The nurse is performing a functional assessment on an older client who lost five pounds (2.27 Kg) of weight since the last visit 12 weeks ago, and who reports a decrease in energy and appetite. Which action should the nurse include during the assessment?

A) Incorrect - Requesting the client to lie still may be relevant for certain assessments, but it is not specific to the situation described in the question. B) Incorrect - Inquiring about episodes of sundowning is more relevant for clients with cognitive impairment and is not directly related to the client's weight loss and decreased energy and appetite. C) Correct - Questioning the client about the frequency of falls is important, as falls can contribute to weight loss, decreased energy, and appetite changes in older adults. D) Incorrect - Assisting the client with clarifying values about end-of-life care is a valuable nursing intervention but is not the priority in this assessment scenario.
