In the Helicobacter pylori regimen described, the antibiotic is given at 400 mg twice daily. What is the total daily dose of this antibiotic?

Explanation:
The key idea is that total daily dose equals the dose per administration multiplied by how many times it’s given in a day. If each dose is 400 mg and it’s taken twice daily, you multiply 400 mg by 2, giving 800 mg per day. This reflects the amount the patient would receive over a 24-hour period. The other numbers correspond to different dosing frequencies or single-dose totals, which don’t apply to twice-daily administration.
