Differences Between Nurses and Nurse Practitioners

"Nurse" is a general term covering many types of medical care responsibilities. Nurses perform a variety of duties and are found in almost every medical setting, from doctor's offices to hospitals to nursing homes and others.

Distinctions are made among the several types of nurses according to their education and their focus. All work with patients and their responsibilities are usually based on the amount of education they have.

Different Types of Nurses

The following are different types of nurses:

LPNs (Licensed Practical Nurses) and LVNs (Licensed Vocational Nurses) 

LPNs and LVNs study an extra year beyond high school and become licensed by the state they work in. Patients will encounter LPNs taking medical histories, recording symptoms, weighing and measuring, even giving injections. LPNs are often supervised by RNs (registered nurses) but may be supervised directly by doctors.​

Registered Nurses (RNs)

Registered nurses may have a two-year associate's degree, or may have finished a four-year bachelor of science degree in nursing (BSRN). They must then pass a national exam before they are licensed in their state. Their responsibilities are broader since they have more depth of training.

Patients may find RNs assisting with the more medical aspects of their care, such as administering some treatments, helping them manage their treatment plans, even explaining medical information or prevention strategies to them, or coordinating care with their families.

RNs may choose to advance their studies and careers into more specialized areas. They may become CRNAs (certified registered nurse anesthetists) or specialize in fields like cardiology, oncology, pediatrics or even forensics. They may also decide to become nurse practitioners (NPs).

Nurse Practitioners (NPs) 

Nurse practitioners, also called advanced practice registered nurses (APRNs) are usually the most educated of nurses. In addition to a bachelor's degree in nursing, they must also earn a master's or doctoral degree, often specializing as described above.

Differences Between RNs and NPs

The big difference between RNs and NPs is the degree of autonomy an NP is granted. While NPs are required to work under the auspices of a physician, in many states, NPs may diagnose and treat patients in an independent location, without the constant vigilance of a physician.

When they are the diagnosis and treatment decision-makers in place of the physician, they are called physician-extenders. They may write prescriptions and run medical tests; in short, they provide basic care to patients who have common ailments like colds or flu or rashes, or provide maintenance care for diabetics or heart disease patients, freeing up physicians so they can concentrate on more complex diseases and conditions.

There are disagreements about whether or not NPs should have a license to execute many of the functions they perform. Many people will tell you that increasing the number of NPs will help to solve the pending primary care crisis in the United States.

The American Medical Association has argued that NPs have too much autonomy and may cause problems for patients who need a higher level of expertise. NPs will argue back that they are trained and have honed the instincts to know when a patient needs to be referred to a physician or a specialist.

As for us patients, knowing the differences among nurses helps us decide who can provide us with the best advice and service for the medical problems we may experience.
