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?
Hydrogen peroxide.
Isopropyl alcohol.
Chlorine.
Triclosan.
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A rationale
Suctioning a tracheotomy involves contact with respiratory secretions which can be infectious. Protective eyewear is necessary to prevent exposure to potentially infectious fluids.
Choice B rationale
Changing a baby’s diaper involves exposure to feces and urine, but does not usually require protective eyewear as splashing is not common.
Choice C rationale
Applying a dressing on the leg generally does not involve significant risk of splashes or sprays to the eyes, making protective eyewear unnecessary.
Choice D rationale
Gathering linens off a contaminated bed poses some risk of contamination, but typically does not involve splashes or sprays that would necessitate protective eyewear.
Correct Answer is B
Explanation
Choice A rationale
Breaking needles in half before disposal is dangerous and not recommended. It increases the risk of needlestick injuries and exposure to bloodborne pathogens.
Choice B rationale
Not recapping needles, especially after drawing arterial blood gas (ABG) specimens, is a recommended practice to prevent needlestick injuries. This reduces the risk of accidental puncture during the recapping process.
Choice C rationale
Recapping needles and placing them in a wastebasket is unsafe and increases the risk of needlestick injuries and improper disposal of medical waste, which can expose others to bloodborne pathogens.
Choice D rationale
Placing uncapped needles directly into a puncture-proof container after use is a safe practice, but the question specifically asks about preventing needlestick injuries during the handling of ABG specimens, where recapping should be avoided.
