Final answer:
Disinfection immersion liquids should be changed daily to ensure their efficacy in killing pathogens, especially in environments like healthcare where sanitation is critical.
Step-by-step explanation:
All disinfection immersion liquid must be changed daily or sooner if visibly contaminated. The correct answer is c) Daily. Proper disinfectant practices are crucial in order to maintain a safe and sanitary environment. A disinfection solution can become contaminated with microorganisms, especially if the tools being disinfected are not pre-cleaned properly or if the liquid becomes diluted with use. Therefore, replacing the liquid daily helps ensure that it maintains its efficacy in killing pathogens. In some settings, such as healthcare, the guidelines set by organizations like the Centers for Disease Control and Prevention (CDC) or local regulatory agencies may specify even more stringent measures.
