Explanation

The correct ratio for neonatal resuscitation (newborns) is 3 compressions to 1 breath.
This ratio is based on the high likelihood that cardiac arrest in a newborn is due to respiratory failure (asphyxia), making ventilation a critical component.
The goal is to achieve 90 compressions and 30 breaths per minute, which totals 120 events per minute, to optimize oxygenation and circulation.
Although the question uses the term 'infant', the absence of standard infant CPR ratios (30:2 or 15:2) in the options indicates the context is neonatal resuscitation.

Option A: A ratio of 1:5 is incorrect. It overemphasizes ventilation and does not align with any established CPR guideline for any age group.
Option B: A ratio of 5:1 is incorrect. While it prioritizes compressions, it does not match any current neonatal, pediatric, or adult CPR guidelines.
Option C: A ratio of 1:3 is incorrect. This would involve giving three breaths for every one compression, which would severely compromise blood flow and is the opposite of the correct neonatal protocol.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Neonatal Resuscitation Compression-Ventilation Ratio as background academic context rather than a clinical decision trigger.
Knowing the correct compression-to-ventilation ratio is critical for patient survival. Using the wrong ratio can lead to poor outcomes by failing to provide adequate oxygenation or circulation.
The distinction between neonatal resuscitation (NRP) and pediatric basic life support (BLS) is a key safety concept. NRP is for newborns at birth; BLS is for infants and children.
What if? If the patient was a 9-month-old infant found unresponsive and you had two rescuers, the correct ratio would be 15:2, not 3:1. The clinical context and patient's age are paramount.

How to Approach the Question

First, identify the core of the question: it asks for the compression-to-ventilation ratio during infant resuscitation.
Next, review the options provided: 1:5, 5:1, 1:3, and 3:1.
Recall the standard Basic Life Support (BLS) ratios for an infant: 30:2 (single rescuer) and 15:2 (two rescuers).
Notice that the standard infant ratios are not listed as options. This is a critical clue.
Consider special populations. The ratio 3:1 is specific to neonatal resuscitation (newborns).
Conclude that despite the use of the word 'infant', the question is testing knowledge of neonatal guidelines. Select 3:1 as the correct answer in this context.
