If you already have a PIV running with an extension set and you need more ports to run more meds, can you add a double lumen extension set to your original extension set or do you need to put it on at the hub?
That does make sense. But would it also be ok to put a double lumen extension on so I have a free port to push other meds? Does it matter where you add a double or triple lumen? Can you add it to IV hub, single extension or y site on primary tubing?
