Certified Pharmacy Technician (CPhT)
Comprehensive Mock Examination
1. A patient presents a prescription for Lantus SoloStar 100 units/mL. The instructions are to
inject 25 units subcutaneously every evening. How many days will a 15 mL supply last?
A. 30 days
B. 45 days
C. 60 days
D. 90 days
Correct Answer: C
Explanation: To find the day supply, divide the total quantity by the daily dose: 15 mL
multiplied by 100 units/mL equals 1500 units; 1500 units divided by 25 units per day
equals 60 days. Accurate day supply calculations are critical for insurance billing and
ensuring patient adherence. Candidates should avoid confusing the total volume with the
total units available when performing insulin calculations.
2. Which DEA form is required for a pharmacy to report a significant loss or theft of controlled
substances?
A. DEA Form 222
B. DEA Form 41
C. DEA Form 106
,D. DEA Form 224

professionally certified?
A. Every 3 months
B. Every 6 months
C. Every 12 months
D. Every 2 years
Correct Answer: B
