A nurse practitioner (NP) is a registered nurse with advanced education and training, typically holding a master's or doctoral degree in nursing. NPs are qualified to provide a range of healthcare services, including diagnosing and treating illnesses, prescribing medications, and managing patient care. They often work in various settings, such as hospitals, clinics, and private practices. Nurse practitioners focus on patient-centered care, emphasizing health promotion and disease prevention. They can specialize in areas like pediatrics, family medicine, or gerontology, allowing them to cater to specific populations. NPs play a vital role in the healthcare system, often serving as primary care providers.
