Cardiac Arrest Algorithms (CPR, ACLS) · NCLEX Exam

When should epinephrine be administered in the adult cardiac arrest algorithm?

  1. Only after at least three shocks in a shockable rhythm.
  2. Immediately after the first shock regardless of rhythm.
  3. After initial shocks if shockable, and early if non-shockable.
  4. Epinephrine is no longer recommended in cardiac arrest.
Show answer and explanation

Correct answer: After initial shocks if shockable, and early if non-shockable.

Epinephrine 1 mg IV/IO every 3-5 minutes is given after the initial defibrillation attempts in shockable rhythms (VF/pVT) and as soon as possible in non-shockable rhythms (asystole/PEA).
