In asystole, which of the following is a key management step?

• A. Continue high-quality CPR and epinephrine administration; identify reversible causes.
• B. Immediately administer defibrillation.
• C. Administer only defibrillation attempts since no shockable rhythm.
• D. Terminate resuscitation after 1 minute.

Answer: (A)

In asystole, the priority is to maintain perfusion and search for reversible causes rather than delivering shocks. Asystole shows no electrical activity, so defibrillation won’t restore a rhythm. The best management is continuous high-quality CPR to preserve blood flow, along with timely epinephrine to improve coronary and cerebral perfusion during CPR. Administering epinephrine (typically 1 mg IV/IO every 3–5 minutes) helps support perfusion pressures while you work toward ROSC. At the same time, actively identify and treat reversible causes (the Hs and Ts) such as hypoxia, hypovolemia, electrolyte disturbances, acidosis, hypothermia, toxins, and cardiac or pulmonary causes like tamponade, tension pneumothorax, or thrombosis.

Defibrillation is not indicated in asystole because there is no shockable rhythm. Resuscitation should not be terminated after just a short trial; continue CPR and reassess according to protocol until ROSC occurs or termination criteria are met.
