When assessing an older adult client with a history of cardiovascular disease, dyspnea, and peripheral edema, which method is best for the nurse to use to assess the client's pulse rate?

A. Palpating the radial pulses might not detect irregularities in pulse rate or rhythm as effectively as auscultation at the apical site. B. Listening over the carotid artery may be useful in certain situations but is not the preferred method for assessing overall pulse rate. C. Feeling the dorsalis pedis and posterior tibialis pulses provides information about peripheral circulation but does not assess the overall heart rate. D. Auscultating the apical pulse is the most accurate method to assess the pulse rate, especially in clients with cardiovascular disease, as it provides direct measurement of heart activity.
