The dose of a drug is 0.5 mg/kg. What dose should be given to a 6-year-old child who weighs 44 lb?
0.05g
0.003g
0.010g
0.033g
0.010g
Rationale: For a 44 lb. child, if the drug dose is 0.5 mg/kg, the following formula would be used to calculate the correct dosage: 0.5 mg / X mg = 2.2 lbs / 44 lbs. Therefore, X = (10)mg, which is equivalent to 0.010 grams. (The age of the child is not relevant).
