A newly admitted client is started on heparin. The nurse recognizes heparin is effective for preventing new clot formation in which disorder?

Explanation:
The main concept is that heparin is an anticoagulant that prevents new clot formation and the growth of existing clots by accelerating antithrombin III, rather than dissolving clots. This makes it especially useful when the goal is to stop propagation of a thrombus in the venous system. Deep vein thrombosis is a condition where a clot forms in a deep vein, typically in the legs, and preventing new clots from forming or enlarging is crucial to reduce the risk of pulmonary embolism. While anticoagulation can be used in arterial settings like coronary thrombosis, MI, or stroke, the scenario described—starting heparin to prevent new clot formation—most directly aligns with preventing propagation in DVT.
