The patient is immobilized after undergoing hip replacement surgery.Which of the following would place the patient at risk for hemorrhage?

A) Thick,tenacious pulmonary secretions.
B) Low-molecular-weight heparin doses to prevent DVT.
C) Sequential compression devices wrapped around the legs to prevent DVT formation.
D) Elastic stockings (thromboembolic disease [TED] hose) to promote venous return.

Heparin and low-molecular-weight heparin are the most widely used drugs in the prophylaxis of DVT.Because bleeding is a potential side effect of these medications,the nurse must assess the patient continually for signs of bleeding.Pulmonary secretions that become thick and tenacious are difficult to remove and are a sign of inadequate hydration,but not of bleeding.Sequential compression devices consist of sleeves or stockings made of fabric or plastic that are wrapped around the leg and are secured with Velcro.They decrease venous stasis by increasing venous return through the deep veins of the legs.They do not usually cause bleeding.Elastic stockings also aid in maintaining external pressure on the muscles of the lower extremities and in promoting venous return,and they also do not usually cause bleeding.
