Final answer:
A hematological complication of mono can include aplastic anemia and other conditions such as splenic rupture, thrombocytopenia, leukopenia, and autoimmune hemolytic anemia.
Step-by-step explanation:
A hematological complication of infectious mononucleosis (mono) is aplastic anemia. This condition occurs when the bone marrow fails to produce adequate amounts of red and white blood cells, a situation that can be precipitated by repeated exposure to the Epstein-Barr virus (EBV) or Cytomegalovirus (CMV), which are known causes of mono.
Other potential hematological complications include splenic rupture due to spleen enlargement, hematological abnormalities like thrombocytopenia (low platelet count) or leukopenia (low white blood cell count), and autoimmune hemolytic anemia where the body's immune system mistakenly destroys its own red blood cells.
