Personal care assistants, also known as caregivers, home health or personal care aides, give assistance to people who are sick, injured, mentally or physically disabled, or the elderly and fragile. They work in the home and help their clients with daily activities, such as bathing and bathroom functions, feeding, grooming, taking medication, and some housework. PCA's help clients make and keep appointments with doctors, provide or arrange transportation, make and serve meals, make sure they take their medicine and serve as a companion for their clients.
