Maybe I should know this..but I don't...and I can't find any literature on this. If a patient has a triple lumen feeding tube...first g-tube...second J tube...and I think third is BAL...Which site is used for the feeding. I have always been told the J tube, due to this type of tubing is used when a patient has difficulty with gastro feeding. And the G-tube used for the medication and the BAL is to left alone. NO MD order present...which should be...but none. And not my patient but overheard the other nurses talking about which one to used...and they all told the nurse in charge of the patient to use the G-Tube. I disagreed stating what i did above....but more importantly said to call the MD to get an order. I guess she decided to use G-tube. So.....does anyone have correct answer other than the real one which is to get an order. Patient has been in facility for over two weeks and it seems funny to me no one has clarified this.
