Final answer:
In a cardiac emergency for a patient with refractory ventricular fibrillation, the immediate next order is to continue with CPR and provide additional defibrillation if necessary. Additional shocks may be administered at appropriate intervals until the patient's heart rhythm stabilizes.
Step-by-step explanation:
In a cardiac emergency, when a patient with refractory ventricular fibrillation has just been administered a shock, the immediate next order would be to continue with cardiopulmonary resuscitation (CPR) and provide additional defibrillation if necessary.
CPR involves chest compressions to help maintain blood flow to vital organs, while defibrillation delivers an electrical shock to restore the heart's normal rhythm. Additional shocks may be administered at appropriate intervals until the patient's heart rhythm stabilizes.
