Which term describes the process of removing dirt, dust, blood, or other visible contaminants from a surface or equipment?

• A. Cleaning
• B. Disinfection
• C. Sterilization
• D. High-level disinfection

Answer: (A)

The main idea is removing visible contaminants from a surface or equipment. This is cleaning, which involves physically removing dirt, dust, blood, and other debris using water, detergents, and scrubbing or wiping. Cleaning reduces the microbial load and clears residues, but it does not necessarily kill microbes. Disinfection and sterilization focus on reducing or eliminating microorganisms: disinfection targets pathogens to reduce their numbers, sterilization aims to destroy all microorganisms and spores. High-level disinfection is stronger than standard disinfection but still may not inactivate all spores. Since the question emphasizes removing visible contaminants, cleaning is the best fit.
