A nurse is checking the apical pulse of a client who is taking several cardiovascular medications. Which of the following actions should the nurse take?

A. The apical pulse should be counted for a full minute to detect irregularities, especially in clients taking cardiovascular medications such as digoxin or beta-blockers. B. A Doppler device is not needed unless the pulse is difficult to auscultate. C. While the diaphragm is used for high-pitched sounds, the critical action in this situation is ensuring an accurate full-minute count. D.
