Emergency Procedures Exam 1 Practice

The main idea here is how CPR technique changes between infants and adults, focusing on hand placement and compression depth. Infants require lighter, shallower compressions because their chest is small and more easily injured. For a single rescuer, the recommended method is to place two fingers on the chest and compress about 1.5 inches (about 4 cm) at a rate of 100–120 compressions per minute, allowing full chest recoil between pushes. This combination—two fingers with about 1.5 inches of travel—best fits the infant anatomy and safety guidelines.

That’s why the choice describing infants using two fingers with 1.5 inches of depth is the correct one. The other options mix in adult techniques or use hand positions that aren’t appropriate for an infant: two hands on an infant would risk over-compressing and injury; adults use two hands and deeper compressions (about 2 inches); and one hand with only 1 inch depth doesn’t match standard infant CPR.
