The physician orders furosemide (Lasix) 2 mg/kg/24 hours orally to a child weighing 26 kg. How much should you give in 4 equally divided doses? How much should you give in a 24-hour period?
2 mg X kg = dose in 24 hours
2 mg X 26 kg = 52 mg in 24 hours
52 divided by 4 doses = 13 mg per dose
You should give 13 mg per dose every 6 hours or in 4 divided doses.
