#4
What is the function of a sterile processing technician?
To sterilize medical instruments
ExplanationPerforms procedures to ensure instruments are free from microorganisms.
#5
What is the primary risk associated with improper sterilization processes?
Infection transmission
ExplanationPotential for pathogens to remain on instruments, leading to infections.
