Q1.Hospital A will be performing surgery on a patient with suspected Creutzfeldt-Jakob Disease (CJD). Which statement is false? A.The surgical devices used that are impossible or difficult to clean can be discarded. B.Transmissibility is directly related to the concentration of prions in the tissues. C.A tracking system should be in place that permits recall of devices used in high-risk tissues and high-risk patients. D.Immediate-use steam sterilization (flash sterilization) is permitted to reprocess instruments of this CJD procedure.

Q3.True or False ? Some studies have shown that despite reprocessing in accordance with U.S. guidelines, viable microbes and biological debris persist on clinically used gastrointestinal endoscopes, suggesting current reprocessing guidelines are not sufficient to ensure successful decontamination.
