Question only asks for ml per hour. That will be the same regardless.

Ml per hour does come out to 2100. The concentration needs to be higher. 200 mcg/ ml would make more sense with rate at 24 ml per hour.

Micro delivery tubing has a flush volume of 0.3 ml, so very small amounts can be delivered IV.

I still am. But I didn't get through nursing school having my SO getting the answers off a message board.


That's what study groups are for. Or....going to the professor and asking them how they got the answer cause you and everyone else has gotten something different.


"have gotten" ...

just being snarky, you illiterate twit ... ...

As a clinical scenario the question is flawed and unrealistic. Fully functional human kidneys can process between 12-14 L of isotonic fluids per day (0.9%NS, LR). In this clinical scenario, assuming the infusion is kept steady they would reach that threshold in 6 hours. But more importantly it's a hypotonic solution, the patient would die of hemolytic anemia and massive edema.

As a math problem the question is fine.

My bad I see what you're saying. Personally I would not feel comfortable running anything at at a rate of less than 5-10 ml per hour. 0.43 ml/hr is pretty unrealistic clinically speaking in my opinion, even if using a microdrip.

We run fluids at 3ml an hour all the time on babies if we want to have it at TKO

Sure a lower infusion rate is fine for KVO but not for delivery of pressors or other meds. But you're right, in infants and neonates fluid management is much more tricky since you can't just blast them with volume to get meds in.
