In treating polymorphic ventricular tachycardia, what is the appropriate action if defibrillation is required?

In the treatment of polymorphic ventricular tachycardia, the appropriate action when defibrillation is indicated involves delivering a high-energy shock to restore a normal heart rhythm. The use of defibrillation at the specified joule settings (100, 200, 300, or 360) is essential because it ensures that sufficient energy is provided to effectively terminate the potentially life-threatening arrhythmia. The exact joule setting utilized may depend on specific protocols and the equipment available, but clinicians generally use higher energy doses for defibrillation in cases of unsynchronized shocks, such as confirming polymorphic ventricular tachycardia.

Other listed options do not directly address the immediate need for defibrillation in this scenario. Adenosine is useful for certain types of tachycardias but is not effective for polymorphic ventricular tachycardia, especially if the rhythm is not stable. Increasing IV fluid rates is relevant in certain clinical situations but does not directly manage the acuteness of polymorphic ventricular tachycardia. Additionally, synchronized cardioversion is more appropriate for stable tachycardias, where the patient's condition allows for potentially more controlled intervention. In polymorphic ventricular tachycardia, especially if it is unstable, immediate def
