What is a common misconception about sterile fields?

The notion that sterile gloves prevent all contamination is indeed a common misconception. While sterile gloves are critical in preventing the transfer of microorganisms during surgical procedures and other invasive tasks, they do not guarantee complete protection against all sources of contamination. Factors such as improper glove application, microscopic tears, or the presence of contaminants on the outer surface of the gloves can compromise their sterility. Additionally, gloves can become contaminated when they come into contact with non-sterile surfaces or objects. Therefore, while sterile gloves are an essential part of maintaining a sterile field, they should be used in conjunction with other aseptic techniques to ensure maximum safety and sterility during procedures.

Other options present misconceptions about sterile practices. For example, sterile fields cannot be established just anywhere; they must be set up in a clean, designated area to maintain sterility. Touching the edges of a sterile field can introduce contaminants, and surgical instruments do not remain sterile indefinitely, as they can be compromised by time, environmental factors, and mishandling.
