Navigating how to get the care you need can feel daunting at times, especially when you're not exactly sure who you should see.

Nurse practitioners have long played an important role in the health care system, but they're becoming increasingly vital as our collective health needs expand. In fact, if you've ever used a telemedicine service, you likely saw a nurse practitioner.

"Just like your primary care doctor, a nurse practitioner can play a valuable role in helping you maintain your overall health," says LaSondra Howard, a family nurse practitioner at Houston Methodist. "It is most common to find us in the primary care setting, but many also practice in specialty medical fields."

Still, you may still have a few questions about a nurse practitioner's role and capabilities, as well as what to expect if you're meeting with one in place of your usual doctor.

What is a nurse practitioner?

While not a medical doctor, a nurse practitioner is a highly trained medical provider who is qualified to provide a range of health services, including diagnosis and management of many common health complaints and conditions. They partner closely with your physician as part of your health care team.

Nurse practitioners undergo years of medical training, which includes nursing school, graduate education and hundreds of hours of clinical work. Many hold doctorate degrees in nursing.

"We practice in various health care settings, such as primary care offices, specialty clinics, hospitals, community health centers and more," adds Howard.

Some nurse practitioners have specialized training in specific medical fields, such as women's health, cardiology, acute care and more.

What types of conditions can a nurse practitioner treat?

Just like your primary care provider, a nurse practitioner can:

• Diagnose and treat acute illnesses and injuries
• Manage a broad range of chronic conditions, such as high blood pressure, diabetes, allergies and asthma
• Perform comprehensive annual exams
• Prescribe medications
• Provide referrals to a specialist
• Order and interpret labs and tests

"Today, it's very common for a primary care office to have at least one nurse practitioner," says Howard. "While we can independently manage most health issues, there are times when collaboration with a physician or specialist is needed."

What should I expect during a visit with a nurse practitioner?

A visit with a nurse practitioner is like a visit with a physician.

"Expect a thorough review of your medical history, a physical exam, questions about your symptoms or health concerns and explanation of your care plan," Howard says. "We take time to answer your questions and discuss your goals to ensure you understand your health and treatment options."

Your nurse practitioner might also remind you of any preventive care needed, like screenings for cervical, colorectal or prostate cancer.

Can a nurse practitioner prescribe medications?

Yes, nurse practitioners are licensed to prescribe medications — though specific regulations and extent of this authority can vary by state.

"In Texas, for instance, a nurse practitioner's ability to write prescriptions requires a collaborative agreement with a supervising physician," adds Howard.

Regardless of each state's regulations, all nurse practitioners are highly trained in pharmacology and capable of managing patient medications.
