A PCT is asked to set up a sterile field on a small bedside table for a nurse dressing change, with limited space, a wandering roommate, and a need to leave the field briefly. The kit contains a drape, gauze, and solution. Which setup behavior maintains sterile field integrity during preparation?

The correct behavior works because sterile technique requires the outer one-inch perimeter be considered contaminated, the field stay dry and above waist level in direct view, and only sterile items touch the interior, which preserves microbe-free status on a small table. Reaching across to adjust the far corner fails by concept of movement over the field because reaching over allows skin cells, sleeve fibers, and droplets to fall onto the drape even when placement looks tidy. Turning away to answer the roommate fails by concept of continuous observation because an unwatched field is considered contaminated due to possible touch, airflow, or liquid splash during the brief absence. Using the outer edge after touching the table fails by concept of border contamination because the one-inch edge and any wet area wick organisms from nonsterile surfaces onto gauze by capillary action. Exam caveat is that any doubt means rebuild the field and report it rather than hoping it stayed clean. Practical check is to clear space first, check package integrity and dryness, open away from you, and keep the field in sight until handoff.
