5% dextrose solution is also considered hypotonic compared with blood, because although it is isotonic while infusing, the dextrose is metabolized and free water is left, which is hypotonic.

too much internal pressure, caused by water, will come from a hypotonic solution. when there is more concentration of water outside of a cell, it will compensate by taking in as much as possible to reach its equilibrium. if the pressure is too great, the cell will rupture.

hope this helps.

I hope this helps!

If I remember reading correctly from other posts, pansyrose s already a nurse. Pansyrose graduated from a school in Jordan I believe and is working at a hospital there and has no time to read the books because they are too heavy to carry from the hospital to the hostel, therefore the constant posts for help! Not sure how pansyrose was able to graduate in Jordan because my school in Philly would not advance you if you could not answer the questions that pansyrose posts about after graduation. However I learn from the posts, but then again I have one more year of school left.

This is off the topic, but...

pansyrose, I love your "I want to know, I want the answer now, and why" lines.

You make me chuckle to no end. I hope the service here in AllNurses have been pronto (or stat) enough for ya. ;)

My guess is that too much sugar is really bad for people who suffer from DKA...so salty water it is!

D5W is hypotonic, and a solution of a lower concentration will automatically diffuse to a higher concentration, and so D5W can lead to hyponatraemia which may cause cerebral edema.
