How much normal saline do you flush a saline lock with?

• A. 10cc
• B. 5cc
• C. 15cc
• D. 20cc

Answer: (B)

Flushing a saline lock is an essential procedure to maintain patency and ensure that the IV line is clear for medication administration or fluid delivery. The standard practice generally indicates that flushing with 5cc (or 5 milliliters) of normal saline is sufficient to achieve this goal. This amount is adequate to clear any potential blood backflow and confirm that the saline lock is functioning properly without over-inflating the line or causing discomfort to the patient. When determining the volume to use, factors such as the gauge of the catheter and the clinical scenario may influence this decision, but 5cc is the commonly accepted standard for routine flushing in most situations, making it an effective choice for maintaining IV access.
