If a nurse observes a pulse deficit during a physical assessment, which pulses would be used to assess the pulse deficit?

• A. Radial and Apical
• B. Carotid and Femoral
• C. Brachial and Ulnar
• D. Dorsalis Pedis and Posterior Tibial

Answer: (A)

Pulse deficit occurs when the number of heartbeats differs from the number of peripheral pulses. To detect it, you compare a central pulse from the heart with a peripheral pulse. The standard way is to auscultate the apical pulse with a stethoscope at the apex of the heart and simultaneously palpate the radial pulse at the wrist, ideally counting for a full minute. If the apical rate is higher than the radial rate, a deficit exists, indicating that some heartbeats aren’t producing a palpable pulse in the periphery. This central-peripheral comparison is why apical and radial sites are used. Other pulses listed are in other sites and can be measured, but they don’t provide the essential heart-vs-periphery comparison needed to identify a pulse deficit.
