Final answer:
The nurse should prepare for synchronized cardioversion.
Step-by-step explanation:
The nurse should prepare for synchronized cardioversion.
In supraventricular tachycardia, the heart rate is excessively fast and may cause symptoms such as low blood pressure and rapid breathing. Synchronized cardioversion is a procedure that delivers an electric shock to the heart at a specific time during the cardiac cycle to restore normal rhythm. This intervention is needed in this case to correct the client's abnormal heart rate and improve blood pressure.
