Final answer:
Absorbed bench covers should not be changed weekly; they should be changed immediately when visibly contaminated as a part of maintaining hygiene in a healthcare or laboratory setting.
Step-by-step explanation:
The question touches on safety protocols and hygiene practices in a healthcare or laboratory setting to prevent contamination and infection. The statement that is NOT true is 'A. Absorbed bench covers should be changed weekly.' This statement does not adhere to best practices concerning surface disinfection and safety in healthcare or laboratory environments. Rather, absorbed bench covers should be changed immediately when they become visibly contaminated to prevent the spread of infectious agents. Work surfaces should indeed be cleaned immediately when visibly contaminated, gloves should be worn when disinfecting work surfaces, and work surfaces should be cleaned at least once per shift with suitable disinfectant as part of good laboratory practices and to comply with health and safety regulations.
