A. “The iron supplement might cause my stools to be black.” Black, tarry-appearing stools are an expected side effect of oral iron due to unabsorbed iron. This is not a sign of bleeding unless accompanied by symptoms such as abdominal pain or bright red blood. B. “I should expect to have swelling in my feet.” Peripheral edema is not a side effect of iron therapy and is unrelated to iron-deficiency anemia. Edema would require new assessment for cardiac, renal, or medication-related causes. C. “I will take my iron supplement 1 hour before a meal.” Iron is best absorbed on an empty stomach (1 hr before meals or 2 hrs after). Vitamin C enhances absorption; calcium, antacids, and food decrease it. D. “I should increase green leafy vegetables in my diet.” Vegan diets carry a risk of iron deficiency because they exclude heme iron sources. Green leafy vegetables (spinach, kale, collards) are non-heme iron sources beneficial for anemia. E. “The iron supplement might cause ringing in my ears.” Tinnitus (ringing in ears) is not associated with iron supplements. It is more commonly linked to salicylate toxicity or ototoxic medications, not iron.
