The nurse is caring for a client with a double lumen peripherally inserted central catheter (PICC) line on the right upper extremity, that flushes easily but does not have a blood return. Normal saline is infusing through one port and a vasopressor agent is infusing through the other port. Which intervention(s) should the nurse implement? Select all that apply.

A. Stopping the infusions and inserting a new catheter may not be necessary at this point unless complications develop. B. As long as the catheter is flushing easily and the infusions are not causing complications (such as infiltration), it is appropriate to continue using it. C. Aspirating and flushing the line until a blood return is obtained may cause damage to the catheter or further complications. D. Monitoring for signs of infiltration is crucial, as the inability to aspirate a blood return may indicate a partial occlusion or other issues with the PICC line. E. Replacing the PICC line may not be necessary unless more severe complications are observed.
