Home Care Clinical Specialist – OASIS (HCS-O) Certification Practice Test

ADL stands for Activities of Daily Living, the basic self-care tasks essential for daily independence. These include activities like bathing, dressing, transferring, toileting, continence, and feeding. This term is the best fit because it names the fundamental daily tasks people must perform to care for themselves. In contrast, IADL refers to more complex, instrumental tasks such as managing finances, transportation, shopping, meal preparation, and medications, which go beyond basic self-care. Physical ability and cognitive ability describe capacities rather than the actual daily activities themselves.
