Following two defibrillation shocks, the client's electrocardiogram (ECG) continues to indicate ventricular fibrillation (VF). Which intervention should the nurse implement next?

Resume CPR immediately.

Obtain an arterial blood gas sample.

Perform the third defibrillation shock.

Administer an IV bolus of epinephrine.

Answer and Explanation

The Correct Answer is C

Choice A: CPR is important but should be performed in conjunction with defibrillation. Since two defibrillation shocks have already been administered, the next step should be another shock.

Choice B : Obtaining an arterial blood gas sample is not the immediate priority when the client is in ventricular fibrillation. Defibrillation should be continued.

Choice C: Performing the third defibrillation shock is the next appropriate step in the advanced cardiac life support (ACLS) algorithm for ventricular fibrillation.

Choice D: Administering an IV bolus of epinephrine may be part of the ACLS protocol, but it is typically administered after defibrillation attempts.
