A nurse is walking down the unit hall and sees a blood spill on the floor.
Which of the following agents should the nurse use to sanitize the floor?

Choice A rationale

Normal flora does not function as cell rebuilders. They primarily exist in a symbiotic relationship with the host without directly participating in cell repair processes.

Choice B rationale

While some normal flora aid in digestion, they are not involved in blood production. Blood production is a function of bone marrow and not influenced by normal flora.

Choice C rationale

Normal flora play a crucial role in preventing the colonization of pathogens by competing for nutrients and space, thereby protecting the body from harmful microorganisms.

Choice D rationale

Normal flora do not manage the fluid balance of the body. Fluid balance is regulated by the kidneys and the body's endocrine system, not by the normal flora.

Choice A rationale

Hydrogen peroxide is a disinfectant but not the best agent for cleaning blood spills because it is less effective against a wide range of pathogens found in blood.

Choice B rationale

Isopropyl alcohol is effective against many pathogens but is not recommended for cleaning blood spills as it may not completely eliminate bloodborne pathogens.

Choice C rationale

Chlorine (bleach) is recommended for cleaning blood spills because it is highly effective against a wide range of pathogens, including bloodborne viruses like HIV and hepatitis.

Choice D rationale

Triclosan is an antibacterial agent used in some cleaning products but is not effective against viruses and is therefore not recommended for cleaning blood spills.
