Who is a "nurse"?

A nurse is a healthcare professional who provides various levels of patient care under the supervision of doctors and other medical professionals. Nurses help with patient evaluations, giving medications, monitoring vital signs, providing treatments, and educating patients and their families about health conditions and self-care. Nurses work together with other members of the healthcare team to make sure patients receive thorough care. They can specialize in various areas, such as pediatric nursing, critical care nursing, psychiatric nursing, or community health nursing, among others.
