A
Feedback:
The unused lumen is kept patent by scheduled flushes with normal saline and/or heparin. Releasing the clamp, if there is one on the exposed section of the catheter, facilitates flushing the catheter and helps in maintaining the patency. When administering medication through an intravenous port, the nurse pinches the tube above the access port and swabs the port with alcohol.
