I am doing well with dosage calculations except for two types of problems. One is how to tell when your infusion will finish, for example: if you have 250 mL and a flow rate of 25 get/min and set calibration of 10 get/mL. The other is if the order is to infuse 1 liter of D5NS with 10,000 U Heparin at 20 get/min using a set calibration of 15 get/mL, how many units of Heparin is the pt receiving hourly? I would appreciate any help! Thanks!!
