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.

Correct Answer is C
Explanation
Clean the cannula prongs daily.
This is because the nasal cannula can become contaminated with bacteria and mucus, which can cause infection and irritation of the nasal mucosa. Cleaning the cannula prongs daily with soap and water can prevent these complications.
Choice A is wrong because humidifiers can help moisten the dry oxygen and prevent nasal dryness and bleeding. Humidifiers should be used for oxygen flow rates higher than 4 L/min.
Choice B is wrong because the cannula prongs should be positioned curving downward in the nose, not upward. This allows for better alignment with the natural direction of airflow and reduces the risk of dislodgement.
Choice D is wrong because keeping the oxygen tubing off the floor is not a specific action for nasal cannula use. It is a general safety measure to prevent tripping and contamination of the tubing.
