Which action best supports maintaining medical asepsis in a patient room?

• A. Ignore contaminated surfaces.
• B. Disinfect surfaces periodically without cleaning.
• C. Dispose waste before cleaning.
• D. Clean from least contaminated to most contaminated, wear gloves when contaminated, and disinfect surfaces appropriately; dispose waste properly.

Answer: (D)

Maintaining medical asepsis hinges on a careful sequence of cleaning and handling that minimizes the spread of pathogens. Cleaning from least contaminated to most contaminated prevents carrying dirt and microbes from dirty areas into cleaner ones. Wearing gloves when you anticipate contact with contaminated surfaces protects you and reduces transmission. After cleaning, surfaces should be disinfected to kill remaining microorganisms, especially in patient spaces. Proper waste disposal is essential to keep the environment free from contaminated materials and to prevent spread.

These other actions fall short because ignoring contaminated surfaces allows pathogens to linger; disinfecting without first cleaning leaves organic matter that can shield germs and reduce effectiveness; and disposing waste before cleaning can spread contaminants during the cleaning process.
