Which practice is critical when a nurse is caring for a patient in contact isolation?

Wearing a gown and gloves for every interaction is essential when caring for a patient in contact isolation because this practice helps prevent the transmission of pathogens that can be present on the patient's skin or in their environment. Contact isolation is specifically designed for patients who may spread infections through direct or indirect contact. The use of protective equipment, such as gowns and gloves, serves as a barrier, protecting both the patient and healthcare providers from potential infections.

While restricting visitors may contribute to reducing the spread of infection, it is not always feasible or necessary to completely limit all visitors. Instead, it is more crucial to ensure that those who do visit are informed on the proper hygiene practices. The options that suggest not using personal protective equipment or encouraging physical contact directly contradict the fundamental principles of infection control, as these actions would significantly increase the risk of transmitting infections. Hence, the use of appropriate protective gear is a key component of maintaining a safe environment in contact isolation settings.
