AHA Pediatric Advanced Life Support (PALS) Practice Exam 2025 – The Comprehensive All-in-One Guide to Exam Success!

Rhythm checks in PALS are crucial for identifying whether a child in cardiac arrest is experiencing a shockable rhythm, such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). The rationale for this is that the immediate administration of defibrillation can be a life-saving intervention for these specific types of arrhythmias. By conducting rhythm checks at regular intervals, responders can determine the appropriate timing for delivering shocks, thereby enhancing the chances of restoring a normal cardiac rhythm and improving the patient's outcome.

The emphasis on evaluating specific rhythms during these checks underscores the importance of the rhythm in guiding further intervention strategies, including the continuation of CPR or the provision of medications based on the established cardiac status. For instance, if a non-shockable rhythm is identified, the focus would shift toward effective CPR and advanced airway management rather than defibrillation.

Other options, while relevant to cardiac care and resuscitation, do not align as directly with the specific goal of rhythm checks. The determination of whether CPR should be initiated precedes rhythm checks, as CPR should be initiated as soon as cardiac arrest is suspected. Assessing signs of recovery and taking a baseline heart rate are important but are not the primary objectives of rhythm checks during the active
