A nurse prepares to defibrillate a client who is in ventricular fibrillation. Which intervention is appropriate for the nurse to perform prior to defibrillating this client?
Test the equipment by delivering a smaller shock at 50 J.
Administer 2 mg of intravenous epinephrine.
Make sure that the defibrillator is set to the synchronous mode.
Ensure that everyone is clear of contact with the client and the bed.
The Correct Answer is D
A. Testing the equipment with a smaller shock is unnecessary when preparing to defibrillate in an emergency.
B. Epinephrine is used in cases of cardiac arrest with no pulse, particularly in asystole or pulseless electrical activity (PEA), not immediately before defibrillation in ventricular fibrillation.
C. Synchronous mode is used for cardioversion, not for defibrillation. Defibrillation should be delivered in unsynchronized mode.
D. Before delivering a shock, it is essential to ensure that everyone, including the nurse, is clear of the client and any conductive surfaces like the bed. This prevents injury from the electrical shock.
