I need help with this word problem.

Question

A hospital ordered: Promethazine 2 mg/kg of body weight. How many mgs should you give to a 42 lb. post-op child? Round to the nearest hundredth. (1 lb = 0.45 kg)

Answer 1

Convert the 42 pounds to kilograms then use that with the Promethazine dosage to get the amount.

Give it a try.
