Which device can be changed based on airflow and is used for preparing nonhazardous drugs?

The correct choice refers to a Clean Air Isolator (CAI), which is specifically designed to provide an aseptic environment for the preparation of nonhazardous drugs. The unique aspect of a CAI is its ability to maintain a controlled airflow environment, which can be altered or adjusted as needed based on specific workflow requirements or the particular protocols desired by the compounding facility.

A CAI creates a negative pressure environment that protects the compounds being prepared from potential contamination by surrounding air particles. This feature is essential for ensuring sterility, particularly in settings where the risk of infection is paramount. The adjustable airflow can help optimize the efficiency of the compounding process, improve safety for the technician, and ensure compliance with regulatory requirements.

While other options like CACI (Compounding Aseptic Containment Isolator) and laminar airflow workbenches serve vital functions in sterile compounding, they do not have the same versatility regarding airflow adjustments specifically for nonhazardous drug preparations. The HEPA filter, while crucial for maintaining air quality, is merely a component of the airflow systems and does not directly serve the purpose of preparing drugs.
