Final answer:
The therapeutic goal of radiofrequency catheter ablation is the destruction of errant tissue to disrupt abnormal electrical pathways and restore normal rhythm for clients with cardiac dysrhythmias. Therefore, the correct option is C.
Step-by-step explanation:
The therapeutic goal of radiofrequency catheter ablation for a client with cardiac dysrhythmias is c) Destruction of errant tissue.
Radiofrequency catheter ablation is a procedure used to treat certain types of cardiac dysrhythmias, such as atrial fibrillation or ventricular tachycardia. During this procedure, a specialized catheter is used to deliver radiofrequency energy to the areas of the heart that are responsible for the abnormal electrical signals. The goal is to create small scars or lesions on the heart tissue, which disrupts the abnormal electrical pathways and restores normal rhythm.
