Which pairing accurately reflects fluid use for medications and iron absorption?

• A. Most medications should be swallowed with water; iron absorption is aided by orange juice or vitamin C.
• B. Most medications should be swallowed with juice; iron absorption is aided by water.
• C. Most medications should be swallowed with water; iron absorption is not affected by vitamin C.
• D. Most medications should be swallowed with milk; iron absorption is aided by orange juice.

Answer: (A)

Fluid choices influence how medications are absorbed and how iron is absorbed. Most medications are swallowed with water because it’s neutral and unlikely to interfere with dissolution or drug interactions. Using juice or milk can alter absorption for some medicines due to components like calcium or polyphenols, so water is the safest default. Iron absorption is enhanced by vitamin C, which keeps iron soluble and helps convert it to a form the body can absorb more efficiently. Orange juice provides vitamin C, so taking iron with orange juice promotes uptake. That’s why pairing medications with water and iron with a vitamin C–rich fluid is the best match.
