Description

This online course reviews basic mathematics related to the application of math concepts to the duties of the pharmacy technician. This course covers the systems of weight, measurement and temperature and the conversion from one system to the other. Emphasis is placed on the math skills needed to calculate doses, drug quantity or volume, intravenous flow rates and percentage concentrations and to learn the mechanics of proportions related to pharmaceutical dosing. The basics of retail pricing and accounting are introduced.

Learning outcomes

1. Demonstrate the relationship between units of measurement and use their correct abbreviations;
2. Calculate doses related to the administration of medication utilizing various systems of measurement;
3. Accurately read drug labels for amount of active ingredient contained in a measured amount of medication, and calculate the amount of medication to dispense for a specific dose;
4. Calculate the quantity of active ingredient in a percentage solution and solid mixture;
5. Calculate the amount of concentrate and diluent needed for a stock dilution compound;
6. Calculate age- and weight-specific drug doses or dose range when given recommended dose information;
7. Use a nomogram to estimate a patient’s body surface area (BSA) and use that BSA to calculate a patient-specific dose of medication;
8. Calculate the amount of ingredients needed for compounded mixtures using the alligation medial method;
9. Calculate the amount of active ingredient in a described mixture using the alligation alternate method;
10. Calculate aliquot portions for dilution of compounded products;
11. Calculate the least weighable quantity when given the specifications of the measuring device;
12. Calculate the rate and duration of parenteral administration of medications using both volume per hour and drops per minute;
13. Calculate business application needs such as percent markup, percent profit, overhead, profit, gross profit, percentage of AWP, capitation, days’ supply of inventory, and inventory maintenance ordering with minimums and maximums.
