Question

The recommended pediatric dosage of Velosef is 25mg/kg/day. What is the daily dose, in mg, for a child weighing 55 lbs.? The stock vial of Velosef is labeled 225mg/mL. How many mL would be given in a daily dose? Use 1 kg = 2.2 lbs and round your final answer to 2 decimal place.

Answer 1

`\begin{gathered} 1kg=2.2lb \\ 55lb\ast(1kg)/(2.2lb)=25kg \\ Dosage=25\text{ mg/kg/day} \\ stoke\text{ vial=225mg/mL} \\ dosage\text{ in mg=\lparen25mg/kg/day\rparen\lparen25kg\rparen\lparen1day\rparen=625 mg} \\ 225mg/mL=(625mg)/(x) \\ x=number\text{ mL} \\ Solving\text{ x} \\ x=(625mg)/(225mg/mL) \\ x=2.78\text{ mL} \\ 2.78\text{ mL would be given ina daily dose} \end{gathered}`
