What crucial action should a nurse educate a patient about to reduce the risk of venous thromboembolism (VTE) after a coronary bypass graft (CABG)?

Early ambulation is a critical intervention for reducing the risk of venous thromboembolism (VTE) after a coronary bypass graft (CABG). When patients begin to move shortly after surgery, it promotes better circulation and helps prevent blood from pooling in the veins, which is a key factor in the development of clots. Movement enhances venous return and activates the muscular pump of the legs, significantly lowering the risk of stagnant blood flow that can lead to VTE.

While increased fluid intake and the use of compression stockings also play essential roles in VTE prevention, they are often considered supplemental strategies to the primary intervention of mobilization. Increased fluid intake helps maintain blood volume and circulation, but it does not directly stimulate venous return as ambulation does.

Prolonged bed rest, on the other hand, has been shown to increase the risk of VTE, as it can lead to stasis of blood flow. Therefore, prioritizing early ambulation is vital for enhancing patient recovery and minimizing the risks associated with surgical procedures such as CABG.
