Answer: Quantity required for a 0.125 mg dose is 2.5 ml
Explanation:
Given : Available concentration of Digoxin Elixir = 0.05 mg/ml.
That is 0.05 mg is present in 1 ml of the solution. We need to find quantity required for a 0.125 mg dose.
This can be found using unitary method.
For 0.05 mg, the quantity required is = 1ml
Thus for 1 mg , the quantity required is = [tex]\frac{1}{0.05}\times 1=20ml[/tex]
For 0.125 mg , the quantity required is = [tex]\frac{20}{1}\times 0.125=2.5ml[/tex]
Thus quantity required for a 0.125 mg dose is 2.5 ml
