During a staff development conference on vitamins and minerals, which statement would require follow-up?

• A. Vitamin B6 supplements are given to help prevent macular degeneration
• B. Vitamin C should never be given with iron therapy
• C. Lead exposure can be prevented by vitamin A
• D. Vitamin D and calcium are unrelated to bone health

Answer: (C)

The main idea being tested is recognizing statements about vitamins and minerals that would require follow-up because they are inaccurate or could lead to unsafe practice. The statement that lead exposure can be prevented by vitamin A is the one that would need follow-up because it is not true. Lead exposure is prevented by reducing or eliminating the sources of lead and by applying appropriate public health and safety measures; vitamin A has no proven role in preventing lead exposure. In practice, misinformation like this needs correction to ensure safe care and accurate guidance. For context, vitamin C does not need to be avoided with iron therapy; in fact, vitamin C can increase iron absorption, so the claim that they should never be given together is incorrect and would require clarification. Likewise, vitamin D and calcium are both important for bone health, with vitamin D aiding calcium absorption, so saying they are unrelated is inaccurate and would also warrant follow-up. The statement about vitamin B6 and macular degeneration is less clearly supported by standard prevention guidelines, so it would also merit review, but the clearest safety issue to address first is correcting the lead exposure claim.
