Final answer:
The next medication to order would be amiodarone as the antiarrhythmic drug.
Step-by-step explanation:
If a patient is in refractory ventricular fibrillation (VFib) and high-quality CPR is in progress, the next medication to be ordered would be amiodarone as the antiarrhythmic drug.
Amiodarone is commonly used in cardiac arrest situations when VFib or pulseless ventricular tachycardia (VTach) persist after defibrillation and the administration of epinephrine. It helps stabilize the heart's electrical activity and improve the chances of restoring a normal sinus rhythm.
It is important to note that the specific medication to be ordered may depend on the protocols and guidelines of the specific healthcare facility or organization.
