Pharmacy Technician Certification Board Practice Exam Practice Question
A pharmacy technician needs to measure 30 mL of mineral oil to fill a compounded prescription. Which of the following would most accurately measure the desired volume?
Correct Answer: D
Rationale: Measuring 30 mL of mineral oil requires precision, making the graduated cylinder the best choice. It is specifically designed for accurate volume measurement, with clear markings.
A glass beaker, while useful for mixing, lacks the precision needed for exact measurements, often leading to inaccuracies. A dosing spoon is typically used for smaller volumes and is not suitable for measuring 30 mL accurately. A prescription bottle is intended for storage rather than measurement, making it unreliable for precise dosing. Thus, the graduated cylinder is the most appropriate tool for this task.
