An older adult client arrives at the clinic reporting decreased strength in knees and in handgrips. Which action should the nurse include in a functional assessment of the client?

A. This action pertains more to discussions about advance care planning and end-of-life preferences, which may be important but are not directly related to assessing the client's functional status. B. Episodes of sundowning are associated with changes in behavior, confusion, and agitation in some individuals with dementia, particularly in the late afternoon or evening. While important to assess in certain contexts, it is not directly related to evaluating the client's physical strength and mobility. C. Asking the client to lie still does not provide information about their functional status or ability to perform activities of daily living. D. This is the most appropriate action because it directly addresses the client's reported decreased strength and assesses the impact on their functional ability. Falls are a common consequence of reduced strength and mobility in older adults and can provide valuable information about the client's current physical function and safety.
