During pulse assessment, the RN asks the student to check the apical pulse after assessing the radial pulse. What is the rationale for this request?

• A. The client may have a dysrhythmia
• B. Radial pulse is easier to measure
• C. Apical pulse is more accurate at all times
• D. The apical pulse is not affected by tachycardia

Answer: (A)

The key idea is to detect a pulse deficit by comparing heart and peripheral pulses. If there’s a dysrhythmia, some heartbeats may not produce a palpable pulse at the radial artery. By listening to the apical pulse (actual heartbeats) and then comparing it with the radial pulse, you can uncover a difference in rate or rhythm that indicates an irregular heart rhythm. If the apical rate is higher than the radial rate, that deficit points to a potential dysrhythmia and signals the need for further assessment. This approach isn’t about radial being easier to measure or apical always being more accurate; it’s about identifying discrepancies between the heart’s activity and what reaches the periphery.
