A nurse is admitting a client who was prescribed antibiotic therapy and now has a Clostridium difficile infection. Which of the following actions should the nurse take?

Rationale: A. Clostridium difficile spores are resistant to alcohol and can persist on surfaces. Daily disinfection with a sporicidal agent is essential to prevent transmission. B. Alcohol-based hand sanitizers are ineffective against C. difficile spores. Handwashing with soap and water is required after contact with the client or contaminated surfaces. C. A protective environment is used for immunocompromised clients, not for those with C. difficile. D. Masks are not necessary for routine C. difficile care because the bacteria are spread via the fecal-oral route, not airborne.
