What is characteristic of hemolytic anemia?

• A. Increased red blood cell production
• B. Destruction of RBCs from chemicals
• C. Inability to make blood cells
• D. High levels of white blood cells

Answer: (B)

Hemolytic anemia is characterized by the destruction of red blood cells (RBCs) at a rate that exceeds their production. This condition results in a lower number of circulating RBCs, which can lead to symptoms such as fatigue, pallor, and shortness of breath due to reduced oxygen-carrying capacity. The destruction of RBCs can be triggered by various factors, including autoimmune processes, certain infections, medications, or exposure to toxins, which highlights the relationship between hemolysis and the specific causes of hemolytic anemia. Increased red blood cell production would generally indicate a response to anemia rather than a characteristic of hemolytic anemia itself, where the opposite occurs. An inability to make blood cells pertains to aplastic anemia or other marrow-related disorders, which is different from the underlying mechanisms of hemolytic anemia. High levels of white blood cells typically indicate an inflammatory response or infection and are not a defining characteristic of hemolytic anemia. Thus, the focus on the destruction of RBCs aligns directly with the primary pathology involved in hemolytic anemia.
