A client is admitted with complaints of lower extremity edema and occasional shortness of breath. Which electrocardiogram finding supports that the client is at risk for an alteration in perfusion?
A) P wave smooth and round
B) Absent U wave
C) PR interval 0.30 seconds
D) ST segment isoelectric
Answer: C
The PR interval is normally 0.12-0.20 seconds. Intervals greater than 0.20 seconds indicate a delay in conduction from the SA node to the ventricles. A P wave should be smooth and round. The ST segment should be isoelectric. The U wave is not normally seen.
