Final answer:
A low white blood cell (WBC) count is a potential complication of aplastic anemia. It increases the risk of infection.
Step-by-step explanation:
A potential complication of aplastic anemia would be a low white blood cell (WBC) count. In this case, the WBC count of 2,000/mm3 indicates a potential complication. A normal WBC count is typically between 4,500 and 11,000/mm3. A low WBC count can increase the risk of infection, as white blood cells play a crucial role in fighting off pathogens.
