Drug Dilution Calculation correct answer: Drug % x 10 = number of mg in 1 mL of the drug. Step 1: drug % x 10 = # mg/mL. Step 2: # mg/mL x dosage ordered = number of mg of drug How many mg are in 3.0 mL of a 0.083% solution? correct answer: Step 1: 0.083 x 10 = 0.83 mg/mL. Step 2: 0.83 mg/mL x 3 mL = 2.5 mg Respiratory therapist is asked to administer 2.5 mg of Albuterol. medication is available in a 0.5% solution.
