A 60-year-old woman received total body irradiation with a dose of 6 Gy. The radiation was followed by hair loss and a "hematopoietic syndrome". Bleeding tendency in this woman is most likely related to
A. anemia
B. leukopenia
C. thrombocytopenia
D. hypofibrinogenemia
E. reduced plasmin formation in the circulation
C
Radiation destroys and kills the precursors of the red blood cells, causing anemia; precursors of white blood cells, causing leukopenia; and megakaryocytes, the source of platelets, that leads to thrombocytopenia. Thrombocytopenia is the main cause of prolonged bleeding time and a generalized bleeding tendency in irradiated persons.
