Final answer:
When an AED advises a shock on a pulseless child, immediate defibrillation is the next step. Compressions should continue until the shock is administered and resumed afterward, with other interventions like intravenous access or intubation following later. The correct answer is option C .
Step-by-step explanation:
When faced with a scenario where a child is unresponsive, apneic, and pulseless with CPR already in progress, and an Automated External Defibrillator (AED) recommends a shock, the next step is crucial. Having attached the AED to the child and receiving a shock recommendation, the correct action is to attempt defibrillation.
The AED is an advanced medical device designed to analyze the patient's heart rhythm and determine if a shock is necessary to correct an arrhythmia such as ventricular fibrillation or ventricular tachycardia. Upon a 'shock' recommendation, it automatically adjusts the energy level of the shock appropriate for the patient. It is critical to follow the verbal and visual prompts from the AED, ensuring that everyone is clear of contact with the patient before administering the shock. In a situation as described, CPR should continue until the shock is delivered, and immediately resumed following the shock, as high-quality chest compressions are also vital. This should take precedence over other actions such as obtaining intravenous access or attempting an endotracheal intubation initially.
The focus should be on delivering the shock as quickly as possible to increase the chances of restoring the heart's normal rhythm. Per standard emergency procedure, further actions such as intravenous access or advanced airway management can be considered after the delivery of the shock and the continuation of chest compressions and rescue breaths, if trained personnel are available.
