A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin) as an anticoagulant. What should the nurse include in the client's education about warfarin therapy?

A. Measuring the client's blood pressure is an important assessment but is not the immediate priority when preparing to administer enoxaparin.
B. Assessing the client's platelet count is critical before administering enoxaparin, especially because low molecular weight heparins can lead to heparin-induced thrombocytopenia (HIT). Monitoring platelet levels helps to ensure the client's safety and prevent complications.
C. Ensuring the client has an indwelling urinary catheter is not necessary for the administration of enoxaparin and does not relate to its safety or efficacy.
D. Obtaining the client's weight is relevant for dosing but is secondary to assessing the platelet count, particularly in light of the risk of HIT.

A) This choice is incorrect because while relieving leg pain and swelling is an important aspect of DVT treatment, the primary goal is to prevent the clot from dislodging and causing a pulmonary embolism or other complications.

B) This choice is correct. The primary goal of DVT treatment is to prevent the clot from dislodging and traveling to the lungs, where it can cause a potentially life-threatening pulmonary embolism. Anticoagulant therapy and other interventions are used to stabilize the clot and prevent its migration.

C) This choice is incorrect because eliminating the risk factors for DVT is not the primary goal of treatment for a client who already has DVT. Preventing clot progression and complications take precedence over addressing risk factors at this stage.

D) This choice is incorrect because while administering anticoagulant therapy is a common treatment for DVT, it is a specific intervention rather than the primary goal. Anticoagulants help prevent the clot from growing and reduce the risk of embolism.
