Hello everybody, I was hoping someone could explain this question to me. Specially, "normal control?" I haven't heard of that before
The nurse should adjust a client's heparin dose according to a prescribed anticoagulation order based on maintaining which laboratory value at what therapeutic level for anticoagulant therapy?
A) Prothrombin time, 1.5 to 2.5 times the normal control.
B) Partial thromboplastin time, 1.5 to 2.5 times the normal control.
C) International Normalized Ratio, 2 to 3 seconds.
D) Thrombin clotting time, 10 to 15 seconds.
I choose D because it was the closest to Thrombin clotting time but the answer is B.
Rational: The nurse should adjust the heparin dose to maintain the client's partial thromboplastin time between 1.5 and 2.5 times the normal control. The prothrombin time and INR are used to maintain therapeutic levels of Warfarin, oral anticoagulation therapy. The thrombin clotting time is use to confirm DIC.
