A geriatric nurse is an RN (registered nurse) that provides care exclusively to elderly patients. They have specific training in elderly care and have studied gerontological research and practices. As a geriatric nurse, your duties are to monitor and treat patients with a variety of issues and diseases that afflict older people, such as advanced diabetes, cancer, cardiovascular disease, dementia, and hearing issues. You should be trained to help your patients deal with the vast physical and mental changes that accompany aging. In your work, you collaborate extensively with doctors and other physicians to assess patients and provide care and education about their conditions.
