A charge nurse is reinforcing teaching with a newly licensed nurse about infection control measures. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

Choice A reason: Droplet precautions need a mask, not always gown and gloves, unless contact is likely. Scientifically, this overstates requirements, as droplet spread (e.g., flu) prioritizes respiratory protection, indicating partial misunderstanding of PPE specifics.Choice B reason: Bleach at 1:20 is too dilute; 1:10 is standard for blood spills. Scientifically, this weakens disinfection, as higher chlorine concentration kills pathogens like hepatitis, showing incorrect grasp of spill management protocols.Choice C reason: Biohazard disposal for soiled dressings prevents pathogen spread, aligning with infection control. Scientifically, this ensures safe waste handling, as dressings may harbor bacteria or viruses, reflecting accurate understanding of standard precautions.Choice D reason: Alcohol doesn’t kill C. difficile spores; soap and water are required. Scientifically, this misapplies hand hygiene, as spore-forming bacteria resist alcohol, indicating a key error in infection control knowledge for this pathogen.
