HESI A2 EXAM- Latest 2021/2022 (Updated) VERIFIED ANSWERS

1. A client on telemetry has a pattern of uncontrolled atrial fibrillation with a rapid ventricular response. Based on this finding, the nurse anticipates assisting the physician with which treatment? A. Administer lidocaine, 75 mg intravenous push. B. Perform synchronized cardioversion. C. Defibrillate the client as soon as possible. D. Administer atropine, 0.4 mg intravenous push. Rationale: With uncontrolled atrial fibrillation, the treatment of choice is synchronized cardioversion to convert the cardiac rhythm back to normal sinus rhythm. Option A is a medication used for ventricular dysrhythmias. Option C is not for a client with atrial fibrillation; it is reserved for clients with life-threatening dysrhythmias, such as ventricular fibrillation and unstable ventricular tachycardia. Option D is the drug of choice in symptomatic sinus bradycardia, not atrial fibrillation.
