For IV lines that are not being used, flush saline locks with 10 mL of NS at least every 24 hours. This statement is:

• A. True
• B. False
• C. Only when the line is expected to be unused
• D. Flush every 12 hours

Answer: (B)

Regular maintenance for unused IV lines hinges on keeping the saline lock patent through periodic flushing. Waiting up to a full day without flushing allows clots to form and can occlude the line. The standard approach is to flush the saline lock every 8 to 12 hours, and again before and after any use of the line. A 10 mL normal saline flush is a common amount used to clear the lock and push any potential clot back into the vein. Therefore, scheduling a flush interval of 24 hours does not meet typical guidelines, even though the line is not being used. Always follow your facility’s policy, but the key idea is regular, more frequent flushing than every 24 hours to maintain patency.
