Show answer & explanationAnswer & explanation
Correct answer: D. Cleaning them with soap and water, then immersing them in an EPA-registered disinfectant.
Proper disinfection of non-porous tools involves both cleaning and then immersing them in an appropriate disinfectant to kill pathogens. Cleaning removes debris that can hinder disinfectant effectiveness.
Why the other options are wrong
- A. UV sterilizers are often used for storage, but do not replace chemical disinfection for soiled tools.
- B. Rinsing with hot water is a cleaning step, but it does not disinfect the tools.
- C. Antiseptics are for skin, not for disinfecting tools, and air-drying alone is insufficient.
