The nurse is preparing to defibrillate a patient with ventricular fibrillation. The nurse should double-check the synchronizer switch because:
Explanation
• Defibrillators do not synchronize with an ECG rhythm with a P wave or with
• The defibrillator cannot deliver an immediate, untimed shock when the synchronizer is turned on. The nurse needs to turn the synchronizer off first.
• The synchronizer switch is turned on when cardioverting a patient's arrhythmia in synch with the ECG strip containing QRS complexes such as uncontrolled atrial fibrillation. Ventricular fibrillation does not contain a normal QRS complex.
