- APlace the implement directly into the disinfectant solution.
- BWipe the implement with a dry, sterile cloth.
- CThoroughly wash the implement with soap and water.
- DSoak the implement in an antiseptic solution for 5 minutes.
Show answer & explanationAnswer & explanation
Correct answer: C. Thoroughly wash the implement with soap and water.
Visible debris, such as hair and skin cells, can prevent disinfectants from effectively reaching and killing pathogens. Therefore, cleaning with soap and water to remove this organic matter is a mandatory pre-step before disinfection.
Why the other options are wrong
- A. Placing an implement with visible debris directly into disinfectant will render the disinfectant ineffective due to organic load.
- B. Wiping with a dry cloth is insufficient to remove all organic debris and pathogens required for effective disinfection.
- D. Antiseptics are for skin, not for disinfecting implements, and soaking without prior cleaning is ineffective for disinfection.
Pre-Cleaning for Disinfection
The essential first step in the decontamination process for non-porous implements, involving the physical removal of all visible debris and organic matter using soap and water, before disinfection can occur.
- Removes organic load (hair, skin, blood) that can inactivate disinfectants.
- Must be done before applying any disinfectant.
- Usually involves scrubbing with soap and water.
