The nurse is caring for a 35-year-old multipara who delivered a full-term infant by cesarean delivery because of a breech presentation. The nurse recognizes that which of the following events would be the most important contribution to preventing thromboembolism
A. Increasing oral fluid intake.
B. Providing oxygen therapy.
C. Encouraging frequent ambulation.
D. Administering pain medications as neede
参考答案：C
解析：Encouraging frequent ambulation would be the most important contribution to the prevention of thromboembolism. Clotting factors and fibrinogen are increased in the immediate postpartum period. When the client is in this hypercoagulable state, the vessel damage that occurs with birth and immobility predisposes her to developing thromboembolism. Although increasing oral fluid intake also is important, encouraging frequent ambulation is most important. Providing oxygen therapy and administering pain medications don’t prevent thromboembolism formation.
