A physician orders NS with 20,000 Units Heparin/Liter @ 2500 Units/hr. You have available Heparin 5,000 Units/ml in a 5 ml vial. How many ml of heparin will be needed to prepare one liter of the solution?
A. 5 ml B. 20 ml C. 4 ml D. 25 ml
Desired dose (dose ordered)= 20,000 IU/ liter
Available dose( dose in hand)= 5000/mL
Quantity (available concentration of drug)= 1mL
Formula for dosage calculation is
D (desired dose) x Q (quantity) = dosage
H ( dose in hand)
20,000 IU x 1 mL = 4 mL
5000 IU
4 mL heparin contains 20,000 IU
Thus the answer is C. 4 mL
