What is the most appropriate site for an EKG technician to take the pulse of an infant?

Radial artery
Brachial artery
Carotid artery
Femoral artery

The correct answer is: Brachial artery

Taking the pulse of an infant is typically most appropriately done at the brachial artery. This is due to the anatomical positioning and accessibility of the brachial artery in infants, which runs along the inside of the upper arm. This site allows for a reliable assessment of heart rate without the need for more invasive methods or causing discomfort to the infant. In contrast, while the radial artery can be used for pulse checking in older children and adults, its smaller size and depth can make it difficult to locate in infants. The carotid artery, located in the neck, is more challenging to access safely in infants and is generally not used as a routine pulse site in this age group. The femoral artery, found in the groin area, is another potential site but is also more invasive and less convenient compared to the brachial artery, particularly in emergency or routine assessments of heart rate in infants. Therefore, the brachial artery is the most appropriate and recommended site for taking the pulse of an infant.
