**Core Concept**
The American Academy of Pediatrics (AAP) recommends a specific compression-to-ventilation ratio for newborn resuscitation, which is crucial for effective management of neonatal asphyxia and successful initiation of breathing.

**Why the Correct Answer is Right**
The correct ratio for newborns is 3:1. This means that for every three compressions of the chest, one ventilation is performed. This ratio allows for adequate chest compression to maintain coronary and cerebral perfusion while also providing sufficient ventilation to help the newborn establish a patent airway and initiate spontaneous breathing. The use of this specific ratio is based on the understanding that newborns have a higher chest wall compliance and a more fragile cardiovascular system compared to adults, making them more susceptible to hypoxia and acidosis.

**Why Each Wrong Option is Incorrect**
**Option A:** This ratio is not recommended for newborns, as it would lead to inadequate ventilation and potentially cause further respiratory distress.
**Option B:** This ratio is actually used for infants and children, not newborns, and may not be suitable for the fragile cardiovascular system of a newborn.
**Option C:** This ratio is not commonly used in newborn resuscitation and may lead to inadequate chest compression, resulting in decreased coronary and cerebral perfusion.

**Clinical Pearl / High-Yield Fact**
Remember the "3:1" compression-to-ventilation ratio for newborn resuscitation, as it is a critical component of effective neonatal care and can significantly impact patient outcomes.

**Correct Answer:** D. 3:1
