A daughter reports that her 81-year-old mother has stopped paying her bills on time and often forgets whether she took her pills, though she still bathes and dresses herself. Which functional area is impaired?
Show answer & explanation
Answer: D
Basic activities of daily living (ADLs): Incorrect. Basic ADLs (bathing, dressing, toileting, transferring, continence, feeding) are intact in this patient.
Mobility, balance and gait performance outside the home: Incorrect. Nothing in the history suggests problems with walking or transfers.
Sensory function and communication: Incorrect. The problems described involve complex tasks, not vision, hearing or speech.
Instrumental activities of daily living (IADLs): Correct. Managing finances and medications are IADLs (Lawton scale); IADL decline often precedes ADL loss and can be an early sign of cognitive impairment.
Katz ADLs = self-care basics; Lawton IADLs = phone, shopping, food prep, housekeeping, laundry, transportation, medications, finances. IADL loss should prompt cognitive screening.
