Functional changes refer to which aspect of an older adult's daily life?

• A. The ability to perform activities of daily living
• B. The older adult's nutrition status
• C. Sleep patterns
• D. Mobility limitations

Answer: (B)

Functional changes in daily life are best understood through how nutrition affects a person’s energy, strength, and ability to participate in everyday tasks. When an older adult’s nutrition status changes—such as poor appetite, inadequate intake, unintended weight loss or gain, or dehydration—these shifts directly influence daily functioning: energy for activities, ability to prepare and eat meals, and overall stamina to maintain routine. So, nutrition status is the aspect most closely tied to changes in how daily life is experienced. While ADLs, sleep, and mobility are also part of daily functioning, the item highlights how nutritional health specifically impacts day-to-day functioning, making nutrition status the best fit.
