%5 Dextrose in water, TKO usually means to "keep vein open" "to keep open" - which is about 1ml/hour. Other posters have said it is %5 dextrose in normal saline, that is not correct, that would be D5NS. This is D5W.

this is not accurate or complete information. it may be for the facility you practice in and it probably applies specifically to iv pumps that default to this rate, but not for others where they practice. this question of tko came up recently in the nursing student assistance forum and i supplied the correct answer. please read it for yourselves: TKO IV question - tko iv question
0.9% normal saline is an isotonic solution. Usually used as a vascular volume expander.
Sterile water is hypotonic by itself, but mixed with 5% Dextrose, it is an isotonic solution, until the dextrose is absorbed. Then the body is left with a hypotonic solution which will move into the interstitial and intercellular spaces. There are risks to long term D5W therapy.
Thank you for such a detailed response! For some reason, I am really struggling with my IV Therapy..I had done very well in Pharm so I didnt think I would have any problems..but this class is turning out to be my most challenging. Again..Thanks!
