What Is a Family Nurse Practitioner and How Are They Different from Primary Care Physicians?

Nurse Practitioner vs primary care doctor

When most people think of visiting a healthcare provider, they often picture a doctor in a white coat. But in many clinics, especially community health centers, there's a good chance the provider you’ll see is a family nurse practitioner (FNP).


While some patients may feel unsure about receiving care from a nurse practitioner instead of a physician, it’s often because they’re unfamiliar with the rigorous education, training and certifications FNPs must go through before they can see patients.


At St. Hope Healthcare, we have many highly qualified family nurse practitioners delivering exceptional primary care alongside our doctors. They’re a key part of our highly qualified and dedicated healthcare team.


What Is a Family Nurse Practitioner (FNP)?

A family nurse practitioner (FNP) is an advanced practice registered nurse (APRN) with specialized training in family and primary care. FNPs are licensed to diagnose conditions, treat illnesses, prescribe medications and provide preventive care across patient lifespans, from infants to seniors.


FNPs bridge the gap between nursing and medicine. They are holistic in their approach, often spending more time with patients and focusing on both physical and lifestyle factors that affect overall health.


Education and Training of FNPs

To become an FNP, a nurse must:


  1. Earn a Bachelor of Science in Nursing (BSN)
  2. Become a licensed Registered Nurse (RN)
  3. Complete a Master’s or Doctoral program in Nursing focused on Family Practice
  4. Pass a national certification exam to become board-certified

This advanced education includes coursework in pharmacology, pathophysiology, advanced health assessment and clinical rotations in family practice settings. Many FNPs also pursue Doctor of Nursing Practice (DNP) degrees, which further emphasize clinical leadership, research and evidence-based practice.


What Can FNPs Do?

FNPs are licensed to provide comprehensive primary care. Their scope of practice varies slightly by state, but in many states, including Texas, they have full or partial practice authority under collaborative agreements with physicians. Some of the things FNPs can do include:


  • Diagnose and treat illnesses (from common colds to chronic conditions)
  • Prescribe medications and manage prescriptions
  • Order and interpret lab tests and imaging
  • Provide immunizations and health screenings
  • Offer guidance on nutrition, mental health and lifestyle changes
  • Manage chronic diseases such as diabetes, asthma or high blood pressure
  • Refer patients to specialists when needed


FNPs often develop strong relationships with patients and families, emphasizing patient education and preventive care.


FNPs vs. Primary Care Physicians: What’s the Difference?

In Texas, FNPs have restricted prescriptive authority, meaning they can prescribe medications, including controlled substances, but must do so under a collaborative agreement with a supervising physician. PCPs, on the other hand, have full prescriptive authority.


Licensing also differs: FNPs are licensed as APRNs and board-certified in their specialty area, while PCPs are licensed and board-certified as medical doctors. While physicians have a full scope of medical practice, FNPs can still provide a wide range of primary care services and often act as the main healthcare provider, particularly in underserved areas where physicians may be in short supply.


Why Should You Feel Comfortable With an FNP Instead of a Medical Doctor?

There are many reasons patients should feel confident that an FNP at St. Hope Healthcare is providing top-quality care:


  • They take time to listen. FNPs are known for their approachable, patient-centered style.
  • They focus on prevention. FNPs often guide and support patients in making long-term lifestyle changes.
  • They’re accessible. In many clinics, you can get an appointment with an FNP faster than with a physician.
  • They offer continuity. Many patients develop long-term relationships with their FNP, just as they would with a family doctor.


At St. Hope Healthcare, our family nurse practitioners are experienced, compassionate professionals who deliver the same high standard of care as physicians. Whether you need a routine check-up, treatment for an illness or help managing a chronic condition, our FNPs are here to help.
