After a bone marrow transplant, a patient is placed on a protocol of chemotherapy and radiation and has the potential for injury. Which nursing assessment should cause the nurse concern?

A. Increasing blood pressure: While it needs monitoring, it is less specific to transplant-specific complications than organ enlargement. B. Increased urine output: This is generally a positive sign of kidney perfusion unless it is excessive (diabetes insipidus), which is not common here. C. Decreasing bilirubin levels: This is a positive sign indicating the liver is functioning well and there is no excessive hemolysis. D. Increasing abdominal girth: This can be a sign of Veno-Occlusive Disease (VOD) of the liver, a serious complication of the high-dose chemo/radiation used before a bone marrow transplant. It indicates fluid buildup and liver congestion.
