To prevent thrombophlebitis after a cesarean section, what should the nurse encourage the woman to do?

Encouraging frequent ambulation after a cesarean section is crucial in preventing thrombophlebitis, which is a condition characterized by inflammation of a vein due to a blood clot. Movement and ambulation help to stimulate blood circulation, reducing the risk of blood pooling in the veins of the legs. This is particularly important after surgery, when patients are at a higher risk for thromboembolic events due to factors such as decreased mobility and changes in blood coagulability.

While resting, maintaining leg elevation, and increasing fluid intake can be supportive measures, they do not directly address the primary concern of enhancing venous circulation. Ambulation encourages the contraction of muscles in the legs, which helps to propel blood flow back toward the heart, thus lowering the likelihood of clot formation and subsequent complications. Therefore, frequent ambulation is the most effective intervention to promote venous return and decrease the risk of developing thrombophlebitis after a cesarean section.
