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

SYNC

Answer and Explanation

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 ["83"]

Explanation

Step 1 is to use the formula for calculating the IV infusion rate: Infusion Rate (mL/hour) = Volume to be Infused (mL) ÷ Time for Infusion (hours)5.

So, Infusion Rate = 1000 mL ÷ 12 hours = 83.33 mL/hr.

Rounding to the nearest whole number gives 83 mL/hr.

So, the correct answer is 83 mL/hr, after calculating.

A. Take one tablet sublingually every 5 minutes x3 to relieve chest pain. B. Take this medication with 8 ounces of water. C. Take this medication after each meal and at bedtime. D. Take one tablet every 10 minutes x3 during an acute attack.

Correct Answer is A

Explanation

Choice A rationale: Nitroglycerin tablets are typically taken sublingually (under the tongue) at the onset of chest pain. If the pain is not relieved, a second tablet may be taken 5 minutes after the first. If the pain continues for another 5 minutes, a third tablet may be used123.

Choice B rationale: Nitroglycerin tablets are not typically taken with water. They are designed to dissolve under the tongue for quick absorption into the bloodstream1.

Choice C rationale: Nitroglycerin is not typically taken after each meal and at bedtime. It is used as needed to relieve chest pain1.

Choice D rationale: While nitroglycerin can be taken every 5 minutes up to three times during an acute angina attack, it is not typically recommended to take one tablet every 10 minutes1.

So, the correct answer is A, after analysing all choices.
