A nurse prepares to defibrillate a client who is in ventricular fibrillation. Which intervention is appropriate for the nurse to perform prior to defibrillating this client?

Test the equipment by delivering a smaller shock at 50 J.

Administer 2 mg of intravenous epinephrine.

Make sure that the defibrillator is set to the synchronous mode.

Ensure that everyone is clear of contact with the client and the bed.

Answer and Explanation

The Correct Answer is D

A. Testing the equipment with a smaller shock is unnecessary when preparing to defibrillate in an emergency.

B. Epinephrine is used in cases of cardiac arrest with no pulse, particularly in asystole or pulseless electrical activity (PEA), not immediately before defibrillation in ventricular fibrillation.

C. Synchronous mode is used for cardioversion, not for defibrillation. Defibrillation should be delivered in unsynchronized mode.

D. Before delivering a shock, it is essential to ensure that everyone, including the nurse, is clear of the client and any conductive surfaces like the bed. This prevents injury from the electrical shock.

Correct Answer is A

Explanation

A. Sitting up and leaning forward helps improve lung expansion and ventilation, which is beneficial for clients with COPD.

C. The Trendelenburg position is not appropriate for improving ventilation in COPD patients.

D. While high-Fowler's may help in some situations, having the knees flexed can restrict the diaphragm and limit breathing capacity.

A. Digoxin B. Warfarin C. Furosemide D. Lisinopril

Correct Answer is B

Explanation

A. Digoxin is used to control the heart rate in atrial fibrillation but does not directly prevent the common complication of thromboembolism.

B. Warfarin is an anticoagulant used to prevent thromboembolic complications, such as stroke, which are common in atrial fibrillation due to the formation of clots in the atria.

C. Furosemide is a diuretic used to manage fluid retention, often in heart failure, but it does not prevent thromboembolism.

D. Lisinopril is an ACE inhibitor used to manage hypertension and heart failure, but it does not prevent thromboembolic complications.
