ARRT Patient Care Practice Exam

Which of the following steps is NOT recommended when cleaning contaminated surfaces?

1. Cleaning from the most contaminated to the least contaminated

2. Cleaning in a circular motion

3. Cleaning from the top down

4. Cleaning from least contaminated to most contaminated

The correct answer is: Cleaning from the most contaminated to the least contaminated

Cleaning from the most contaminated to the least contaminated is not recommended because it can potentially spread contaminants rather than effectively removing them. The goal of cleaning is to minimize the risk of infection or transmission of pathogens, and starting with the most contaminated areas may lead to contamination of previously cleaned areas. In contrast, techniques such as cleaning in a circular motion can be effective for ensuring the thorough cleaning of surfaces, as this method allows dirt and contaminants to be lifted rather than pushed around. Additionally, cleaning from the top down is a best practice because it prevents debris from falling onto already cleaned surfaces below. Furthermore, cleaning from least contaminated to most contaminated is a more effective approach as it helps to control the contamination spread and ensures that the cleanest areas are addressed first, thereby reducing the overall risk. By following these recommended practices, healthcare workers can maintain a cleaner, safer environment, which is essential in preventing infections and promoting patient safety.
