29. 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 an appropriate choice for cleaning a surface contaminated with blood or body fluids.

A 10% bleach solution is effective in disinfecting surfaces contaminated with blood or body fluids, as it can kill a wide range of pathogens, including viruses and bacteria.

A) Boiling water

Boiling water is not a reliable method for cleaning surfaces contaminated with blood or body fluids, as it may not reach all areas effectively and does not have the necessary disinfectant properties to eliminate pathogens.

B) 10% bleach solution

A 10% bleach solution is specifically recommended for disinfecting surfaces contaminated with blood or body fluids due to its strong virucidal and bactericidal properties. It is effective against a wide range of microorganisms, making it a suitable choice for ensuring safety in such circumstances.

C) Povidone-iodine

Povidone-iodine is primarily used as a skin antiseptic rather than a surface disinfectant. While it is effective against some pathogens, it is not specifically designed for cleaning contaminated surfaces and may not provide adequate disinfection against all infectious agents present in blood or body fluids.

D) 70% isopropyl alcohol

While 70% isopropyl alcohol can be effective for disinfecting certain surfaces, it is not as effective as a bleach solution for blood or body fluid contamination. Alcohol may not eliminate all types of pathogens present in such fluids, particularly certain viruses and spores.

Conclusion

The 10% bleach solution stands out as the most appropriate option for cleaning surfaces contaminated with blood or body fluids due to its proven effectiveness in killing a broad spectrum of pathogens. Other options, while they may have some disinfectant properties, do not provide the same level of assurance in eliminating all potential infectious agents present in these situations. Thus, using a bleach solution is the best practice for ensuring a safe and hygienic environment.
