Which statement by the nursing assistant indicates the need for further teaching regarding infection control measures for patients with Clostridioides difficile (C. diff)?

Choice A reason: Rubbing hands together to remove C. diff spores is correct, as mechanical friction during hand washing with soap and water dislodges spores. C. diff spores are resistant to alcohol, requiring physical removal, making this statement appropriate and not requiring further teaching. Choice B reason: Using soap and water for hand washing is essential for C. diff, as spores resist alcohol-based sanitizers. Soap and water mechanically remove spores, preventing transmission. This statement reflects proper infection control knowledge, indicating no need for further teaching. Choice C reason: Ensuring family members wash their hands frequently is appropriate, as C. diff spreads via fecal-oral transmission. Hand washing with soap and water prevents spore spread to others, making this statement correct and consistent with infection control protocols. Choice D reason: Claiming alcohol-based sanitizers are most effective for C. diff is incorrect, as spores are resistant to alcohol. Soap and water are required to physically remove spores. This statement indicates a misunderstanding of C. diff infection control, necessitating further teaching.
