A client has been diagnosed with thrombophlebitis.

(A) During pregnancy, the potential for thromboses increases owing to the increased levels of coagulation factors and a decrease in the breakdown of fibrin. (B) An inadequate production of platelets would result in thrombocytopenia with resulting signs and symptoms of bleeding such as petechiae, hematuria, or hematemesis. (C) A deficiency of folic acid during pregnancy produces a megaloblastic anemia. It is usually found in combination with iron deficiency. (D) This combination would result in bleeding disorders because more fibrin would be broken down and fewer clotting factors would be available.
