Q. A nurse is evaluating a client's electrocardiogram (ECG). Which ECG change can result from amitriptyline (Elavil) therapy?

A. Presence of U waves
B. Depressed ST segment
C. Widening QT interval
D. Prolonged PR interval




Correct Answer: C

Explanation: Amitriptyline therapy may cause a conduction delay, demonstrated by a widening QT interval on the ECG. U waves, a depressed ST segment, and a prolonged PR interval aren't typically induced by amitriptyline therapy.
