NCLEX Question of the Day
Review the question, check the correct answer, and read the rationale before tomorrow's prompt arrives.
A nurse is monitoring a patient receiving heparin therapy. Which laboratory test is most appropriate for assessing the anticoagulant effect of heparin?
-
Prothrombin Time (PT)/International Normalized Ratio (INR)
-
Bleeding time
-
Platelet count
-
Correct answer Activated Partial Thromboplastin Time (aPTT)
Rationale
Heparin primarily affects the intrinsic pathway of coagulation, and the aPTT test is used to monitor its anticoagulant effect. Regular monitoring with aPTT ensures the patient remains within the therapeutic range and reduces the risk of bleeding or clotting complications.
