To find the needed volume, use Volume = Dose / Concentration. First determine the total dose: 22 kg × 1 mg/kg = 22 mg. The drug is 10 mg per mL, so each mL contains 10 mg. Divide the total dose by the concentration: 22 mg ÷ 10 mg/mL = 2.2 mL. So, to deliver 22 mg, you would administer 2.2 mL. (For context, 2.0 mL would provide 20 mg, 1.0 mL would provide 10 mg, and 3.0 mL would provide 30 mg.)
