Final answer:
When taking the pulse of a child victim, you can use the brachial artery. Other arteries such as radial (at the wrist), carotid (in the neck), and femoral (in the thigh) can also be used to palpate a pulse.
Step-by-step explanation:
When taking the pulse of a child victim, you can often use the brachial artery. This artery is located in the upper arm and is commonly used especially for infants or young children. To measure the pulse at the brachial artery, you place the tips of your index and middle fingers on the inside of the upper arm, between the elbow and shoulder, pressing lightly until you feel the pulse.
Besides the brachial artery, a pulse can also be measured at the radial artery, which is found at the wrist. Furthermore, several other arteries such as the carotid in the neck or the femoral in the thigh can be used if necessary, and in an emergency situation, finding any palpable pulse can be appropriate.
