| Again, you want the answer in ml/hr. Set up the equation so units cancel, 500ml/2000mg (Procainamide concentration), X 2mg/min (Order), X 60min/hr. You need to put in a conversion factor for min to hr because IV pumps infuse in ml/hr. Result 60,000 ml / 2,000 hr. Solve for ml/hr. 500 ml x 2 mg x 60 min = 60,000 ml = 30 ml/hr (mg and min cancel out) 2000 mg 1 min 1 hr = 2,000 hr Good Luck, Mark RN |
