Chapter 35: Dysrhythmias | Questions, Answers and Rationales A patient admitted with syncope has continuous ECG monitoring. An examination of the rhythm strip reveals the following: atrial rate 74 beats/min and regular; ventricular rate 62 beats/min and irregular; P wave normal shape; PR interval lengthens progressively until a P wave is not conducted; QRS normal shape. The priority nursing intervention would be to a. give epinephrine 1 mg IV push. b. prepare for synchronized cardioversion. c...
