A client's telemetry monitor indicates ventricular fibrillation (VF). Which action should the nurse implement immediately?
Defibrillate with one shock.
Prepare for external pacing.
Administer atropine IV.
Give a dose of amiodarone IV.
The Correct Answer is A
A. Defibrillation is the immediate treatment of choice for ventricular fibrillation to restore a normal heart rhythm. It delivers an electric shock to the heart, which can stop the abnormal rhythm and allow the heart to resume its normal rhythm.
B. External pacing is not effective for ventricular fibrillation as it requires an organized electrical activity to pace.
C. Atropine is used for bradycardia, not ventricular fibrillation.
D. Amiodarone is used to stabilize the heart rhythm after defibrillation but is not the immediate treatment for VF.
