Many NPs work in physicians' offices, but the role also shows up in hospitals, rehabilitation centers, home healthcare, long-term care, and universities. Demand is climbing fast: BLS projects 40% growth from 2024 to 2034, which should open opportunities in places like urgent care centers and corporate settings.

The most common specialty is family nurse practitioner (FNP), which offers the broadest scope of practice. FNPs are trained to care for people across the lifespan, from newborns and children through adults, pregnancy, and end-of-life care.

Are Nurse Practitioners Registered Nurses?

An NP is an RN with advanced education and broader responsibilities, which means more autonomy and a wider scope of practice. You don't have to work as an RN before earning your NP license, but the experience helps, depending on how well it aligns with your NP specialty. ICU experience translates well if you plan to work in the ICU; it's less useful if you're heading into dermatology. Either way, an RN background gives you a foundation in treating the human response, and NP training adds the knowledge of treating the disease process on top of it.

Jobs You Can Hold as an NP

Your specialty largely determines your career path.

Acute Care NP. Works in emergency rooms, trauma units, and urgent care. Diagnoses and treats injury and illness, providing care from admission through discharge, including stabilizing patients in emergencies like a stroke, and guides families on next steps.

Adult NP. Works in physicians' offices, corporate offices, urgent care, and hospitals as a primary care provider for adults, performing exams, diagnosing, prescribing, and treating. Often a rural role where the NP practices without on-site physician supervision.

Psychiatric-Mental Health NP. Works in mental health offices and psychiatric hospitals, assessing and diagnosing mental health conditions, building treatment plans, prescribing, and counseling. In states with full practice authority, these NPs can run their own practices.

Family NP. Works in physicians' offices and hospitals with patients of all ages, handling exams, diagnosis, treatment, and prescriptions. The most common specialty, thanks to its broad scope.

Pediatric Primary Care NP. Works in physicians' offices, schools, and hospitals with patients from infancy through the teen years, performing exams, diagnosing, recommending treatment, prescribing, giving vaccinations, and tracking healthy development.

What's Behind the Demand

NP job growth is projected to far outpace overall healthcare hiring. Part of it tracks the aging baby boomer population, but the bigger driver is primary care access, especially in rural areas where losing a single provider forces residents to travel much farther for care. With fewer physicians choosing and staying in family medicine, NPs are filling the gap. The majority of NPs specialize in primary care and stay there, and the shorter training path compared to medical school makes the role an attractive alternative for students who want flexibility once they hold an advanced license.

Education

You'll need at least a Master of Science in Nursing (MSN) to practice, though there's a growing trend toward the more advanced Doctor of Nursing Practice (DNP). The first step is an RN license in good standing, which every NP program requires; many also want a few years of clinical RN experience. From there you earn an advanced degree, pass a specialty exam, and apply for state licensure.

Practice Authority

In some states NPs can open their own practice and see patients without a physician present. In others, NPs work under physician supervision, often in large physician-owned offices, seeing patients independently but formally supervised. As of 2025, more than two dozen states plus Washington, D.C., grant NPs full practice authority, and the count has continued to climb.

States also set your prescriptive authority, your ability to prescribe medication. Some grant full authority; others restrict controlled substances. Pennsylvania, North Carolina, and Illinois, for example, limit NPs to a 30-day supply of Schedule II controlled substances such as fentanyl, hydromorphone, methadone, and oxycodone.

What You Can Earn

NPs earn considerably more than RNs, reflecting the added education and responsibility. Actual pay depends on your specialty, where you live, and regional demand.

Is the Job Right for You?

An NP carries far more responsibility than most nurses. Since you'll often be a patient's primary care provider, you need to be confident, decisive, and able to make hard calls. The role suits people who are analytical, compassionate, dependable, and good listeners, with strong problem-solving, decision-making, ethical, critical-thinking, and interpersonal skills.
