Nurse Practitioners (NPs) are advanced practice registered nurses who provide a wide range of healthcare services. They can diagnose and treat illnesses, prescribe medications, and manage patient care, often working independently or alongside doctors. NPs focus on health promotion, disease prevention, and patient education, making them essential in various healthcare settings, including hospitals and clinics. With their extensive training, NPs can specialize in areas such as pediatrics, family medicine, or gerontology. They play a crucial role in improving access to healthcare, especially in underserved communities, where they help bridge the gap between patients and medical resources.
