The nurse understands that in a third-degree AV block:

a. every P wave is conducted to the ventricles.
b. some P waves are conducted to the ventricles.
c. none of the P waves are conducted to the ventricles.
d. the PR interval is prolonged.


C
In first-degree AV block, a P wave precedes every QRS complex, which is followed by a T wave indicating complete conduction. It is represented on the ECG as a prolonged PR interval. Second-degree heart block refers to AV conduction that is intermittently blocked. Therefore, some P waves are conducted and some are not. Third-degree block is often called complete heart block because no atrial impulses are conducted through the AV node to the ventricles.
