What Is a Nurse Practitioner and What Do They Do?

A nurse practitioner is a registered nurse who has completed advanced graduate-level education and clinical training beyond a standard nursing degree.
In this guide, you'll learn:
- Nurse practitioners can typically diagnose conditions, order and interpret diagnostic tests, and create treatment plans, subject to the scope of practice rules in their jurisdiction.
- Scope of practice for nurse practitioners varies significantly depending on the state or country, ranging from full independent practice to required physician collaboration.
- Common specializations include family practice, acute care, psychiatric-mental health, and pediatrics, each requiring focused clinical training.
- The role sits between registered nursing and physician practice, combining nursing's patient-centered approach with expanded clinical authority.
1What Is a Nurse Practitioner?
A nurse practitioner is a registered nurse who has completed additional graduate-level education, typically a master's or doctoral degree, along with supervised clinical training that qualifies them for an advanced practice role. This training allows them to take on responsibilities that go beyond what a standard registered nurse handles.
In many healthcare systems, nurse practitioners serve as a primary point of care, particularly in primary care, family medicine, and increasingly specialized settings.
2Core Responsibilities of the Role
The day-to-day responsibilities of a nurse practitioner typically extend well beyond traditional nursing duties into areas usually associated with physicians.
- Conducting patient examinations and taking detailed medical histories.
- Diagnosing acute and chronic conditions.
- Ordering and interpreting diagnostic tests such as bloodwork and imaging.
- Developing and adjusting treatment plans, which in many jurisdictions includes prescribing medication.
- Educating patients on prevention, chronic disease management, and lifestyle factors.
3Why Scope of Practice Varies So Much
One of the most important things to understand about the nurse practitioner role is that its scope of practice is not uniform. Different regions grant different levels of independence, and this has a direct effect on how the role functions day to day.
- Full practice authority: nurse practitioners can evaluate, diagnose, and treat patients independently, without a mandated physician relationship.
- Reduced practice authority: at least one aspect of practice requires a collaborative agreement with a physician.
- Restricted practice authority: state or regional law requires physician supervision for the nurse practitioner to provide patient care.

4The Education and Training Path
Becoming a nurse practitioner requires building on a foundation as a registered nurse and then completing focused graduate education aimed at advanced clinical practice.
This typically includes a bachelor's degree in nursing, licensure as a registered nurse, and then a graduate program combining advanced coursework in pharmacology, pathophysiology, and clinical assessment with hundreds of hours of supervised clinical practice in a chosen specialty.
5Common Nurse Practitioner Specializations
Nurse practitioners often specialize in a particular patient population or clinical area, which shapes both their training and their day-to-day work.
- Family Nurse Practitioner: primary care across the lifespan, from children to older adults.
- Acute Care Nurse Practitioner: care for patients with serious, often hospital-based, medical conditions.
- Psychiatric-Mental Health Nurse Practitioner: assessment and treatment of mental health conditions.
- Pediatric Nurse Practitioner: care focused specifically on infants, children, and adolescents.
6How Technology Shapes the Role Today
Like most of modern healthcare, the nurse practitioner role has been reshaped by technology. Electronic health records centralize patient history and make it accessible across care settings, and clinical decision-support tools help flag potential drug interactions or suggest relevant diagnostic pathways.
As data-driven tools become more common in healthcare, practitioners increasingly need at least a working familiarity with how these systems organize and surface information, even though the clinical judgment itself remains the practitioner's responsibility.
7Nurse Practitioner vs Physician: Key Differences
While the roles overlap in many clinical tasks, the underlying training paths differ. Nurse practitioners come from a nursing education background emphasizing patient-centered, holistic care, while physicians complete medical school and residency with a different curriculum and licensing process.
In practice, this means the two roles are often complementary within a care team rather than direct substitutes for each other, particularly in complex or specialized cases.
