Final answer:
C) problems in performing activities of daily living. The need for long-term care in older persons is generally determined by problems in performing activities of daily living (ADLs) and loss of cognitive skills.
Step-by-step explanation:
The need for long-term care in older persons is generally determined by problems in performing activities of daily living (ADLs) and loss of cognitive skills, rather than the number or severity of medical conditions. ADLs include activities such as bathing, dressing, eating, and mobility, and difficulties in performing these tasks can indicate the need for long-term care. Loss of cognitive skills, such as memory loss and decline in thinking abilities, can also impact an older person's ability to live independently and may require long-term care.
