Wet disinfectants should be filled and changed _________.

• A. according to manufacturer's instructions
• B. weekly regardless of use
• C. when the container is empty
• D. after every shift

Answer: (A)

Wet disinfectants must be kept at the proper strength and freshness, so they stay effective for disinfection. The product's label tells you exactly when to refill or replace it, including how often to refresh, how to mix it, and how long it remains usable after opening. This guidance accounts for changes in potency over time, evaporation, and possible contamination, ensuring consistent safety and performance.

That’s why following the manufacturer's instructions is the best approach. Replacing weekly regardless of use, waiting until the container is empty, or changing after every shift doesn’t reliably reflect the product’s specific requirements and can lead to either wasted resources or reduced effectiveness.
