What must be done to instruments that have been sterilized with aldehydes before using them?

• A. They must be placed in alcohol.
• B. They must be rinsed with sterile saline.
• C. They must be cooled.
• D. They must be exposed to air.

Answer: (B)

Aldehyde sterilization can leave residual chemical compounds on instruments, and those residues can be toxic or irritating to tissues. To make sure the instruments are safe to use, they should be rinsed thoroughly with sterile saline to wash away any remaining aldehyde residues. This step reduces the risk of chemical injury and helps maintain sterility without introducing new contaminants. Other options don’t accomplish this cleansing effectively. Placing instruments in alcohol won’t remove aldehyde residues and could introduce another chemical that may irritate tissue. Cooling or simply exposing the instruments to air doesn’t eliminate the residues. Sterile saline rinse is the appropriate, effective method to ensure the instruments are safe for use.
