Question

8 multiple choice 1 point during routine cleaning of an intensive care unit, staff notice evidence of biofilm formation on high - touch surfaces. what is the most effective action to eradicate the biofilm according to infection control protocols? increase the concentration of the disinfectant without prior cleaning replace the surface immediately without cleaning use uv light solely to eradicate the biofilm perform mechanical removal followed by extended contact time with an epa - approved disinfectant clear my selection

Explanation:

Biofilms are complex communities of microorganisms protected by a matrix. Mechanical removal dislodges the biofilm structure, and extended contact time with an EPA - approved disinfectant ensures killing of remaining microorganisms. Increasing disinfectant concentration without cleaning won't effectively penetrate the biofilm. Replacing the surface is not practical or necessary. UV light alone may not completely eradicate the biofilm.

Answer:

D. Perform mechanical removal followed by extended contact time with an EPA - approved disinfectant
