You have a 4 year old patient that requires 0.5 milligram per kilogram of Diphenhydramine (benadryl). Your patient
weighs 55 lbs. How many kilograms does this patient weigh? (1 kg = 2.2 lbs.)
Explanation: For every 1 kilogram you have 2.2 pounds if you multiply 2.2 with 25 it adds up to what is 55 pounds (hopefully this is the answer you were looking for!)
