Final answer:
The next dose for electrical therapy in a patient with ventricular fibrillation is another shock.
Step-by-step explanation:
The next dose for electrical therapy in a patient with unresponsive and in coarse ventricular fibrillation, after the initial shock, is another shock.
Ventricular fibrillation is a serious medical emergency that requires immediate intervention.
Defibrillation, which delivers a large charge to the heart, is the most common treatment for ventricular fibrillation.
The goal is to terminate the irregular heart rhythm and help the heart regain a normal sinus rhythm.
