Differentiate between a sterile field and a clean field and describe how long a sterile field remains sterile.

Differentiate between a sterile field and a clean field and describe how long a sterile field remains sterile.

• A. A sterile field is completely free of microorganisms; a clean field is free of gross contamination but not sterile; a sterile field remains sterile only as long as its integrity is maintained and no breach occurs.
• B. A sterile field can be kept indefinitely without concern for breach.
• C. A clean field is free of microorganisms; a sterile field is only clean.
• D. Sterile and clean fields are identical.

Answer: (A)

The main idea is that sterility means there are no viable microorganisms on the field, and that state is preserved only while the protective barriers stay intact. A sterile field is created with sterile supplies and strict sterile technique; it remains sterile only as long as its barriers are uncompromised and nothing nonsterile touches it. If a breach occurs—such as moisture, a puncture, or contact with nonsterile items—the field is no longer sterile and must be considered contaminated. A clean field, by contrast, is free of gross contamination but not sterile; it may still harbor microorganisms and is not suitable for sterile procedures. Because there isn’t a fixed clock for sterility, the field stays sterile only as long as its integrity is maintained. Once a breach happens, sterility is lost and the field should be re-established or avoided for sterile tasks.
