A patient has decrease mobility in all joints.Because of the lack of mobility,the nurse expects the health care provider to order what medication to prevent venous thromboembolisms that will reduce the side effect of hemorrhage?

A) Oral anticoagulant
B) Aspirin
C) Low-molecular-weight heparin
D) Unfractionated heparin

Newer low-molecular-weight (LMW)heparins such as ardeparin and enoxaparin are being prescribed in place of older forms of unfractionated heparin.The LMW heparins have a more predictable anticoagulant effect.Low-molecular-weight heparin compared with unfractionated heparin reduces the occurrence of major hemorrhage as a side effect.
Heparin is an anticoagulant that suppresses clot formation.This therapy requires a health care provider's order.Aspirin and oral anticoagulants increase the risk for hemorrhage.
