The recommended CPR ratio for a child is 30 compressions to 2 rescue breaths. This ratio is endorsed by various resuscitation guidelines and is the standard approach used for cardiopulmonary resuscitation in children when provided by a single rescuer.

In a child, maintaining effective blood circulation through chest compressions is critical, and the correct ratio ensures that adequate compressions are prioritized to support the child's vital functions. The combination of 30 compressions followed by 2 rescue breaths allows for oxygenation as well as the mechanical aid to circulation, which is crucial in emergent scenarios like cardiac arrest.

While the other options may present different compression-to-breath ratios, they do not align with the current recommendations for CPR protocols in children, which emphasize the importance of frequent and effective compressions interspersed with manageable rescue breaths for optimal outcomes in resuscitation efforts.
