Which equipment can measure fluid volume via syringe attachment?

The selection of transfer sets as the correct answer is based on their specific design and function in sterile compounding. Transfer sets are equipped with connectors and flow paths that allow for the transfer of liquid from one container to another while maintaining sterility. These sets often include a syringe attachment that enables the accurate measurement of fluid volume during the transfer process.

In sterile compounding, accurate measurement of fluid volumes is crucial for the preparation of medications. Transfer sets help ensure that the correct dosages are maintained and minimize the risk of contamination during transfer processes. This capability distinguishes them from the other options, which do not serve the purpose of measuring fluid volume in the same direct manner.

While a vented needle might aid in air equalization within a fluid container, it does not directly measure fluid volume. A sterile filter straw is typically used for aspirating and filtering solutions but is not designed for volume measurement. A closed system transfer device (CSTD) is intended to safely transfer hazardous drugs without exposure, but it does not primarily measure volume. Therefore, transfer sets are the best option for measuring fluid volume via syringe attachment.
