While completing an admission assessment, the nurse is unable to palpate the client's left dorsalis pedis (DP) pulse. Which intervention is most important for the nurse to implement?

A. Reviewing the client's history for vascular disease is important but not the immediate priority when a pulse cannot be palpated. B. Placing a mark where the pulse is auscultated may be helpful for future assessments but is not useful if the pulse is not initially detected. C. Assessing capillary refill is a good way to check peripheral perfusion, but it doesn't directly address the absence of the pulse. D. Using a Doppler to assess an audible DP pulse is the most important step. The Doppler can detect pulses that are not palpable, helping to determine whether the issue is due to a weak pulse or a more serious circulatory problem.
