A nurse is administering IV insulin at 10 mL/hr. The available medication is 250 units of insulin/100 mL of Normal Saline. How many units/hr of Insulin is the patient receiving?
Given data
Flow rate = 10 mL / hr
Concentration of medication = 250 units/ 100 mL
1 mL = 250/100= 0.25 units
10 mL contains = 0.25 x 10 = 2.5 units.
Or
Formula for dose calculation is
Desired dose/ dose in hand x quantity
Let us take desired dose as ' x'
X / 0.25 x 1 = 10
X = 0.25 x 10 = 2.5 units
The patient receives 2.5 units of insulin per hr.
