Where do you check for a pulse on an infant?

To check for a pulse on an infant, the most appropriate location is the brachial artery. This artery is located inside the upper arm, and it is easily accessible for checking pulse in infants due to their smaller body size and underdeveloped circulatory system. The brachial pulse is reliable and is the preferred method for assessing circulatory status in this age group because it allows for accurate detection of a heartbeat.

The other locations, such as the carotid, radial, and temporal arteries, are not ideal for infants. The carotid artery, while a common site for pulse checks in adults, can be difficult to locate in infants due to their smaller necks. The radial artery, located at the wrist, is also harder to palpate in infants compared to older children and adults. Similarly, the temporal artery, found near the temples, is not a common or effective site for pulse checks in infants. Thus, the brachial artery is the best choice for assessing pulse in this context.
