Final answer:
The correct statement about blood disorders is that A. ferrous sulfate can treat iron deficiency. Ferrous sulfate, ferrous fumarate, and ferrous gluconate are effective treatments for iron deficiency anemia, and non-drug products can decrease iron absorption.
Step-by-step explanation:
The true statement about blood disorders related to iron deficiency is that ferrous sulfate is an example of an iron product that can treat iron deficiency. Various preparations such as ferrous sulfate, ferrous fumarate, and ferrous gluconate are commonly used in oral iron therapy to address anemia caused by iron deficiency. Non-heme iron absorption is generally less efficient than heme iron absorption, but oral iron supplements, including ferrous sulfate and ferrous gluconate, can effectively treat iron deficiency anemia. It's also important to note that non-drug products, such as certain foods and calcium, can bind to iron and decrease its absorption. Vitamin B 12, on the other hand, is not used to elevate iron levels in the body but rather to address pernicious anemia and facilitate DNA synthesis, which is critical for new cell production, including erythrocytes.
Among the given options, the correct statement about blood disorders is: C. Non-drug products can bind to iron to decrease iron absorption. Iron deficiency is a common form of anemia, and there are non-drug products that can bind to iron, such as tea and calcium-rich foods. These products can decrease the absorption of iron in the body, which can contribute to iron deficiency. It is important to be mindful of these interactions when trying to manage iron deficiency.
