I have three questions that I just can not get! I think I am over analyzing them. All help is very much appreciated!! D5W 500 ML plus NaCI 20 mEq to be administered at 19 ml/hr. NaCI is supplied in a 40 ML ampule containing 2.5 mEq per ML. How many ML of NaCI will be added to the 500 ML of D5W? Dobutamine 1 G in 250 ML D5 1/2 N.S. Infuse at 12 MCG/KG/MIN for a patien weighing 75LBS. Drop factor is 60 MCGTT/ML. How many MCGTT/MIN? Heparin 30,000 units in 250 ML d5W IV to infuse at 10 ML/HR. You have Heparin 20,000 units/ML. Drop factor is 60 GTT/ML. How many ML of Heparin should be added to the IV solution? Thankyou soooo much!!!!!!
