Nurses play a critical role in resistance prevention through various practices: 1. Education: Educating patients about the importance of completing prescribed antibiotic courses and not demanding antibiotics for viral infections. 2. Infection Control: Implementing strict infection control measures, such as proper hand hygiene, to prevent the spread of resistant organisms. 3. Antibiotic Stewardship: Collaborating with healthcare teams to ensure antibiotics are used appropriately and only when necessary.
