According to safe EN guidelines, how often should the administration set be changed for open systems?

• A. Every 12 hours.
• B. Every 24 hours.
• C. Every 48 hours.
• D. Every 72 hours.

Answer: (B)

Open enteral feeding setups are exposed to the environment, which raises the risk of microbial contamination as the system is used. To minimize this infection risk, the administration set should be changed daily. That’s why every 24 hours is the standard for open systems. Changing it more frequently isn’t generally required for safety and adds workload, while extending beyond 24 hours would increase contamination risk in open setups.
