Question

Quizplus · Accepted Answer

Changes in behaviour precede the appearance of anemia in cases of iron deficiency, indicating that iron deficiency affects the central nervous system before it affects erythropoiesis. Choice A is partially true in that pica, the practice of eating non-food items, may be a symptom of iron deficiency, but it does not directly enhance iron absorption. Choice C is incorrect as pica is actually a potential risk factor for iron deficiency, and delaying the onset of iron-induced behavioural changes is not a known effect of pica. Choice D is also incorrect as there is no evidence suggesting that adults are more resistant to iron-induced behavioural changes than children.
