A nurse is caring for a 2-year-old child who has Clostridium difficile. Which of the following actions should the nurse take?

Rationale: A. Use an N95 respirator: N95 respirators are necessary for airborne precautions, such as with tuberculosis or measles. C. difficile is transmitted via contact with contaminated surfaces or stool, not airborne particles, so an N95 is not indicated. B. Initiate contact precautions: Contact precautions are required for C. difficile because it spreads through direct and indirect contact with contaminated surfaces or stool. Gloves and gowns should be worn, and hand hygiene with soap and water is essential to prevent spore transmission. C. Place the child in a room that has a HEPA filtration system: HEPA filters are used for airborne pathogens or immunocompromised clients, not for enteric infections like C. difficile. This intervention would not reduce transmission risk in this case. D. Instruct the parents to avoid bringing fresh flowers into the room: This precaution is typically for neutropenic or immunocompromised clients to reduce exposure to potential fungal spores. C. difficile precautions focus on containment of fecal-oral transmission routes, not environmental fungal sources.
