Question

The physician orders 10 mg of mafenide acetate applied to a burn twice daily. Available is 50 mg/15 mL. How many mL of mafenide acetate should you administer? Multiple Choice 15 mL 10 mL 7 mL 3 mL

Answer 1

Answer:

3 mL (twice daily)

Explanation:

The desired dosage equation can be computed using the formula:

$x = \dfrac{desired\;dosage\times Quantity}{Stock\;on\;hand}$

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:

$x = \dfrac{10mg\times 15mL}{50mg} = \dfrac{150mL}{50} = 3mL$

You can also do this by using the quantity/dose on hand as your conversion factor:

$10mg\times\dfrac{15mL}{50mg} = \dfrac{150mL}{50} = 3mL$
