A nurse at a long-term care facility is caring for a client who has AIDS. The client accidentally spills the contents of their urinal on the floor.
After cleaning up the spill with soap and water, the nurse should apply a solution of water and which of the following disinfectants to the floor?
Isopropyl alcohol.
Chlorhexidine.
Hydrogen peroxide.
Bleach.
The Correct Answer is D
Bleach.
According to the CDC, bleach is an effective disinfectant for environmental surfaces contaminated with blood or body fluids from a person with AIDS or other bloodborne pathogens. Bleach can kill HIV and hepatitis viruses when used in a 1:10 dilution with water.
Choice A is wrong because isopropyl alcohol is not recommended for disinfecting environmental surfaces. It can evaporate quickly and may not have enough contact time to kill the pathogens.
Choice B is wrong because chlorhexidine is an antiseptic, not a disinfectant. It is used for skin cleansing or wound irrigation, but it is not effective against spores or non-enveloped viruses.
Choice C is wrong because hydrogen peroxide is a low-level disinfectant that can be inactivated by organic matter.
It is not suitable for disinfecting surfaces contaminated with blood or body fluids.
