A nurse is reinforcing teaching with a newly licensed nurse about isolation precautions when caring for a client who has a Clostridioides difficile infection. Which of the following information should the nurse include in the teaching?

A. Place dedicated equipment in the client's room: Clostridioides difficile produces spores that survive on surfaces and equipment for prolonged periods. Using dedicated or disposable equipment reduces cross-contamination and transmission to other clients. This is a core component of contact precautions for C. difficile. B. Use an alcohol-based hand rub after caring for the client: Alcohol-based hand rubs are ineffective against C. difficile spores. Hand hygiene must be performed with soap and water to mechanically remove spores from the hands. Relying on alcohol-based products increases transmission risk. C. Place the client in a room with negative air pressure: Negative-pressure rooms are indicated for airborne infections such as tuberculosis or measles. C. difficile is transmitted via the fecal–oral route and requires contact precautions, not airborne isolation. Room airflow modification is unnecessary. D. Wear an N95 mask when in the client's room: Respiratory protection is not required because C. difficile is not spread through airborne particles. Standard contact precautions include gloves and gowns rather than specialized respiratory equipment. An N95 mask does not reduce transmission risk in this infection.
