During the resuscitation of an adult, a rhythm check shows a flat trace consistent with asystole, having previously been pulseless electrical activity. High-quality compressions are ongoing and intravenous access is in place. What is the most appropriate immediate drug action?

Correct answer: D — Give intravenous adrenaline 1 mg promptly

Asystole is a non-shockable rhythm, so adrenaline 1 mg is given as soon as access is available and repeated every 3-5 minutes, with compressions continued and reversible causes sought. Defibrillation has no role in asystole, and atropine is not used in cardiac arrest. Amiodarone is reserved for shockable rhythms. Pearl: confirm true asystole by checking leads, connections and gain, since fine ventricular fibrillation can mimic a flat line.
