Question

24. A nurse is reviewing a cardiac rhythm strip of a client who has atrial flutter. Which of the following findings should the nurse expect?

a) progressively longer PR durations

b) undetectable p waves

c) absent PR intervals with ventricle rate of 40 to 60 / minutes

d) sawtooth pattern with atrial rate of 252 400 / minutes

Answer 1

Answer d

A sawtooth pattern with atrial rate of 252 -400 / minutes.

The atrial flutter orginates from the atria. That's why we suggest it as atrial flutter.In this condition the rhythm does not come from the sinus node. It is typically caused by a re-entry circuit that is contained within the atria. These re-entry circuits are very fast. They are repating 300 times in a minute. So we can see the P waves the look like the teeth of a saw and are called "sawtooth"

In this situation, there is a presence of 3 P waves to one QRS complex, then a sudden change to two P waves to one QRS complex. Or there can occour any combination of P waves to QRS complexes.Due to this results in the rhythm becoming irregular There are only two other rhythms that are commonly occurs during the atrial fibrillation they are irregularly irregular.
