Question 2 of 5
A continuous heparin infusion is to begin at 15 units/kg/hr for a client weighing 82 kg. Available: 25,000 units of heparin in 250 mL D5W. Calculate the mL/hr. (the pump is capable of delivering in tenths of an mL).
Correct Answer: A
Rationale:
Total dose = 15 units/kg/hr × 82 kg = 1230 units/hr. Concentration = 25,000 units / 250 mL = 100 units/mL. Infusion rate = 1230 / 100 = 12.3 mL/hr.
