To assess circulation on an infant, you would use their

• A. Brachial pulse
• B. Carotid pulse
• C. Radial pulse
• D. Femoral pulse

Answer: (A)

In infants, the brachial pulse is used to assess circulation because the brachial artery runs just beneath the skin on the inside of the upper arm, making it easy to locate and feel a pulse in a small child. This pulse provides a reliable signal of perfusion during quick assessments and CPR checks. The radial pulse is often too difficult to feel in infants due to their small vessels, the carotid pulse is more suited to older patients and can be less reliable in infants, and the femoral pulse, while usable, is less convenient for rapid checks. So, checking the brachial pulse gives the clearest, most practical indication of circulation in an infant.
