The nurse reviews the results of which of the following tests used for monitoring therapy with oral anticoagulants?

Question

Quizplus · Accepted Answer

The tests used for monitoring therapy with oral anticoagulants are prothrombin time (PT) and international normalized ratio (INR). PT measures the activity of the extrinsic pathway of the coagulation cascade, while INR is a standardized calculation of the PT that takes into account the variability in reagents used and provides a consistent measure of anticoagulation. Option A is incorrect because activated partial thromboplastin time (aPTT) is used to monitor therapy with unfractionated heparin. Option B is incorrect because partial thromboplastin time (PTT) is also used to monitor therapy with unfractionated heparin. Option D is incorrect because activated clotting time (ACT) is also used to monitor therapy with unfractionated heparin in certain situations.
