Final answer:
The statement that accurately reflects successful teaching on the prescribed iron supplement for a pregnant woman with iron deficiency anemia is the one which mentions the need to eat foods high in fiber.
Step-by-step explanation:
The statement that indicates successful teaching after teaching a pregnant woman with iron deficiency anemia about her prescribed iron supplement is: "I need to eat foods high in fiber." This statement reflects an understanding of a potential side effect of iron supplements, which is constipation, and the need to counteract this by consuming a high-fiber diet to aid in digestion and bowel movements. Other aspects to consider include the fact that iron should not be taken with milk, as calcium can inhibit iron absorption. Instead, it is beneficial to take iron supplements with vitamin C, such as a glass of orange juice, to enhance absorption. Lastly, it is normal for stools to become black and tarry when taking iron supplements due to the unabsorbed iron; thus, it does not typically warrant a call to the doctor unless there are other concerning symptoms.
It's crucial for pregnant women to meet the recommended daily intake of 27 mg of iron to support their increased blood volume and the growth of the fetus. Rich sources of iron include red meat, shellfish, nuts, seeds, legumes, and fortified breakfast cereals. Women should also be aware that certain dietary components like phytic acid and oxalic acid can lower iron absorption.
