Which area mandates surgical scrubs and hair cover for personnel and has a defined separation from restricted areas by signage or a barrier?

• A. Restricted area
• B. Unrestricted area
• C. Semi-restricted area
• D. Operating room

Answer: (C)

Zone boundaries and attire rules are used to prevent contamination as you move closer to the sterile field. In the semi-restricted area, personnel must wear surgical scrubs and a hair cover, and there is a clearly defined separation from restricted areas by signage or a barrier. This combination ensures that only properly attired staff enter closer to the OR, reducing the chance of bringing in contaminants from less controlled areas. The operating room itself is within the restricted area and requires even stricter sterile attire, while unrestricted areas permit street clothes. Hence, the description fits a semi-restricted area.
