Question

if a doctor prescribes 30 units of insulin in 500 ml to be administered over 2 hours, how many drops per minute should be administered if the set is calibrated to deliver 20 drops per ml?
i don't know how to get it and i need to show work...

Answer 1

A total of 500 ml have to administered in 2 hours or in 120 minutes.

It is delivering 20 drops/ml so there are 500x20 drops to be delivered, or 10,000 drops.
so the drops/min have to be 10,000/120 = 83 1/3 drops/min

(notice the 30 units does not enter the picture as it merely describes the strength of the insulin in the 500 ml bag)

Answer 2

thank you very much
