A nurse is planning care for a client who requires insertion of a peripherally inserted central catheter (PICC) line. Which of the following actions should the nurse plan to take?

A. PICC lines are typically inserted into veins in the upper extremity (e.g., basilic or cephalic vein), not the lower extremities. B. A 10 mL syringe (or larger) is recommended to flush PICC lines to avoid excessive pressure that could damage the catheter; a 3 mL syringe generates too much pressure. C. Flushing the PICC line with 0.9% sodium chloride (normal saline) after medication administration is standard practice to maintain catheter patency and prevent clotting. D. Pneumothorax is a potential complication of central venous catheters inserted in the subclavian or jugular veins, not typically with PICC lines, as they are inserted peripherally.
