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 can help improve circulation, but it does not directly assist in locating the pedal pulses. This action is not the most immediate or effective response when pulses are not palpable. B. Using a Doppler ultrasonic stethoscope is the appropriate action to take when pulses are not palpable. The Doppler can detect blood flow in arteries that are difficult to palpate due to factors like edema, weak pulse, or poor circulation, making it a crucial tool in this situation. C. Notifying the healthcare provider is important if the nurse is unable to locate the pulses after using a Doppler, but the initial step should be to use the Doppler to assess the pulses before escalating the concern. D. Palpating pulse points with the legs dependent might enhance blood flow to the lower extremities, but it is not as reliable or immediate as using a Doppler to locate the pulses when they are not palpable.
