A pregnant patient complains that the iron she is taking makes her constipated. The patient asks the nurse, "Why can't I just supplement the iron solely through my diet?" The nurse's best re-sponse is
a. "Only 10% of dietary iron is absorbed by the body."
b. "Only 25% of dietary iron is absorbed by the body."
c. "You can increase iron significantly through diet; eat bananas and citrus fruits."
d. "Drink a glass of milk daily with a half dose of iron, because it will enhance ab-sorption."
A

Milk greatly reduces the absorption of iron. Also, the patient should not reduce the dose without the prescriber's order.
