Final answer:
The correct answer is 5000 parts per million (ppm), which is the acceptable residual level of Ethylene Oxide (ETO) for tissue samples weighing less than 10 grams. the correct option is b. 5000 .
Step-by-step explanation:
The acceptable residual level of Ethylene Oxide (ETO) for tissue less than 10 grams in size is 5000 parts per million (ppm). In the context of health sciences and safety regulations, measurement units like ppm are used to express very low concentrations of substances, such as the allowable levels of sterilants or contaminants in tissues. Calculating and understanding these units is crucial for ensuring the safety of medical processes and patient health.
Ethylene Oxide is commonly used as a sterilizing agent in healthcare settings, and its residual levels post-sterilization must be monitored carefully. Regulations specify maximum residual levels to safeguard against potential toxic effects. In a practical example, if a tissue sample was exposed to ETO for sterilization, it would need to be tested post-treatment to ensure that ETO levels don't exceed the specified safety threshold. In this case, the correct answer reflects the highest permissible concentration of ETO specified for tissues of a small mass.
