First, you need to convert all units to calculate what dose the doctor ordered.

1 dram = 4 mL
So, it must be given 4 mL of medication

1 cc = 1 mL
So, if t<span>he vial states that there is 1 mg in 1 cc </span>, that means the concentration is 1 mg in 1 mL or, 1 mg/mL.

Now, we need to calculate what is the dose of medication in 4 mL:
1 mg is in 1 mL, how many mg is in 4 mL:
1 mg : 1 mL = x : 4 mL

Crossing the products:
x · 1 = 1 mg · 4
⇒ x = 4 mg
