Final answer:
For a patient in contact isolation due to a bacterial infection, the nurse will most likely implement barrier protection as an intervention to prevent the spread of the infection.
Step-by-step explanation:
A nurse implementing interventions for a patient in contact isolation for a bacterial infection will most likely utilize barrier protection. This includes wearing personal protective equipment (PPE) such as gloves, gowns, and masks when interacting with the patient. The primary objective is to prevent the spread of the infection. Barrier protection is a part of standard precautions to control infection, as recommended by the Centers for Disease Control and Prevention (CDC). It is important to practice stringent hand hygiene and ensure the disinfection of all items coming into contact with the patient. By doing so, healthcare workers protect themselves and other patients from potential cross-contamination.
