How often should peripheral IV tubing be changed to maintain safety?

• A. Every 72 hours
• B. Every 24 hours
• C. Every 7 days
• D. Only when visibly soiled or malfunctioning

Answer: (C)

Regular changes of peripheral IV tubing help prevent infection and keep the line functioning. Changing the tubing every seven days provides a routine that reduces the chance for microbial growth on the tubing and at the injection ports, while avoiding unnecessary frequent handling of the IV system. If there are signs of infection at the site, the line is not functioning well, or contamination is suspected, tubing should be changed sooner. Waiting until the tubing is visibly soiled or malfunctioning isn’t ideal because problems can develop without obvious signs, increasing risk. So, the guideline reflected here is a seven-day interval, with earlier changes if complications occur.
