Pharmacy Technician Certification Exam Practice Questions Practice Question
The pharmacy technician receives the following prescription for amoxicillin suspension for a pediatric patient: Give 375 mg amoxicillin suspension b.i.d. × 10 days The pharmacy stocks amoxicillin 250 mg/5 mL suspension. How many mL should the technician calculate for a single dose?
Correct Answer: B
Rationale: To determine the correct volume of amoxicillin suspension to dispense, first convert the prescribed dose of 375 mg into mL using the concentration provided (250 mg/5 mL).
1. Calculate the amount of suspension needed for 375 mg:
- 375 mg ÷ (250 mg/5 mL) = 375 mg × (5 mL/250 mg) = 7.5 mL.
Option A (5 mL) is incorrect as it represents a lower dose than required. Option C (10 mL) exceeds the prescribed dosage. Option D (15 mL) is also too high and not aligned with the calculated dose. Thus, 7.5 mL accurately reflects the necessary amount for a single dose.
