Question

which of the following methods should a pharmacy technician use to accurately measure volume when using a liquid for a non - sterile compounded product? use the liquid line at the top of the meniscus when measuring the volume. ensure the measuring device is no more than twice the size of the needed measured volume. use the device that is closest to the volume needing measured. measure the liquid line at a 45° angle.

Explanation:

To accurately measure liquid volume for a non - sterile compounded product:

• Option 1: Using the liquid line at the top of the meniscus is incorrect. The correct way is to use the bottom of the meniscus for measurement.
• Option 2: The measuring device being no more than twice the size of the needed volume is not the key principle for accurate measurement. The main idea is to use a device with a capacity as close as possible to the volume to be measured.
• Option 3: Using the device that is closest to the volume needing measured is the correct approach. This minimizes the error in measurement as smaller - capacity devices with appropriate graduations for the target volume will give a more accurate reading.
• Option 4: Measuring the liquid line at a 45° angle is incorrect. The standard practice is to view the meniscus at eye level (horizontal) to get an accurate reading.

Answer:

C. Use the device that is closest to the volume needing measured
