CBSPD Sterile Processing Technician Test 2025 – 400 Free Practice Questions to Pass the Exam

Maintaining negative air pressure in specific areas of Sterile Processing and Distribution (SPD) is crucial for controlling the spread of contaminants. The decontamination area is particularly important because it is where soiled instruments and materials are first processed. Negative air pressure in this area helps to contain and minimize the escape of contaminants into adjacent areas, thereby reducing the risk of exposure and ensuring a safer environment for staff and patients.

In addition, the sterilizer access area should also maintain negative air pressure. This area often serves as a transition point where sterilized instruments are moved out of the sterilization process. Maintaining negative pressure here helps ensure that any potential contaminants from outside the sterilization environment do not infiltrate the space.

The Environmental Services closet, while it often contains cleaning supplies and equipment, has a role in preventing cross-contamination. Keeping this area under negative pressure contributes to a controlled environment, further minimizing the risk of spreading contaminants.

The other listed choices encompass areas that do not require negative air pressure in the same way. For example, sterilization and storage areas may not need negative pressure management as their primary function differs, focusing instead on maintaining sterility and organization after items have been properly processed.
