They should be disinfected routinely to maintain a low microbial load. 34\. \*\*How does overuse of disinfectants contribute to resistance development in microorganisms?\*\* \*\*Answer\*\*: Overuse of disinfectants can allow microorganisms to develop resistance, making it harder to eliminate them with standard disinfection methods over time. 35\. \*\*What is the purpose of personal protective equipment (PPE) during environmental cleaning?\*\* \*\*Answer\*\*: PPE protects cleaning staff from exposure to pathogens and harmful chemicals, reducing infection risk and enhancing safety. 36\. \*\*Describe two best practices for handling mop heads during floor cleaning.\*\* \*\*Answer\*\*: Mop heads should be wrung out regularly to avoid spreading contaminants, and they should be immersed in rinse water every few strokes for thorough cleaning. 37\. \*\*Explain the difference between cleaning and disinfection.\*\* \*\*Answer\*\*: Cleaning removes visible dirt and organic material, while disinfection kills or inactivates microorganisms on surfaces, making both steps crucial for infection control. 38\. \*\*Why are alcohol-based disinfectants ideal for high-touch surfaces?\*\* \*\*Answer\*\*: Alcohol-based disinfectants act quickly, evaporate without leaving residue, and are effective against many bacteria and viruses, making them suitable for frequently touched areas. 39\. \*\*What are the benefits of using a microfiber cloth over traditional cleaning cloths?\*\* \*\*Answer\*\*: Microfiber cloths trap more dirt and bacteria, provide better cleaning results, and reduce cross-contamination risk compared to traditional cloths. 40\. \*\*What role does environmental cleaning play in reducing healthcare-associated infections (HAIs)?\*\* \*\*Answer\*\*: Environmental cleaning reduces the microbial load on surfaces, thereby breaking the chain of infection and lowering the risk of HAIs for patients and healthcare workers.
