The student nurse reports to an experienced nurse finding a warm, red, tender area on the left calf of the client who is 48 hours postÔÇövaginal delivery. The nurse assesses the client and explains to the student that postpartum clients are at increased risk for thrombophlebitis due to which factors? Select all that apply.

During pregnancy, fibrinogen levels increase, and this increase continues to be present in the postpartum period. The increased levels can contribute to clot formation. There is not a shift of fluid from the interstitial to the vascular spaces in the postpartum period. Actual blood volume increases during pregnancy and is further increased immediately after delivery. This fluid volume is eventually lost through diuresis during the first postpartum week. Postpartum hormonal changes do occur, but they do not affect the vascular basement membranes. Elevation of the legs in stirrups during delivery leads to pooling of blood and vascular stasis. Dilation of the veins in the lower extremities occurs during pregnancy and increases the risk of venous stasis. Compression of the common iliac vein occurs during pregnancy due to an enlarging fetus and increases the risk of venous stasis.
