مريض لديه رجفان أذيني منذ ٥ أيام وغير معروف متى بدأ بالضبط، وحالته مستقرة. الطبيب يخطط لإرجاع النظم. ما الذي يتوقعه الممرض قبل الصدمة الاختيارية؟

A stable client has had AF for about 5 days with an uncertain onset. The physician plans rhythm control. What does the nurse expect before elective cardioversion?

1. Immediate cardioversion with no preparation because he is stable
2. Several weeks of anticoagulation or a TOE to exclude atrial clot
3. High-dose digoxin to restore rhythm
4. Stopping all medicines a week before

Answer: B) Several weeks of anticoagulation or a TOE to exclude atrial clot. If AF has lasted over 48 hours or its onset is unknown, an atrial clot may embolise once rhythm returns. So weeks of anticoagulation are given, or a transoesophageal echo excludes clot.
