What defines Hemolytic Anemia?

• A. Decreased production of RBCs
• B. RBCs destroyed faster than they can be produced
• C. Excessive calcium production
• D. Increase in RBC lifespan

Answer: (B)

Hemolytic anemia is characterized specifically by the destruction of red blood cells (RBCs) at a rate that exceeds the body's ability to produce new ones. This imbalance leads to a decrease in the number of functional RBCs in circulation, resulting in hemolytic anemia. Conditions that can contribute to the destruction of RBCs include autoimmune disorders, inherited conditions like sickle cell disease, and certain infections or chemicals that can cause the RBCs to break down prematurely.

While decreased production of RBCs is a factor in various types of anemia, it does not describe hemolytic anemia itself. Excessive calcium production is unrelated to the mechanism of RBC destruction. An increase in RBC lifespan also contrasts with the definition of hemolytic anemia, as the condition arises from reduced RBC survival due to their premature breakdown.

Thus, the defining feature of hemolytic anemia is indeed the accelerated destruction of red blood cells, making this the correct choice.
