If a woman is instructed to take 0.8 mg/day of folic acid, how many stock tablets of 0.4 mg should she take daily?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

To determine the number of 0.4 mg folic acid tablets needed to achieve the prescribed daily dose of 0.8 mg, you can divide the total required dosage by the dosage per tablet. In this case, the total amount of folic acid needed is 0.8 mg. Each tablet contains 0.4 mg. When you divide 0.8 mg by 0.4 mg per tablet, you get: 0.8 mg ÷ 0.4 mg/tablet = 2 tablets. Therefore, the woman needs to take 2 tablets of the 0.4 mg folic acid daily to meet her requirement of 0.8 mg. This calculation ensures she achieves the correct dosage for optimal health, particularly important in pregnancy for fetal development and to prevent neural tube defects.
