Which pulse is used for infant circulation assessment?

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

Answer: (C)

In infants, rapid assessment of circulation is done by palpating the brachial pulse. The brachial artery runs along the inner arm and is easy to locate in a tiny infant, making it the most practical site for quickly gauging heart output and perfusion during routine checks or emergencies. The carotid pulse is not ideal in infants because it’s deeper and harder to feel reliably in tiny patients, and pressing it can be uncomfortable or less safe. The radial pulse is often too faint or difficult to palpate in young infants, and while the femoral pulse can be used, the brachial site offers quicker and more accessible assessment in an infant who is typically lying on their back with the arm readily exposed. Thus, the brachial pulse is the best choice for infant circulation assessment.
