Final answer:
The statement by the woman with sickle-cell anemia regarding regular iron supplement intake might indicate a need for further instruction, as sickle-cell anemia is a genetic disorder, not caused by iron deficiency.
Step-by-step explanation:
In regards to prenatal care for a woman with sickle-cell anemia, the statement that would alert the nurse that she may need further instruction is: a) I've been taking my iron supplements regularly.
While iron supplementation is important for those with iron-deficiency anemia, sickle-cell anemia does not primarily result from iron deficiency. Instead, it is a genetic disease where the red blood cells are abnormally shaped, which can cause clogging in blood vessels and a host of other complications. Therefore, the consumption of iron supplements may not be beneficial and could even be harmful if it leads to iron overload.
Management strategies for sickle-cell anemia include stress management, avoiding strenuous physical activity, and consuming a diet rich in folic acid. Folic acid helps in the formation of new red blood cells, which is particularly important for those with sickle-cell disease because their red blood cells have a shorter lifespan than normal.
