When giving a liquid iron supplement, what is the primary reason to use a straw?

• A. To speed absorption
• B. To prevent staining of teeth
• C. To prevent GI upset
• D. To ensure faster swallowing

Answer: (B)

To prevent staining of teeth. Liquid iron can leave dark stains on tooth enamel, especially on the front teeth, if it sits on them. Using a straw directs the iron toward the back of the mouth and minimizes contact with the front teeth, reducing the risk of staining. After taking the iron, rinsing the mouth with water or brushing later helps remove any residue. The other ideas don’t address staining: absorption occurs in the GI tract, and a straw doesn’t reliably prevent GI upset or make swallowing faster.
