First, use the equivalent: 1 kg = 2.2 lb. Convert pounds to kilograms by dividing the number of pounds by 2.2: 44/2.2 = 20 kg. Determine the safe range of dosage. Low dose: 6.7 mg × 20 kg = 134 mg; high dose: 13.3 mg × 20 kg = 266 mg. The safe range is 134 to 266 mg, q8h. The dose ordered (100 mg, q8h) is safe. Use the Formula Method to determine milliliters to be given for each dose: 100 mg/125 mg × 5 mL: 500/125 = 4 mL.
