Question

a 60 lb child is to receive gentamicin. the recommended dose for children is 32mg/kg. what is the recommended dose for this child? if 1 tablet is triturated to make 15 mg compound, how many tablets need to be triturated to make 90 mg compound

Explanation:

Step1: Convert lbs to kg

1 lb = 0.453592 kg, so $60 \times 0.453592 = 27.2155$ kg

Step2: Calculate gentamicin dose

Multiply weight by dose per kg: $27.2155 \times 32 = 870.896$ mg

Step3: Find number of tablets

Divide total mg by mg per tablet: $\frac{90}{15} = 6$

Answer:

1. The recommended gentamicin dose for the child is 870.9 mg (rounded) or 870.896 mg
2. 6 tablets need to be triturated to make 90 mg compound
