Nurse Practitioners assess, diagnose, treat and monitor a wide range of health problems using an evidence based approach to their practice. They consult and collaborate with other health care professionals to meet the needs of the patient population. Chronic disease management, health promotion and illness prevention, as well as helping patients navigate through the health care system are integral to their approach to patient care. Engaging patients as full partners in their care plan with attention to self-care to the extent that patients are willing and able to participate is an important aspect.
