Question

what is the next step of performing cpr on infants after you determine that an infant is not breathing?
shake, stroke, or tap the baby
deliver gentle rescue breaths to protect the babys lungs
give deep, strong compressions
immediately call 911

Explanation:

When performing CPR on an infant, after determining the infant is not breathing, the next step is to deliver gentle rescue breaths. This helps to provide oxygen to the infant's lungs. Shaking the baby is not appropriate as it can cause harm. Deep, strong compressions are part of CPR but after rescue breaths. Calling 911 is important but not the immediate next step after determining no breathing (in some protocols, if alone, you might start CPR first depending on local guidelines, but among these options, rescue breaths are the next step in the basic sequence of checking for response - if no response, check breathing - if no breathing, give rescue breaths).

Answer:

deliver gentle rescue breaths to protect the baby's lungs
