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

The correct answer is Choice C. Choice A rationale: While maintaining a distance of 3 feet can reduce the risk of direct contact transmission, it is not the most effective measure for contact isolation precautions. Contact isolation aims to prevent the spread of pathogens that can be transmitted through direct or indirect contact with the infected person or contaminated objects. A distance of 3 feet may not be sufficient to prevent transmission via droplets or fomites (inanimate objects that can harbor infectious agents). Choice B rationale: Sterile gloves are not routinely required for contact isolation precautions. They are primarily used for sterile procedures or when there is a risk of exposure to blood or body fluids. For contact isolation, standard clean gloves are usually sufficient to protect against transmission via direct contact. Choice C rationale: Leaving equipment that is used routinely in the client's room is a crucial part of contact isolation precautions. This practice prevents the spread of infection by minimizing the movement of potentially contaminated items outside of the isolation room. Equipment like stethoscopes, blood pressure cuffs, and thermometers should be dedicated to the client's use and not shared with other patients. Choice D rationale: Negative-pressure airflow rooms are used for airborne isolation precautions, which are designed to prevent the spread of pathogens that can be transmitted through the air. Contact isolation does not specifically require a negative-pressure room, as the primary mode of transmission is through direct or indirect contact, not airborne particles.
