Answer:
D. Resume high-quality chest compressions
Step-by-step explanation:
After a third shock has been administered and the patient remains in refractory ventricular fibrillation, chest compressions should be resumed since it is important to ensure that the patient receives adequate perfusion. Amiodarone and atropine can be options during this sequence of resuscitation effort, though are not necessarily the first steps to be taken. Checking the carotid pulse is not a recommended next action.
