The nurse is caring for a patient who converts from normal sinus rhythm at 72/min to atrial fibrillation with a ventricular response at 164/min
Blood pressure is 160/76. Respiratory rate is 20/min with normal chest expansion and clear lungs bilaterally. IV heparin and cardizem are given. The nurse understands that the goal is to:
A) Decrease SA node conduction
B) Control ventricular rate
C) Improve oxygenation
D) Maintain anticoagulation
Ans: B
Feedback: Treatment for atrial fibrillation is to terminate the rhythm or to control ventricular rate. A rapid ventricular response reduces the time for ventricular filling, resulting in a smaller stroke volume. Control of rhythm is the initial treatment of choice followed by anticoagulation with heparin and then coumadin.
