Question 1 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:
To calculate mL/hr for heparin infusion, first, determine total units needed per hour: 15 units/kg/hr * 82 kg = 1,230 units/hr. Next, calculate mL/hr using the available concentration: 25,000 units / 250 mL = 100 units/mL. Finally, divide total units needed per hour by units per mL: 1,230 units/hr / 100 units/mL = 12.3 mL/hr. This is the correct answer (
A). Other choices are incorrect because they do not follow the correct calculation method or misinterpret the given information.
