Use the equivalent: 1 kg = 2.2 lb. Convert pounds to kilograms by dividing the number of pounds by 2.2: 22/2.2 = 10 kg. Determine the safe dosage. The literature states the recommended single dose of 2 mg/kg. A 10 kg child would receive 20 mg (2 mg × 10 kg). Formula Method: 20mg/10 mg × 1 mL; 20/10 = 2 mL. Give 2 mL of a single dose of 20 mg.
