In the treatment and management of hemolytic anemia, what is the purpose of corticosteroids?
To stimulate the production of fetal hemoglobin.
To block the binding of autoantibodies to RBCs.
To surgically remove the spleen.
To improve tissue oxygenation.
The Correct Answer is B
Choice A rationale:
"To stimulate the production of fetal hemoglobin" is not the purpose of corticosteroids in the treatment and management of hemolytic anemia.
Corticosteroids are primarily used to suppress the immune response and reduce the destruction of red blood cells by autoantibodies.
Fetal hemoglobin is typically produced during fetal development and is not a target of corticosteroid therapy.
Choice B rationale:
The correct purpose of corticosteroids in hemolytic anemia is "To block the binding of autoantibodies to RBCs." Corticosteroids, such as prednisone, are often prescribed to reduce the autoimmune response that leads to the destruction of red blood cells.
By inhibiting the binding of autoantibodies to red blood cells, corticosteroids help to decrease hemolysis and improve anemia.
Choice C rationale:
"To surgically remove the spleen" is a treatment option in some cases of hemolytic anemia, particularly when the spleen is enlarged and contributing to the destruction of red blood cells.
However, it is not the primary purpose of corticosteroid therapy.
Choice D rationale:
"To improve tissue oxygenation" is not the primary purpose of corticosteroids in the treatment and management of hemolytic anemia.
While corticosteroids may indirectly improve tissue oxygenation by reducing hemolysis, their primary role is to modulate the autoimmune response and reduce the destruction of red blood cells.

Correct Answer is A
Explanation
"I have noticed that my urine has become very dark lately." Dark urine is a common clinical manifestation of hemolysis, as it indicates the presence of hemoglobin in the urine, known as hemoglobinuria.
This is a result of the breakdown of red blood cells and release of hemoglobin into the bloodstream.
Choice B rationale:
"My abdomen feels swollen and uncomfortable." Abdominal discomfort or swelling is not a specific clinical manifestation of hemolytic anemia.
It may be associated with conditions like splenomegaly but is not a characteristic sign of hemolysis.
Choice C rationale:
"I have been experiencing painful episodes in my bones." Painful episodes in the bones are not typically associated with hemolytic anemia.
Bone pain may be related to other conditions but is not a direct result of hemolysis.
Choice D rationale:
"I have been having severe headaches and chest pain." Severe headaches and chest pain are not specific clinical manifestations of hemolytic anemia.
These symptoms may have other causes and should be evaluated separately.
Correct Answer is C
Explanation
Choice A rationale:
A complete blood count (CBC) with differential can provide information about the overall red blood cell count and indices but may not confirm the presence of immune-mediated hemolysis.
Choice B rationale:
A peripheral blood smear can show abnormalities in the shape and structure of red blood cells but may not confirm the presence of immune-mediated hemolysis or identify the underlying cause.
Choice D rationale:
Serum bilirubin and haptoglobin levels can provide indirect evidence of hemolysis, but they do not confirm the presence of immune-mediated hemolysis or identify the underlying cause.
Choice C rationale:
The direct antiglobulin test (DAT), also known as the Coombs test, is used to detect the presence of antibodies or complement proteins on the surface of red blood cells.
A positive DAT result indicates immune-mediated hemolysis, confirming the suspicion raised by the clinical presentation of pallor, fatigue, and splenomegaly.
This test is crucial for diagnosing the specific type of immune-mediated hemolytic anemia and guiding further management.
