hello, im new idk how to post a question, so im sorry if i did this wrong. i am working a paper on a pt i had a mo ago. i wrote down on my sbar that the iv access was triple lumen in groin. this is the first pt i had w/a triple lumen and i understand this is a dumb ques, but why would my pt have a triple lumen and would they usually use this as the iv site to infuse ns and piggyback meds?
