Chapter 52 Chapter Pharmacy Dosage Calculations Q&A (FPGEE) (1 OF 25) Sample Questions
1. A physician asks the pharmacist to compound codeine sulfate tablet triturates containing 10 mg of codeine. The patient needs 5-day supplies and may take
1-2 q4-6h PRN. How much codeine is needed to fill this prescription?
- A. 300 mg
- B. 400 mg
- C. 600 mg
- D. 1200 mg
- E. 2400 mg
Tips: In solving problems that involve range of doses, take the upper end of the dose multiplied by the greater dosing frequency.
12 x 10 x 5 = 600 mg
12 tab per day
For 5 days = 60 tab
Each tab contains 10 mg; so 10 mg x 60 tab = 600 mg
