question 22 of 25
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 introduces microorganisms from the respiratory tract, contaminating the field. This violates the principle that a sterile field should be protected from contaminants. None of the other listed principles (fluid - gravity, air - exposure, wet - surface contamination) are relevant to sneezing over the field.

Answer:

None of the above options are correct as sneezing over a sterile field violates the principle of keeping the sterile field free from contaminants. If we must choose from the given options, the closest understanding is that the act contaminates the field, but the provided options do not accurately capture this violation. However, if we assume the question is asking which of the listed principles is NOT violated, then the answer is:
Fluid flows in the direction of gravity.
