Question

A client in ventricular fibrillation is about to be defibrillated. A nurse knows that to convert this rhythm effectively, the monophasic defibrillator machine should be set at which energy level (in joules, J) for the first delivery?

1.50 J
2.120 J
3.200 J
4.360 J

Answer 1

The initial energy level setting on a monophasic defibrillator for a patient in ventricular fibrillation should generally be 360 Joules. This is the standard energy level recommended for the first defibrillation attempt.

Step-by-step explanation:

The subject of the student's question concerns the appropriate energy level setting on a monophasic defibrillator for the first shock delivery to a patient in ventricular fibrillation. When using a monophasic defibrillator, the generally recommended initial energy setting for defibrillation is 360 Joules (J). This is because monophasic defibrillators deliver energy in one direction, thus requiring a higher energy shock compared to biphasic defibrillators. This high energy level is necessary to increase the chance of converting the ventricular fibrillation to a normal rhythm. The answer to the student's multiple-choice question would be option 4, which signifies 360 J. Remember that the practice guidelines could vary depending on the specific protocol and updates from the American Heart Association or equivalent bodies in other regions. It is vital to keep abreast of the latest CPR and Advanced Cardiovascular Life Support (ACLS) guidelines.
