A nurse is caring for a client who has a Clostridium difficile infection. Which of the following cleansing agents should the nurse use for hand hygiene?

A. Wearing a protective gown is necessary when caring for a client with C. difficile to prevent the spread of spores and protect the nurse from contact with contaminated surfaces.
B. Placing the client in a private room helps to isolate the infection and prevent transmission to other patients, which is essential in managing C. difficile infections.
C. An N-95 respirator is not required for C. difficile as the primary mode of transmission is via the fecal-oral route, not through airborne particles.
D. A negative pressure room is used for airborne infections like tuberculosis, not for C. difficile. C. difficile requires contact precautions rather than airborne precautions.
E. A mask is not necessary for the client with C. difficile when leaving the room; instead, hand hygiene and proper gowning are essential for preventing the spread of the infection.

A. "A culture identifies an antibiotic's effect on a pathogen.": Cultures do not determine the effect of antibiotics on pathogens; they identify the presence of pathogens and their susceptibility to antibiotics.
B. "A culture determines the appropriate medication dose.": Cultures do not determine medication doses; they identify pathogens and guide antibiotic selection based on susceptibility testing.
C. "A culture measures antibiotic levels.": Cultures do not measure antibiotic levels; they identify pathogens and their susceptibility to antibiotics.
D. "A culture identifies the presence of pathogens.": This is the correct explanation. A wound culture is performed to identify any microorganisms present in the wound, such as bacteria or fungi, which helps guide appropriate treatment.
