  1. For children, heparin sodium is administered by intermittent intravenous infusion in a range of 50 to 100 units/kg body weight every 4 hours. For a 50-lb. child, calculate the range, inmilliliters, of a heparin sodium injection containing 5000 units/mL to be administered daily.

NOTE: The answer should be 1.36 to 2.73mL heparin sodium injection

Expert Solution

Child’s weight in kg = 50 lb + 2.2 lb/kg = 22.7 kg

Dosage range for the child = 50 to 100 units/kg X 22.7 kg = 1135 to 2270 units

Daily dosage range in units = 1135 to 2270 units X 6 (doses per day) = 6810 to 13,620 units

Daily dosage range in mL = 6810 units + 5000 units/mL = 1.36 mL, and 13,620 units + 5000 units/mL = 2.72 mL; thus

1.36 mL to 2.72 mL heparin sodium injection. (Answer).
