Aplastic anemia is a disorder in which the bone marrow cells that develop into mature blood cells become damaged. The damaged bone marrow cells can lead to low numbers of red blood cells, white blood cells, and/or platelets. When the cause of aplastic anemia cannot be diagnosed, the cause is likely which of the following?
Radiation exposure
An autoimmune disorder
Chemotherapy drugs
Toxins
The Correct Answer is B
A. Radiation exposure: Radiation exposure can cause aplastic anemia, but if the cause is unknown, it is less likely to be due to a specific and identifiable event like radiation exposure.
B. An autoimmune disorder: When the cause of aplastic anemia cannot be diagnosed, it is often attributed to an autoimmune disorder where the body attacks its own bone marrow cells.
C. Chemotherapy drugs: Chemotherapy drugs can cause aplastic anemia, but this cause would typically be known based on the patient's medical history.
D. Toxins: Toxins can cause aplastic anemia, but like chemotherapy drugs and radiation, this cause would generally be identifiable.
