A nurse is assessing a client's radial pulse and determines that the pulse is irregular. Which action should the nurse take?

A. Assessing the pedal pulses does not provide relevant information about the irregularity of the radial pulse. B. Assessing the apical pulse for a full minute is appropriate in this situation, as it provides a more accurate measurement of the heart rate and rhythm, especially when the radial pulse is irregular. C. Assessing the popliteal pulses with a Doppler device is not necessary and does not directly address the irregular radial pulse. D. While a pulse oximeter can provide information about oxygen saturation, it does not assess heart rate or rhythm.
