Final answer:
The best action would be to review the current infection control protocols to identify and correct issues contributing to the rise in infections. This approach aids in targeting root causes and improving practices without contributing to antibiotic resistance.
Step-by-step explanation:
The nurse manager observing an increase in infection rates at a long-term facility should review the current infection control protocols. This is a proactive step that targets the potential root causes of the increased infections. Prescribing antibiotics to all new residents is not advisable, as it can lead to antibiotic resistance and does not address existing infection control issues. Culturing all residents and staff could be resource-intensive and may not offer immediate solutions to infection control problems. Restricting visitors to public places could help reduce the risk of infection but is again not a direct action towards improving infection control practices already in place.
It is critical to understand that misuse and overuse of antibiotics can lead to antibiotic resistance, which is a significant health crisis. Practices such as creating a routine to identify and isolate infected individuals, improving hand hygiene, and careful disinfection of all items are fundamental steps in infection control. Current protocols should be assessed in terms of effectiveness and compliance to ensure they are up to date and being followed correctly. Effective, evidence-based interventions must be the priority for controlling infections within healthcare facilities.
