Question

question 16 (mandatory) (1 point)
which of the following conditions is most commonly associated with a transient increase in serum iron levels due to increased release from damaged red blood cells?
a) hemolytic anemia
b) vitamin b12 deficency anemia
c) hereditary hemochromatosis
d) iron deficiency anemia
e) chronic kidney disease

Explanation:

• Hemolytic anemia involves the destruction of red blood cells (hemolysis). When red blood cells are damaged, iron (which is a component of hemoglobin in red blood cells) is released into the bloodstream, leading to a transient increase in serum iron levels.
• Vitamin B12 deficiency anemia is related to a lack of vitamin B12 which affects DNA synthesis in red - blood - cell precursors, not iron release from damaged red blood cells.
• Hereditary hemochromatosis is a genetic disorder of iron overload due to increased iron absorption, not due to red - blood - cell damage.
• Iron deficiency anemia is caused by a lack of iron (either due to insufficient intake, increased loss, etc.), not by iron release from damaged red blood cells.
• Chronic kidney disease can affect erythropoietin production (leading to anemia) and iron utilization (due to inflammation - related hepcidin changes), but not primarily by iron release from damaged red blood cells.

Answer:

A. Hemolytic anemia
