The roles and responsibilities of a geriatric nurse include providing specialized care to older adults that addresses their complex physical and mental health needs. Geriatric nurses work in various settings like hospitals, nursing homes, and patients' homes. Their responsibilities involve assessing patients' health status, understanding health issues, educating patients and families, and linking patients to community resources to help older adults stay independent for as long as possible. Geriatric nurses play an important advocacy role in the care of older patients.
