- DSoak the tool in an antiseptic solution.
Show answer & explanationAnswer & explanation
Correct answer: C. Thoroughly clean the tool with soap and water.
Before any disinfection process can be effective, all visible debris and organic matter must be removed from the tool. Cleaning with soap and water physically removes these contaminants, allowing the disinfectant to work properly.
Why the other options are wrong
- A. Placing a dirty tool directly into disinfectant will render the disinfectant ineffective, as organic matter can shield microbes and inactivate the chemical.
- B. Alcohol wipes are not effective for removing all visible debris and organic matter, nor are they a substitute for proper cleaning.
- D. Antiseptics are for living tissue and are not sufficient for cleaning tools before disinfection.
Tool Pre-Cleaning
The essential first step in tool decontamination, involving the physical removal of all visible debris and organic matter using soap and water prior to disinfection or sterilization.
- Removes organic matter (blood, skin cells) that can inactivate disinfectants.
- Must be done before disinfection or sterilization.
- Typically involves scrubbing with a brush under running water and detergent.
Memory trick: Clean First, Disinfect Second, Sterilize if Needed.
