Basic Drug Calculations: Problem 4

The physician orders Lasix 20 mg IV stat for a child weighing 34 lbs. The pediatric handbook states that 1 mg/kg is a safe initial dose.  Should you give this dose?

  34 lbs. X   1kg/2.2 lbs = 15.5 kg

15.5 kg X 1 mg/kg = 15.5 mg

The does is too high, you need to call the physician.
