A nurse is teaching the patient and family about wound care. Which technique will the nurse teach to best prevent transmission of pathogens?

Choice A reason: Hand washing is the most effective technique to prevent pathogen transmission during wound care, as it removes microorganisms from the hands, reducing contamination risk. It is the foundation of infection control, making it the primary teaching focus for patients and families. Choice B reason: Wearing gloves is important but secondary to hand washing, which must precede glove use to ensure clean hands. Gloves alone do not address hand contamination before or after wound care, making this less effective than hand washing. Choice C reason: Washing the wound removes debris but does not prevent pathogen transmission from the caregiver’s hands to the wound. Hand washing is the primary defense against introducing pathogens, making wound washing a supportive but secondary action. Choice D reason: Wearing eye protection prevents splash exposure but is less critical than hand washing, which directly reduces pathogen transfer during wound care. Eye protection is situational, while hand hygiene is universally essential, making this less effective.
