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. Asking about sundowning may provide some insights into the client's cognitive state, but it is not directly related to the current concerns of weight loss, energy, and appetite. B. Requesting the client to lie still is unnecessary and may hinder the assessment of their overall functional status and mobility. C. Discussing end-of-life care options may be appropriate in certain contexts, but it is not a priority in assessing immediate functional status and nutritional concerns. D. Questioning the client about the frequency of falls is crucial, as it may indicate underlying health issues that could be contributing to weight loss, decreased energy, and potential mobility challenges.
