Question

How many milliliters of this suspension should be given to an infant weighing 23 lb ? (assume two significant figures.) express your answer using two significant figures?

Answer 1

Answer;

= 5.2 mL

Explanation;

100 mg / 5.0 mL  

so 10 mg / 0.5 mL  

so dose is 0.5 mL / kg  

23 lb x (1 kg / 2.21 lb) x (0.5 mL x 1 kg) = 5.2 mL  

Baby dose is 5.2 mL
