The physician has ordered your client to receive Heparin at 15 u/kg/hr. Heparin is available as 25,000 units in 500 ml. Your client weighs 166 pounds. Calculate how many ml/hr to set the IV pump. Round answer to nearest tenth.
The Correct Answer is ["22.6"]
To calculate the IV pump setting, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The client weighs 166 pounds, which is approximately 75.45 kilograms. Next, calculate the dosage in units per hour by multiplying the client's weight in kilograms by the ordered dosage of 15 units/kg/hr, which equals 1131.75 units/hr. Since Heparin is available as 25,000 units in 500 ml, divide the total units in the bag by the volume to find the concentration, which is 50 units/ml. Finally, divide the dosage required per hour by the concentration to find the volume to be administered per hour. Therefore, the IV pump should be set to approximately 22.6 ml/hr, rounding to the nearest tenth.
