Answer to Question 1

ANS: C
Chronic blood loss (bleeding ulcer, other gastrointestinal bleeding, urinary tract bleeding) eventually leads to iron deficiency. If iron deficiency develops in these individuals, then it requires a work-up by their physician to determine the source of bleeding; it can be occult.

Answer to Question 2

ANS: D
Lack of accessible iron results in ACI, as well as iron deficiency. In iron deficiency, iron stores are depleted. In ACI, iron stores are plentiful but the iron is cannot be mobilized for use in developing red cells.
