You receive an order for Ceftriaxone 125 mg IM if you use ceftriaxone 1g / 9.6 ML to fill the order how many ML draw up

The ML draw up = 1.2 ML

Step-by-step explanation:

we are told that concentration of Ceftriaxone = 1g / 9.6ML

This means that:

9.6 ML contains 1g ceftriaxone

1g = 9.6 ML

note also that 1g = 1000mg

∴ 1000mg = 9.6 ML

∴ 1mg = (9.6 : 1000) ML

1mg = 0.0096 ML

∴ 125 mg = 125 * 0.0096 = 1.2 ML

Therefore, 1.2 ML will be drawn up
