Answer:
3 mL (twice daily)
Explanation:
The desired dosage equation can be computed using the formula:
[tex]x = \dfrac{desired\;dosage\times Quantity}{Stock\;on\;hand}[/tex]
In this case, the desired dosage is 10 mg and the quantity is 15 m and the stock on hand is 50 mg. So just plug that in the equation:
[tex]x = \dfrac{10mg\times 15mL}{50mg} = \dfrac{150mL}{50} = 3mL[/tex]
You can also do this by using the quantity/dose on hand as your conversion factor:
[tex]10mg\times\dfrac{15mL}{50mg} = \dfrac{150mL}{50} = 3mL[/tex]
