88. Which of the following is an appropriate choice for cleaning a surface contaminated with blood or body fluids

Answer: B

Explanation:

10% bleach solution is the appropriate choice for cleaning a surface contaminated with blood or body fluids.

Using a 10% bleach solution effectively disinfects surfaces that may harbor pathogens from blood or body fluids, making it a suitable choice for this context.

A) Boiling water

Boiling water is not an effective disinfectant for surfaces contaminated with blood or body fluids, as it may not reach the necessary temperature consistently across all areas. Additionally, boiling may not adequately eliminate all pathogens, particularly those that are resistant or require chemical disinfectants for complete inactivation.

B) 10% bleach solution

A 10% bleach solution is a powerful disinfectant that is effective against a wide range of pathogens, including viruses and bacteria found in blood and body fluids. Its strong oxidative properties make it ideal for decontaminating surfaces, ensuring that harmful microorganisms are effectively neutralized.

C) Povidoneiodine

While povidone-iodine is a good antiseptic for skin and minor wounds, it is not recommended for cleaning surfaces contaminated with blood or body fluids. Its residual properties are better suited for skin application rather than for disinfection of hard surfaces, where bleach solutions are more effective.

D) 70% isopropyl alcohol

Although 70% isopropyl alcohol is a good disinfectant for many surfaces, it is not the first choice for blood or body fluid contamination due to its inability to effectively kill certain viruses and bacterial spores in the presence of organic material, like blood. It is also less effective than bleach for thorough decontamination in these scenarios.

Conclusion

The 10% bleach solution stands out as the most effective option for cleaning surfaces contaminated with blood or body fluids due to its strong disinfectant properties. Other options, while useful in different contexts, do not provide the same level of efficacy against the wide range of pathogens typically found in such contaminations. Therefore, the choice of a bleach solution is essential for ensuring proper disinfection and safety.
