What can cause aplastic anemia?

• A. Increased red blood cell production
• B. Damaged bone marrow from chemical or radiation
• C. Excessive hydration
• D. Increased iron intake

Answer: (B)

Aplastic anemia is a condition characterized by the failure of the bone marrow to produce sufficient blood cells, including red blood cells, white blood cells, and platelets. One of the main causes of aplastic anemia is damage to the bone marrow, which can be induced by various factors, including exposure to certain chemicals, toxins, or radiation. When the bone marrow is damaged or fails to function properly, it cannot produce adequate amounts of blood cells, leading to symptoms such as fatigue, increased susceptibility to infections, and easy bruising or bleeding. Therefore, understanding the role of environmental factors, as well as the impact of certain medications or diseases that can harm the bone marrow, is essential in recognizing the etiology of aplastic anemia. The other options do not relate directly to the pathophysiology of aplastic anemia. Increased red blood cell production would be contrary to the condition, as it involves a decrease in cell production rather than an increase. Excessive hydration does not lead to anemia; in fact, it can sometimes dilute the blood but does not cause bone marrow failure. Lastly, while increased iron intake might address anemia caused by iron deficiency, it does not contribute to the development of aplastic anemia, which stems from bone marrow dysfunction.
