American Society for Clinical Pathology (ASCP) Histotechnician Certification Practice Exam

What is the appropriate procedure for cleaning a tourniquet before use?

1. Must be wiped down with 70 percent alcohol between patients

2. Must be sterilized in an autoclave

3. Should be replaced after each use

4. Can be cleaned with soap and water

The correct answer is: Must be wiped down with 70 percent alcohol between patients

Wiping down a tourniquet with 70 percent alcohol between patients is the appropriate procedure because this concentration of alcohol effectively kills most bacteria, viruses, and fungi, thus minimizing the risk of cross-contamination between patients. This practice is critical in maintaining the integrity of infection control protocols in clinical settings. Using a lower concentration of alcohol may not provide the same efficacy, and while sterilization methods like autoclaving ensure that equipment is free from all microorganisms, they are not practical for items that cannot withstand high temperatures or moisture. Replacing the tourniquet after each use is excessive and not typically required, as frequent cleaning is generally sufficient for maintaining hygiene. Cleaning with soap and water may not achieve the level of disinfection necessary for effectively combating pathogens, especially in a healthcare environment. Therefore, utilizing 70 percent alcohol strikes the right balance between practicality and the need for effective disinfection.
