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. Uncapped sharps are put in a puncture-resistant container: Proper disposal of sharps in a puncture-resistant container reduces the risk of needlestick injuries and infection. This is a safe practice and does not pose an infection risk to an immunocompromised client. B. Dampened cloths are used for dusting the area: Using dampened cloths for dusting helps prevent airborne particles from spreading, reducing the risk of inhaling harmful pathogens. This method is considered appropriate for infection control. C. Waste containers are lined with single bags: Using single-lined waste containers is a standard infection control practice that helps contain biohazardous waste properly. It does not pose a significant infection risk when handled correctly. D. Soiled linens are placed on the floor: Placing soiled linens on the floor increases the risk of contaminating the environment with pathogens, which can be dangerous for an immunocompromised client. Linens should be placed in designated hampers immediately to prevent cross-contamination and the spread of infections.
