Module 2: Methods of Medication Dosage Calculation

    Fractional Equation

    Another method of medication dosage calculation is the "fractional equation" method. You can choose which method you prefer to use.

    Formula: (H / V) = (D / X)

    Order : Morphine Sulfate 8 mg, IV, q 3h prn pain

    H: the dosage written on the medication label or in other words, what is "on hand."

    V: the "vehicle" or the form in which the medication is prepared (e.g. tablet, capsule, liquid)

    D: the medication dose ordered by the physician or nurse practitioner

    X: the "unknown" amount to be administered
