Certified Surgical Technologist (CST) Practice Exam

Which portion of the surgical gown is considered non-sterile?

1. Outside closure ties

2. Two inches below neckline to table level

3. Upper arms, neckline and axillary region

4. Sleeves, two inches above the elbows to the cuffs

The correct answer is: Upper arms, neckline and axillary region

The portion of the surgical gown that is considered non-sterile includes areas such as the upper arms, neckline, and axillary region. This designation stems from the necessity of maintaining a sterile field during surgical procedures. Specifically, these areas are more likely to come into contact with non-sterile surfaces or individuals, especially when the surgical technologist or surgeon is maneuvering within the surgical environment. In surgical practice, the gown is designed to create a barrier against contamination. The upper arms and axillary region are particularly vulnerable due to their proximity to unsterile areas and the potential for movement that could compromise sterility. While other options define areas that could be seen as sterile or proximal to sterile areas, they do not encompass as broad a region as the upper arms, neckline, and axillary region, which includes a significant portion of the gown that is typically not considered sterile. Thus, focusing on these specific areas provides clarity on which parts of the attire should remain free from contamination to uphold infection control during surgical procedures.
