The three categories of chlorine bleach solutions are

• A. Low level disinfection, high level disinfection and blood and body fluid cleanup and disinfection
• B. Low level disinfection, medium level disinfection and blood and body fluid cleanup
• C. Surface sterilization and cleansing
• D. Basic cleaning and sanitizing

Answer: (A)

Chlorine bleach solutions are grouped by how strong they are at disinfecting, matched to the level of risk and the task at hand. The three categories reflect that: a low level of disinfection for general cleaning of noncritical surfaces, a high level of disinfection for items or situations with higher risk or more stringent cleanliness needs, and a dedicated disinfection approach for blood and body fluid cleanup that accounts for the specific hazards and required procedures.

Low level disinfection is used on everyday surfaces where complete sterility isn’t needed but reducing surface microbes is important. High level disinfection covers situations or equipment that come into contact with mucous membranes or sterile tissues or when more thorough microbial kill is required. Blood and body fluid cleanup disinfection is a specialized category because spills require stronger precautions, proper contact times, and appropriate protective measures to safely neutralize infectious material.

The other options don’t fit because they either introduce a nonexistent “medium level disinfection” category, or they lump together concepts like surface sterilization or basic cleaning with disinfection in ways that don’t align with how chlorine bleach solutions are typically categorized for infection control.
