The nurse is aware that cryoablation therapy involves:
A) Peeling away the area of endocardium responsible for the dysrhythmia
B) Using electrical shocks directly to endocardium to eliminate the source of dysrhythmia
C) Using high-frequency sound waves to eliminate the source of dysrhythmia
D) Using a probe cooled to a temperature of -60°C (-76° F) to eliminate the source of dysrhythmia
Ans: D
Feedback: Cryoablation therapy involves using the cooled probe to create a small scar on the endocardium to eliminate the source of the dysrhythmias. Endocardium resection involves peeling away a specified area of the endocardium. Electrical ablation involves using shocks to eliminate the area causing the dysrhythmias. Radio frequency ablation uses high-frequency sound waves to destroy the area causing the dysrhythmias.
