The nurse is unable to palpate the dorsalis pedis pulse on an older adult client. What would be most appropriate for the nurse to do next?

A. Auscultating the area may not provide accurate information about the pulse if it is not palpable, though it can be part of the assessment if Doppler is unavailable. B. Using Doppler ultrasonography is the most appropriate next step to accurately assess the pulse if it is not palpable, especially in older adults where pulses may be difficult to detect. C. Asking another nurse to assess the pulse may not address the underlying issue of why the pulse is not palpable and does not provide additional information. D. Documenting the absence of the dorsalis pedis pulse without further investigation could be premature, as Doppler ultrasonography should be used to confirm its absence.
