93. A large spill has occurred in a laboratory involving venous blood. Which of the following actions should the phlebotomist take?

Answer: B

Explanation:

Pour bleach on the spill and let it soak for 60 seconds.

Pouring bleach on the spill and allowing it to soak for 60 seconds is the appropriate action to disinfect the area and neutralize any potential pathogens present in the venous blood.

A) Cover the spill until maintenance arrives.

Covering the spill may prevent further exposure temporarily, but it does not address the contamination issue. This action does not disinfect or neutralize the hazardous materials, which is critical in a laboratory setting.

B) Pour bleach on the spill and let it soak for 60 seconds.

This is the correct response as bleach is an effective disinfectant that can kill most pathogens present in blood. Allowing it to soak ensures that the disinfectant has adequate contact time to effectively eliminate harmful microbes.

C) Evacuate the laboratory.

While evacuating the laboratory may be necessary in some hazardous situations, it does not provide a solution to the immediate contamination. This action alone does not mitigate the risk posed by the blood spill and may leave the area unsafe for others.

D) Apply a liquid thickening agent on top of the spill.

Applying a thickening agent may help to contain the spill temporarily, but it does not disinfect the area. This action does not effectively eliminate the potential risk of infection from the blood, making it an inadequate response.

Conclusion

The correct answer, pouring bleach on the spill and allowing it to soak, is essential for effective decontamination in a laboratory environment. Other options either fail to address the contamination adequately or do not provide a long-term solution to ensuring safety in the laboratory. Proper disinfecting procedures are crucial in managing biological hazards effectively.
