Which of the following is classified as an activity of daily living (ADL)?

Bathing is classified as an activity of daily living (ADL) because ADLs refer to the basic tasks essential for self-care and personal hygiene that are necessary for an individual's daily functioning. This category typically includes tasks such as feeding, dressing, grooming, toileting, and bathing, which are fundamental for maintaining personal health and well-being.

In contrast, the other activities listed—cooking, shopping, and reading—are not considered ADLs. Cooking involves preparing meals, which is more of an instrumental activity of daily living (IADL) that supports independent living but is not essential for basic day-to-day survival. Shopping also falls into the IADLs category, as it relates to procuring food and other supplies rather than personal care. Reading, while an important cognitive and leisure activity, does not pertain to self-care tasks and therefore does not fit into the definition of ADLs.
