Infection ControlCâu 62 / 100
Contaminated instruments cannot be cleaned right away because the office is short-staffed. Why are they placed in a holding solution?
a.It sterilizes the instruments while they wait
b.It replaces the need for ultrasonic cleaning
c.It sharpens the cutting edges of the instruments
d.It keeps blood and debris from drying and hardening on the instruments
Giải thích
A holding solution keeps bioburden moist so it does not dry onto the instruments, which would make later cleaning far more difficult and could shield microorganisms from the sterilant. A holding solution does not sterilize or disinfect and never replaces mechanical cleaning in an ultrasonic unit or instrument washer. It has no effect on instrument sharpness.
