Pediatric Advanced Life Support (PALS) Practice Test

In the scenario where a trauma patient undergoes rapid intubation and capnography tracing falls off after five breaths, the most appropriate next step in management is to consider that the endotracheal tube may not be in the correct position, possibly indicating esophageal intubation or dislodgment of the tube.

When capnography readings drop significantly or become undetectable, it suggests that carbon dioxide is not being effectively delivered from the lungs, which usually means that there is no adequate ventilation occurring. In this context, confirming tube placement is critical. Removing the endotracheal tube and reintubating allows for a re-assessment of airway management and ensures that ventilation is achieved properly.

Checking for bilateral breath sounds is important, but if capnography is already indicating a problem, addressing the potential underlying cause by reintubating is a more direct approach. Similarly, administering supplemental oxygen or starting chest compressions would not resolve the issue of inadequate ventilation due to incorrect tube placement. The primary concern here is to ensure that the airway is secured properly, making reintubation the priority for restoring effective ventilation and ensuring that capnography readings can return to normal levels.
