One of the basic formulas used in pharmaceutical calculations allows you to determine how much of a medication you should administer based on the available sizes of medications. just because a patient needs a 25mg dose of medication does not means it will be available in a 25 mg tablet.
the main formula: O(ordered) / A(available)=Y (tablets required) This may also be written as: want/have or dose/have x quantity X units
It is absolutely critical the units are written along with all the steps in the calculation
Problem: Medication B in a dose of 150 mg is ordered for a patient. Medication B is available as 25 mg tablets. How many tablets would the nurse administer?
Homework Answers
As per the question, formula for the calculation of required tablet is:
Tablets required= ordered/available
The values for ordered and available are 150 mg and 25 mg.
By putting these values in the formula,
Tablets required = 150/25
Tablets required = 6
Thus, the required number of tablets for patient would be 6.
