Question

The nurse reviews the ECG strip, which indicates extended time between ventricular depolarization and repolarization. He checked the ventricular rate and rhythm again. To do that, the nurse would have to check which of the following?

1) PP interval
2) QT interval
3) RR interval

Answer 1

To assess for extended time between ventricular depolarization and repolarization on the ECG strip, the nurse would need to check the QT interval.

Step-by-step explanation:

The nurse would have to check the QT interval to assess the extended time between ventricular depolarization and repolarization on the ECG strip. The QT interval represents the time it takes for the ventricles to depolarize and then repolarize, and any prolongation of this interval can indicate abnormalities in ventricular electrical activity.
