Peripheral IVs should be flushed every how many hours?

• A. Every 6 hours
• B. Every 12 hours
• C. Every 2 hours
• D. Every 24 hours

Answer: (B)

Regular flushing keeps a peripheral IV patent and reduces the risk of occlusion, thrombus formation, and vein irritation. Flushing at a set maintenance interval of about every 12 hours when the line isn’t actively in use helps maintain patency without unnecessary manipulation of the vein. Flushing more often (every few hours) isn’t usually required for a standard peripheral line and can increase vein irritation and infection risk; flushing too infrequently (every 24 hours) raises the chance of occlusion. If the line is in use for intermittent medications or continuous infusions, flush before and after each use per policy to maintain patency. Use saline with a 10 mL syringe using aseptic technique and monitor the insertion site for signs of complications.
