Hello, I don't know if this is right but this is what I got for your questions: 1) 100U/50ml so I did 100U divided by 50ml and that gave me 2u/ml and then I said 6ml/hr times 2U/ml, so the ml cancelled out then 6 times 2 gave me "12U/hr". So the patient is receiving 12u of insulin each hour as long as the pump is set for 6ml/hr. 2) I am not for sure about this one. The only thing I could figure out is in order to give 40,000U and the vial of heparin is 25,000U/ml then in order to get 40,000U: you would need to say 40,000U divided by 25,000U times 1ml and that will give you "1.6ml" that is what you will need to draw from the vial to get 40,000U of heparin. Then mixing that with NaCl 0.9%. I thought that had to be given to you. I was not for sure what to do once I got the 40,000U in my syringe. Sorry:o 3) The way that I figured this was: 60mmol K+ divided by 500ml = 0.12 mmol K+ per 1ml. Then I did 500ml divided by 3hrs= 166.66667ml/hr. Once I got that then I could get mmol K+ per hour by taking the 0.12mmol K+ per 1ml times the 166.66667ml per hr and that = "20mmol K+ per hr the patient will receive".
