What is the preferred method to check the pulse in an infant?

• A. Place two fingers on the carotid artery
• B. Place two fingers on the inside of the upper arm, midway between the infant's elbow and shoulder
• C. Palpate the radial pulse at the wrist
• D. Check for breathing instead of pulse

Answer: (B)

In infants, the best place to check for a pulse is along the brachial artery on the inside of the upper arm, midway between the elbow and the shoulder, using two fingers. This site is ideal because the artery is large enough to feel and lies close to the surface in a small child, making it easier to palpate accurately and quickly. Using two fingers helps you detect a pulse without applying excessive pressure, and avoid the thumb, which has its own pulse and can mislead you. The neck carotid artery is not preferred in infants because it’s harder to locate reliably and pressing there can be uncomfortable or risky. The wrist radial pulse is typically too small to feel reliably in an infant. Checking breathing is important for overall assessment, but it doesn’t replace checking the pulse when you’re evaluating circulation.
