When epinephrine should be administered during resuscitation after shocks?

• A. Before any shocks
• B. After 1 shock
• C. After 2 shocks have been delivered, 1 mg IV/IO every 3 to 5 minutes
• D. Never

Answer: (C)

Epinephrine is used during CPR to boost coronary and cerebral perfusion pressures, helping to improve the chance of return of spontaneous circulation. In resuscitation for a shockable rhythm, the timing is to add epinephrine after two shocks have been delivered, with 1 mg IV/IO given and then repeated every 3–5 minutes during ongoing CPR. This approach keeps defibrillation and chest compressions as the immediate priorities, while using vasopressor support to enhance perfusion during the CPR cycles that follow. It isn’t given before any shocks, because delivering a shock promptly is the first goal, and delaying shocks to give a vasopressor isn’t beneficial. It also isn’t withheld after two shocks, since the vasopressor helps sustain perfusion during continued attempts at ROSC.
