Postoperative care to prevent thrombophlebitis after cesarean; which action should nurse encourage?

• A. Elevate her legs.
• B. Remain on bed rest.
• C. Ambulate frequently.
• D. Apply warm, moist packs to the legs.

Answer: (C)

Early ambulation after a cesarean section is the best way to prevent thrombophlebitis because movement promotes venous return from the legs and reduces venous stasis, a key factor in clot formation. When activity is limited, blood can pool in the deep veins, increasing the risk of a thrombus developing that could lead to thrombophlebitis or a pulmonary embolism. Getting up and walking, even for short distances as tolerated, helps keep the blood flowing and lowers this risk. Elevating the legs may reduce swelling but doesn’t address the main risk for clotting in the same way, and prolonged bed rest actually increases thrombosis risk. Warm, moist packs might provide comfort but do not prevent thrombophlebitis and could mask symptoms. Encourage ambulation as tolerated, with gradual increases in activity and other supportive measures as prescribed.
