17. Instruments sterilized with a disinfectant are recommended for
A. dental procedures.
B. any outpatient surgery.
C. suturing major skin lacerations.
D. all procedures. (this is a tricky one – Disinfection only reduces the number of microorganisms whereas sterilization is the method of complete removal of the microorganisms – so instruments are not truly sterile if only using a disinfectant. For dental procedures, because mouths are dirty, you can’t really keep things sterile – but you also don’t want ant tissue/germs on instruments from a prior animal – so proper sterilization is best, ***** ***** an instrument is washed then soaked in a disinfectant solution like chlorhexidine, it can be acceptable to do things in the ‘dirty mouth’ or a wound like a laceration that is contaminated, too many variables for an outpatient surgery I think but generally would be ‘clean’ procedures and not needing to be super sterile like a bone surgery. More than you probably wanted to know but I don’t like the wording of the question or the choices!!)
