Last Updated on May 10, 2025

Pediatric Advanced Life Support PALS Chapter 3 Basic Life Support Practice Test 2025 Questions and Answers Quiz. According to the handbook, all PALS providers are assumed to be able to perform BLS appropriately. PALS providers must first be proficient in BLS. High-quality BLS is the foundation of PALS.

Basic Life Support (BLS) utilizes CPR and cardiac defibrillation when an Automated External Defibrillator (AED) is available. BLS is the life support method with limited access to advanced interventions such as medications and monitoring devices. Generally, BLS is performed until the emergency medical services (EMS) arrive to provide a higher level of care.

High-quality CPR is the foundation of BLS and PALS interventions in every setting. High-quality CPR gives the child or infant the best chance of survival by circulating to the heart, brain, and other organs until spontaneous circulation (ROSC) is restored.
