While performing a physical assessment, the nurse is unable to palpate the client's pedal pulses. Which action should the nurse take?

A. Applying warm blankets to both feet may help improve circulation but is not the most effective method for locating pedal pulses. This approach does not immediately address the difficulty in palpation. B. Using a Doppler ultrasonic stethoscope is the appropriate action when pedal pulses are not palpable. The Doppler can detect blood flow in cases where pulses are weak or difficult to feel, making it a vital tool in this scenario. C. Notifying the healthcare provider is necessary if the Doppler fails to detect pulses, but the initial step should be to use the Doppler to assess the pulses before escalating the situation. D. Palpating pulse points with the legs dependent may assist in enhancing blood flow to the extremities, but it is less reliable than using a Doppler to detect the pulses when they are not palpable.
