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.
ANALYZE
SHOCK
ON
SYNC
The Correct Answer is D
Choice A rationale: The “ANALYZE” button is typically used to allow the defibrillator to analyze the heart rhythm. It would not ensure that the electricity is delivered on the R wave6.
Choice B rationale: The “SHOCK” button is used to deliver a shock during defibrillation or cardioversion. However, it does not specifically ensure that the shock is delivered on the R wave6.
Choice C rationale: The “ON” button is typically used to turn the device on or off. It does not control the timing of the electrical delivery6.
Choice D rationale: The “SYNC” button is used in synchronized cardioversion to match the delivery of the shock to the R wave of the ECG, which is the peak of the electrical wave during which the ventricular cells are depolarized6.
So, the correct answer is D, after analysing all choices.
