A Nurse Practitioner is a Professional Registered Nurse who has advanced education and clinical training in a health care specialty. The Florida Board of Medicine designates the term for a nurse practitioner as A.R.N.P or Advanced Registered Nurse Practitioner. Most Nurse Practitioners have national board certification in their area of expertise and hold Masters or Doctoral degrees. Nurse Practitioners serve as primary health care providers for children and adults during health and illness. Their goal is to help people of all ages stay as healthy as possible. They do this by teaching people and treating their acute illnesses (such as infections) and chronic disease (such as hypertension, diabetes, and many others).
