Which postoperative factor increases the risk of pulmonary embolism after cesarean section?

Which postoperative factor increases the risk of pulmonary embolism after cesarean section?

• A. Immobility due to surgery
• B. Regular ambulation after surgery
• C. Adequate hydration
• D. Exercise

Answer: (A)

Immobilization after surgery slows venous return in the legs, promoting blood stasis. In the cesarean postoperative period, the combination of pregnancy’s hypercoagulable state and surgical endothelial injury further encourages clot formation. A deep vein thrombus can then dislodge and travel to the lungs, causing a pulmonary embolism. So reduced movement directly increases risk. Regaining mobility, staying well hydrated, and exercising are protective because they improve venous return and reduce stasis, lowering embolism risk.
