Which size syringe is typically used for flushing a PICC line?

• A. 5 mL
• B. 10 mL
• C. 20 mL
• D. 30 mL

Answer: (B)

The 10 mL syringe is typically used for flushing a PICC (Peripherally Inserted Central Catheter) line to prevent occlusion and maintain the patency of the catheter. Using a syringe of this size is important because it strikes a balance between providing enough volume to effectively push the saline or medication through the line without exerting excessive pressure. Clinical guidelines recommend a minimum of a 10 mL syringe specifically for flushing because smaller syringes (like a 5 mL) can generate higher pressures that may damage the PICC and increase the risk of complications, such as catheter rupture or embolism. Larger syringes, such as 20 mL or 30 mL, may provide more volume but are generally not necessary for routine flushing and can also create unnecessary volume in certain clinical scenarios. Thus, the 10 mL syringe is the standard for this procedure.
