Final answer:
A medical assistant should follow aseptic technique by pre-cleaning instruments, using sterilants, and working in a sterile field to prevent infection. Sterilization can include autoclaving, using chemical solutions, and ensure all surfaces and tools are initially free of microbes.
Step-by-step explanation:
A medical assistant should employ aseptic technique when cleaning instruments to maintain a sterile environment and prevent infections. Cleaning typically entails several steps, including:
- Pre-cleaning with detergent and water to remove visible dirt and debris.
- Thorough washing with specialized solutions, such as a 1:10 bleach dilution or 1 N NaOH.
- Sterilization of metal tools by autoclaving or heating.
- Disinfection of surfaces and instruments with laboratory-grade disinfectants or 70% ethanol.
- Use of personal protective equipment (PPE) to reduce the risk of spreading microbes during the cleaning process.
Ensuring that instruments are initially free from microbes and maintaining a sterile field are crucial. Proper disposal of contaminated materials and adherence to protocols recommended by authoritative bodies such as the Association of Surgical Technologists are also integral to aseptic technique.
