lb equals 16,000,000 kg

    • The prescription states QID, which means 4 tablet(s) per day.
    • Total duration of the treatment is 10 days.
    • Number of tablets administered during this period = 10 × 4 = 40;
    • Strength of one tablet = 250 mg.
    • Therefore, Total mg of antibiotic taken during this period = 40 × 250.
    250 mg = 40 × 250 mg
    400,000 unit x

    Therefore, x = 16,000,000
