Explanation

The rate of 100 compressions and 20 ventilations per minute is a standard often used for pediatric CPR in examination contexts, reflecting a 5:1 ratio performed over 20 cycles in a minute.
This rate helps distinguish pediatric CPR from neonatal resuscitation, which uses a different ratio and rate.
The primary goal in all CPR is to maintain a chest compression rate of 100–120 per minute while providing adequate ventilation.
This specific rate (100:20) is less common in current AHA guidelines, which prioritize ratios per cycle (30:2 or 15:2), but it remains a plausible answer when presented as a per-minute total.

Option A: A compression rate of 60 per minute is too slow and does not meet the minimum recommended rate of 100-120/min for effective circulation.
Option B: This rate (90 compressions and 30 ventilations per minute) is based on a 3:1 ratio and is the standard for newborn resuscitation (NRP), not for pediatric CPR (PALS/BLS).
Option C: This ratio does not correspond to any established CPR guideline and would lead to excessive ventilation (hyperventilation), which can be harmful.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Pediatric CPR Compression-to-Ventilation Ratios as background academic context rather than a clinical decision trigger.
Nurses must be proficient in CPR and know the correct guidelines for different age groups, as using the wrong ratio can compromise patient outcomes.
The most common cause of cardiac arrest in children is respiratory failure, making effective ventilation alongside compressions particularly critical.
What if? If the child has an advanced airway (e.g., an endotracheal tube) in place, the protocol changes. Chest compressions become continuous at 100-120/min, and one breath is given every 2-3 seconds (20-30 breaths/min) without pausing compressions.

How to Approach the Question

First, identify the key components of the question: 'rate', 'chest compression', 'ventilation', and the specific patient population, 'children'.
Recall the fundamental principles of CPR, especially the target compression rate of 100-120 per minute.
Differentiate between guidelines for different age groups. The term 'children' in a medical context is distinct from 'newborns'.
Evaluate the given options. Recognize that 90 compressions : 30 ventilations is the specific rate for newborns (3:1 ratio). This allows you to eliminate it as the answer for 'children'.
Assess the remaining options against the target compression rate. 100 compressions : 20 ventilations aligns with a rate of 100/min and is a plausible per-minute total, often derived from older 5:1 ratio guidelines.
Select the answer that best fits the pediatric (non-newborn) context, even if it reflects a slightly different way of calculating rates than the most current cycle-based AHA guidelines.
