A 46 lb child is prescribed 1 Tsp of medicinal syrup three times a day. There are 2 mg of medicine per 5 ml of syrup, and a safe dose is 0.1 mg per kg of body weight. Is the prescribed dose safe?

• 1 Tsp 3 times a day=3 Tsp per day
  1 Tsp= 15 ml, so that's 45 ml per day
  5 ml=2 mg, so 45 ml = 45/5 X 2, =18 mg per day
  18 mg in a 46 lb child is 18/46=0.391 mg per 1 lb
  454 grams = 1 lb
  We now have 0.391 mg/454g
  1000g=1 kg
  Dosage is 0.391 X 1000 / 454
  =0.86mg per kg of body weight
  Safe dosage= 0.1mg/kg of body weight
  Not safe.
