Question

Quizplus · Accepted Answer

The therapeutic PT time for a patient on warfarin (Coumadin) is typically 1.5 to 2 times the normal value. Given the laboratory's normal PT range is 9 to 11 seconds, a therapeutic PT would be approximately 13.5 to 22 seconds. Therefore, 17 seconds falls within this therapeutic range, indicating effective anticoagulation without excessive risk of bleeding.
