What would a nurse most likely do to stop the bleeding quickly and effectively? apply a hemostatic drug directly on the cut so that clotting factors from the drug help the blood to clot apply clopidogrel directly on the cut so that platelet aggregation is inhibited and blood is able to come together in a clot administer a shot of a hemostatic drug in the arm so that the liver produces fewer clotting factors administer a shot of heparin deep into a vein in order to block clotting factor X and stop heavy blood flow to the foot
