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.

Correct Answer is C
Explanation
Choice A rationale: Nitroglycerin tablets are not typically taken with water. They are designed to dissolve under the tongue for quick absorption into the bloodstream6789.
Choice B rationale: It is not necessary to go to the hospital to take the medication. The medication can be taken at the onset of chest pain6789.
Choice C rationale: This is the correct instruction. At the onset of chest pain, the patient should lie or sit down and place one tablet under the tongue6789.
Choice D rationale: If one tablet does not relieve the pain in 5 minutes, a second tablet may be taken. If the pain continues for another 5 minutes, a third tablet may be used. If the patient still has chest pain after a total of 3 tablets, they should seek immediate medical attention6789.
So, the correct answer is C, after analysing all choices
