A nurse is caring for a client who has been placed on contact isolation precautions. Which of the following interventions should the nurse Implement?

A. Inform visitors to remain at least 3 feet away from the client: Maintaining a 3-foot distance is part of droplet precautions, not contact precautions. Contact precautions focus on preventing the spread of infections transmitted by direct or indirect contact, so spatial distancing is not the primary intervention. B. Apply sterile gloves when entering the client's room: Sterile gloves are not required for routine care under contact precautions. Clean (non-sterile) gloves are appropriate to prevent transmission of pathogens when touching the client or contaminated surfaces. Sterile gloves are reserved for invasive procedures. C. Leave all equipment that is used routinely in the client's room: Equipment such as stethoscopes, blood pressure cuffs, or thermometers should remain in the room to prevent cross-contamination. Dedicated or disposable equipment helps reduce the spread of infectious agents to other clients, which is a key component of contact isolation. D. Place the client in a negative-pressure airflow room: Negative-pressure rooms are required for airborne precautions to prevent aerosolized pathogens from leaving the room. Contact isolation does not require negative-pressure airflow, as the primary transmission route is via direct or indirect contact, not airborne particles.
