A nurse assesses a client's radial pulse to be irregular. Which action will the nurse take next?

Choice A reason: Counting the carotid pulse for one minute is not appropriate because the carotid pulse is not used for detailed rhythm assessment. It is mainly used to assess circulation in emergencies. Choice B reason: Counting the femoral pulse for one minute is not appropriate either. The femoral pulse is used to assess circulation in the lower extremities, not cardiac rhythm irregularities. Choice C reason: Using a doppler to count the apical pulse is unnecessary unless pulses are very faint or difficult to palpate. In this case, the nurse can directly auscultate the apical pulse without additional equipment. Choice D reason: Counting the apical pulse for one minute is the correct action. The apical pulse provides the most accurate assessment of heart rate and rhythm, especially when the radial pulse is irregular. This ensures proper evaluation of cardiac function.
