During advanced cardiac life support, a 58-year-old male is in ventricular fibrillation. After CPR and 3rd shock, what is the next immediate drug to be administered according to AHA 2020 guidelines?

Correct option is B

After the 3rd defibrillation attempt in VF/pulseless VT, adrenaline 1 mg IV is administered every 3–5 minutes. Amiodarone follows after persistent VF, but adrenaline is the first mandatory drug.
Explanation of options: (a) ✘ Amiodarone 300 mg is used after the 3rd shock along with adrenaline, but adrenaline comes first as per protocol. (b) ✔ Correct; adrenaline 1 mg IV is repeated every 3–5 minutes and improves coronary perfusion during CPR. (c) ✘ Atropine is indicated in bradyarrhythmias/asystole, not VF. (d) ✘ Lidocaine is only an alternative to amiodarone when amiodarone is unavailable.
