which principle of surgical asepsis, if any, has the nurse violated if while preparing to do a sterile dressing change the nurse accidentally sneezes over the sterile field that is on the over - the - bed table?
none of the principles were violated.
fluid flows in the direction of gravity.
a sterile field becomes contaminated by prolonged exposure to air.
when a sterile field comes in contact with a wet surface, the sterile field is contaminated by capillary action.

Explanation:

Sneezing over a sterile field can introduce contaminants from respiratory droplets. This violates the principle that a sterile field can become contaminated when exposed to non - sterile elements. In this case, the droplets from the sneeze are non - sterile and can contaminate the field.

Answer:

None of the provided options are correct. Sneezing over a sterile field violates the principle that a sterile field can be contaminated by contact with non - sterile substances (such as respiratory droplets). If we must choose from the given options, the closest one is that a sterile field becomes contaminated by contact with non - sterile elements (but this is not exactly stated in the given options).
