Advanced nurses have obtained an advanced level of education and can perform tasks that a registered nurse cannot. Some tasks of an advanced nurse include diagnosing and treating illness as part of a health care team. Some nurses focus on health promotion and disease prevention, and some may order, perform, or interpret diagnostic tests. Others are educators, teaching students how to care for patients.

Nurses provide care for sick, injured or disabled people. They help people recover from sickness or injury. They may assess a patient’s health problems or help teach patients how to be healthy.
