A nurse is reviewing a cardiac rhythm strip of a client who has atrial flutter.
Which of the following findings should the nurse expect?
Progressively longer PR durations.
Undetectable P waves.
A saw-tooth pattern with an atrial rate of 250 to 400/min.
Absent PR intervals with a ventricular rate of 40 to 60/min.
The Correct Answer is C
A saw-tooth pattern with an atrial rate of 250 to 400/min is a characteristic finding on a cardiac rhythm strip of a client who has atrial flutter.
Choice A is incorrect because progressively longer PR durations are characteristic of a Mobitz type I second-degree AV block, not atrial flutter.
Choice B is incorrect because undetectable P waves are characteristic of atrial fibrillation, not atrial flutter.
Choice D is incorrect because absent PR intervals with a ventricular rate of 40 to 60/min are characteristic of third-degree AV block, not atrial flutter.
