Final answer:
The proper dosage of epinephrine for VF/pVT is 1 mg given intravenously or intraosseously, repeated every 3 to 5 minutes as per ACLS protocols.
Step-by-step explanation:
The proper dosing of epinephrine for ventricular fibrillation (VF) or pulseless ventricular tachycardia (pVT) is 1 mg IV/IO, repeated every 3 to 5 minutes. The use of epinephrine in this context is to attempt to restore a rhythm that can result in a perfusing heartbeat following cardiac arrest. It's important to follow established protocols and guidelines such as those provided by the Advanced Cardiovascular Life Support (ACLS) when administering medications in emergency situations like VF or pVT.
