The nurse is collecting a nutritional history on a 28- year-old female client with iron-deficiency anemia and learns that the client likes to eat white chalk. When implementing a teaching plan, the nurse should explain that this practice:
A.
Will bind calcium and therefore interfere with its metabolism
B.
Will cause more premenstrual cramping
C.
Interferes with iron absorption because the iron precipitates as an insoluble substance
D.
Causes competition at iron-receptor sites between iron and vitamin B1
(A) Eating chalk is not related to calcium and its absorption. (B) Poor nutritional habits may result in increased discomfort during premenstrual days, but this is not a primary reason for the client to stop eating chalk. Premenstrual discomfort has not been mentioned. (C) Iron is rendered insoluble and is excreted through the gastrointestinal tract. (D) There is no competition between the two nutrients.
