A client weighs 200 lb. Available is 25,000 units of heparin in
1000mL D5W. The physician orders heparin sodium IV bolus of 80
units/kg and starts the drip at 14 units/kg/hour. What is the
correct IV rate in milliliters per hour? Round to the nearest whole
number.
A. 51
B. 52
C. 53
D. 54
Option A - 51 is correct.
Physician's order: heparin sodium IV bolus of 80 units/kg.
Maintenance drip rate set at 14 units/kg/hour
Patient's weight: 200lb
Dose available: 25,000 units of heparin in 1000mL D5W
Weight in kg = 91kg
Total dose of heparin to be administered = 14 x 91/hour
= 1,274 units/hour.
Here 1000ml = 25,000units.
'X' ml = 1274 units. Apply cross multiplication principles.
=25,000X = 1274 x 1000
X = (1274 x 1000) / 25,000 = 50.96
= 51(round off value)
So infusion rate of heparin should be set at 51ml/hr.
