Sample item

Which supplement reduces neural tube defect risk when started before conception?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

D. Folic acid

Folic acid before conception and in early pregnancy reduces neural tube defect risk because neural tube closure occurs early in embryonic development.

Option by option

  • A. Vitamin K

    Vitamin K prevents neonatal bleeding but not neural tube defects.

  • B. Iron only

    Iron prevents iron deficiency rather than neural tube defects.

  • C. Vitamin C

    Vitamin C does not provide this established prevention.

  • D. Folic acid (correct)

    Correct: folate supports early neural tube closure.
