Question 1 of 5

A nurse is caring for a client who has a new prescription for warfarin. The nurse should use the results of which of the following diagnostic tests to monitor the effect of this therapy?

Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). PT is used to monitor the effect of warfarin therapy because warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors, including prothrombin. Monitoring PT helps assess the anticoagulant effect of warfarin. Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin. White blood cell count (WB
C) and platelet count are not directly related to monitoring warfarin therapy.
