decontamination - correct answer-is a process in which instruments and supplies are first
cleaned and then processed through chemical or mechanical means so that they are safe for
handling
disinfection - correct answer-is a process that removes mist but not all microbes on
inanimate surfaces. most are not safe for use on tissue.
reprocessing - correct answer-refers to all steps necessary to render soiled medical devices,
including surgical instruments, safe for use on the next patient
sterilization - correct answer-is a process that results in the complete destruction of all forms
of life on an object
before and after a surgical case, the floors, walls, and tables are cleaned using a ? - correct

disinfected, sterilized, and protected form contamination for the next patient.
all equipment used in providing patient care is potentially contaminated with - correct
answer-pathogenic microorganism and must be reprocessed for safe use on the next patient
reprocessing - correct answer-is a step by step procedure that follows an exact protocol,
starting from the point of use and ending with the assembly and sterilization of equipment
used in surgery
nearly all instruments used in surgery are transferred to - correct answer-central processing
for reprocessing
the personnel responsible for CPD are - correct answer-central processing technicians
central processing - correct answer-must make sure that equipment is safe and ready for
scheduled surgery and that thousands of instruments are organized and processed
according to strict standards.
monitoring means - correct answer-checking, recording, and reporting.
single use, or disposable, medical devices, and products have come into extremely
widespread use in the past - correct answer-two decades
