Simulated
The nurse notes a client in supraventricular tachycardia. The patient has a pulse and the cardiac monitor is at the bedside. The nurse understands electrical intervention is indicated. What button does the nurse push to ensure the electricity is delivered on the R wave? Refer to the picture.
Correct answer
D
Rationale
Synchronized cardioversion delivers a shock on the R wave to avoid the vulnerable T wave period, reducing the risk of inducing ventricular fibrillation. The SYNC button ensures this timing.
