I know how to calculate infusion time easily when given ml/hr. But my instructor gave us practice problems where we had to calculate infusion times when given gtt/min. I am so lost on this. I don't even know where to start. I'm in Louisiana and we have been out of school since Wed. due to the hurricane and I have not been able to contact my instructor either. We are testing on this Tues. and I really need ASAP. Please!!!!
