Answer:
Correct choice is C. 2 mL.
Step-by-step explanation:
Given that Ampicillin 250 mg IM every 12 hours is ordered. After reconstitution, there's 125 mg/mL. Now we need to find about how many mL would you give.
Let number of ml needed = x.
Since ratio of mg per mL will be fixed so we get equation:
[tex]\frac{mL}{mg}=\frac{x}{250}=\frac{1}{125}[/tex]
[tex]\frac{x}{250}=\frac{1}{125}[/tex]
[tex]x=\frac{1}{125} \times 250[/tex]
[tex]x=\frac{250}{125}[/tex]
[tex]x=2[/tex]
Hence correct choice is C. 2 mL.
