ACTIVITY GUIDE 3 : DRUG DOSAGE PROBLEMS It is not possible to manufacture medications in all possible dosages that a doctor might order. The nurse may therefore find that the amount of a drug ordered differs from the amount on hand in a single tablet or in one ml. of solution. In that event, it is necessary to be able to calculate the amount of drug to be given from the size, strength, or concentration available. A. Dosage Problems: Setting up an equation involving simple proportion and solving it for the unknown amount to be given may solve dosage problems. The formula for setting up this proportion is: Q X H D D = desired dosage (what the doctor has ordered) H = dosage on hand (the dosage strength available) X = desired quantity (how many tablets or how much solution you will give to carry out the order) Q = quantity on hand (the amount or volume in which the dosage on hand is contained) *RULE : D and H must be in the same units of measurement; X and Q will also be in the same units of measurement.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
