NBSTSA Review (Sterilization & Microbiology)

NBSTSA Review (Sterilization & Microbiology)Which of the following situations would present a problem when preparing instruments for sterilization using a paper-plastic peel pack? A. The instruments within the paper-plastic peel pack have been held together with tape to avoid shifting. B. The instruments should be placed in the paper-plastic peel pack with the rings at the end that was sealed by the manufacturer. C. A Felt-tip marker was used to label the plastic on the paper-plastic peel pack prior to sterilization. D. The open end of the paper-plastic peel pack has been sealed with tape. A. The instruments within the paper-plastic peel pack have been held together with tape to avoid shifting. Which of the following spore-forming microorganisms are used as biological monitors for checking steam sterilization effectiveness for a load of instruments in a rigid container? A. Mycobacterium tuberculosis B. Bacillus stearothermophilus C. Streptococcus pyogenes D. Bacillus atrophaeus B. Bacillus stearothermophilus Bacillus stearothermophilus, a highly heat-resistant, spore-forming microorganism that does not produce toxins and is non-pathogenic, is used as the biological monitor for steam sterilization. Bacillus atrophaeus is a biological monitor used for ethylene oxide sterilization. Mycobacterium tuberculosis is not used for biological monitoring. Streptococci pyogenes is not used for biological monitoring. If two basins are wrapped together for sterilizing, they should be packaged with one basin: A. stacked inside the other and wrapped in a towel B. stacked inside the other and separated by a towel C. stacked inside the other and separated by impervious material D. on its side and the other upside down B. stacked inside the other and separated by a towel
