A nurse must closely monitor which laboratory value for a client on heparin therapy for DVT?

The most critical laboratory value to monitor for a client on heparin therapy for deep vein thrombosis (DVT) is the activated partial thromboplastin time (aPTT). Heparin is an anticoagulant that works by inhibiting various factors in the intrinsic pathway of the coagulation cascade, which affects the aPTT. This test specifically assesses the effectiveness of heparin and helps ensure that the client remains within a safe therapeutic range to prevent clotting too much or experiencing complications such as bleeding. Monitoring the aPTT is essential because it provides real-time information on the anticoagulant effect of heparin. Generally, the aPTT should be maintained at a specific target range depending on the reason for anticoagulation therapy. This allows for the adjustment of heparin dosage based on the results, helping to minimize the risk of adverse effects associated with improper heparin use. Monitoring other values, like platelet count, are also important in the context of heparin therapy to assess the risk of heparin-induced thrombocytopenia (HIT), and while clotting time and bleeding time are relevant in broader contexts of coagulation status, aPTT is the key indicator for continuous heparin therapy
