A nurse is providing care to a client who is immunocompromised. Which of the following should the nurse identify as a possible source of infection?

A. Waste containers are lined with single bags: Using single-lined waste containers is standard practice and does not pose a significant infection risk. Properly contained waste helps maintain cleanliness and reduce exposure to pathogens. B. Dampened cloths are used for dusting the area: Using dampened cloths prevents dust from becoming airborne and spreading microorganisms. This method reduces the risk of infection and is appropriate for immunocompromised clients. C. Uncapped sharps are put in a puncture-resistant container: Sharps should always be capped or handled carefully, but placing them directly in a puncture-resistant container is safe and prevents needlestick injuries. D. Soiled linens are placed on the floor: Placing soiled linens on the floor exposes them to environmental pathogens and increases the risk of cross-contamination. For immunocompromised clients, proper handling and containment of soiled linens are critical to prevent infection.
