Problem: The nurse is due to increase the patients Pitocin to 4mu/min. There is 500mL of lactated Ringers mixed with 30 units of Pitocin. At how many ml/hr should you set the pump? *Rounding rule: IV pump setting with a specific medication = round to the 10ths place Hint: Note that there are 1000 milliunits (mu) per unit of medication. Some students like to calculate the number of mu per milliliter to begin with, others like to include that in the dimensional analysis equation.
