What is used to prevent the release of aerosols, vapors, and droplets in sterile compounding?

• A. Syringe
• B. Infusion pump
• C. Closed system transfer device
• D. Vented needle

Answer: (C)

The use of a closed system transfer device (CSTD) is essential in sterile compounding because it is specifically designed to minimize the risk of exposure to hazardous drugs. CSTDs create a sealed environment that prevents the release of aerosols, vapors, and droplets during the preparation and transfer of sterile medications. This is particularly important in protecting healthcare workers and patients from potential contamination and harm.

A closed system transfer device operates by allowing for the safe transfer of liquids without exposing the compounds to the external environment. The systems typically utilize valves and seals that open and close in a controlled manner, preventing any escape of particles and aerosols that could occur with other methods of transfer.

In contrast, other options like syringes and vented needles do not provide this level of containment. While infusion pumps may support medication delivery, they do not directly prevent aerosol release during compounding. The primary purpose of a CSTD aligns with the need for safety and sterility in the compounding environment, making it the correct choice for preventing undesirable exposure to potentially hazardous compounds.
