Which of the following is NOT an activity of daily living?

Activities of daily living (ADLs) refer to the basic tasks that individuals typically perform on a daily basis to take care of themselves. These activities are essential for self-care and are often used in determining an individual's ability to live independently.

Bathing, dressing, and toileting are all fundamental ADLs. Bathing refers to the ability to wash oneself, dressing involves putting on and taking off clothing, and toileting includes managing personal hygiene in the restroom. These activities are critical for personal care and health maintenance.

On the other hand, bathtub maintenance does not fit the definition of an ADL. It involves cleaning and maintaining the bathtub itself, which is a household chore rather than a personal care task. This distinction highlights that while maintaining a clean living environment is important, it is not classified as an essential self-care activity that defines an individual's functional capabilities. Thus, bathtub maintenance stands out as not being an activity of daily living.
