To maintain a sterile field, to what height should items be added above the level of the field?

• A. Minimum of 2 inches
• B. Minimum of 4 inches
• C. Minimum of 6 inches
• D. Minimum of 8 inches

Answer: (C)

In aseptic technique, keeping a sterile field free of contamination means adding items to the field from a height that minimizes the chance of catching or dropping contaminants onto the sterile area. The minimum height for adding items is six inches above the level of the field. This distance helps prevent airborne particles or moisture from reaching the sterile surface and reduces the risk of accidental contact with the non-sterile surroundings. Being closer increases contamination risk, while going higher than six inches is fine but not required—the key point is that six inches is the established minimum.
