A satisfactory radial pulse can be taken in children older than which age?

• A. Newborn
• B. 1 year
• C. Older than 2 years
• D. 5 years

Answer: (C)

The ability to obtain a reliable radial pulse depends on age and cooperation. In newborns and very young children, the radial artery is small and difficult to feel, and movement or distress can make counting inaccurate. For accurate heart rate assessment in infants, the apical pulse is usually used. As children grow, about two years old, their radial artery becomes larger and easier to palpate, and they can remain still long enough to count a steady pulse. That’s why a satisfactory radial pulse is typically obtainable in children older than about 2 years.
