    Calculation

    Order: Fluconazole (Diflucan) 5 mg/kg p.o. every day. The label on the bottle reads "50 mg/tablet." Calculate how many capsules you should administer for a child who weighs 44 pounds.

    tablets

    Explanation & Rationale

    To calculate the dose of fluconazole for a child who weighs 44 pounds, you need to convert the weight to kilograms and the dose to milligrams. One kilogram is equal to 2.2 pounds, so 44 pounds is 44 / 2.2 = 20 kilograms. The dose of fluconazole is 5 mg/kg, so 5 mg x 20 kg = 100 mg. The label on the bottle says that each tablet contains 50 mg of fluconazole, so you need to divide the dose by the tablet strength to get the number of tablets. 100 mg / 50 mg = 2 tablets. Therefore, you should administer two tablets of fluconazole once a day for this child.
