Which action by a student preparing for a sterile procedure requires follow-up?

Reaching over the sterile field to grab sterile gloves is a practice that compromises the sterility of the field. In sterile procedures, it is essential to maintain the integrity of the sterile area to prevent contamination. The act of leaning over or reaching across a sterile field can transfer microorganisms from a non-sterile area, such as a person's clothing or body, to the sterile field, which poses a significant risk for infection.

In contrast, establishing the sterile field on a dry surface is a necessary step to ensure that there is no moisture which could harbor bacteria. Using slow movements when setting up sterile drapes is also protective as it reduces the likelihood of accidental contamination from sudden movements. Keeping the sterile field at waist level is generally recommended, as this position makes it easier to manage without the risk of accidentally contaminating the sterile items. Therefore, while the other actions contribute to maintaining a sterile environment, reaching over the sterile field is a clear violation of sterile technique that warrants follow-up intervention.
