Question
A nurse teaches a client newly prescribed ferrous sulfate 325 mg PO daily for iron deficiency anemia. Which set of instructions is most appropriate?
1Take on an empty stomach or with vitamin C (orange juice); expect dark stools; separate by ≥2 hours from calcium, antacids, and tetracyclines✓ Correct answer
2Take with high-fiber bran cereal
3Mix with antacid for better absorption
4Take with milk to soothe the stomach
Explanation
Correct (2): Iron absorption is best on an empty stomach with vitamin C (enhances ferrous form). Dark/black stools are expected and harmless. Separate from calcium, dairy, antacids, tetracyclines, fluoroquinolones, levothyroxine by ≥2 hours. (1,3,4) Reduce absorption.
In-depth explanation
Memory Tip Iron = "Empty + Vit C + dark stool". Liquid iron stains teeth → use straw. Constipation common — add fiber/water.
Clinical scenario
Scenario 28-year-old female with iron deficiency anemia starting ferrous sulfate 325 mg PO daily. Outpatient teaching.
Key concepts
Ferrous sulfate — PO iron salt; vitamin C enhances absorption.
