Pediatric dosage of a medication is 5

milligrams per kilogram every 4 hours. Calculate the daily dosage in milligrams

for a child weighing 60 pounds. To solve this problem the order needs to be

expressed in daily dosage in milligrams we’ll set that as our goal. To begin the

process we’ll start with the doctor’s order and in this particular problem the

amount of medication is based on the patient’s weight. To start the order then

to determine the correct amount of medication we will start with the

patient’s weight expressed here as a fraction with a denominator of 1 for an

equivalent value. The medication order, however is based on weight in the metric

system and we have weight in the English system this will require us to convert

from pounds to kilograms. There are 2.2 pounds equal to 1 kilogram.

Taking these equivalent values and placing the pound in the denominator and

the kilogram in the numerator will allow us to cancel out the common factor of

pounds and now with a weight of kilogram we can continue with the doctor’s order

of medication being administered at 5 milligram per kilogram every 4 hours.

which is shown here in our fraction. We have a common factor of kilogram we’ll

cancel out. Our units currently are in milligram per hour. The problem is asking

in the amount of dosage per day so our last conversion fraction we’ll need to

replace hours that are currently in the denominator. Every day consists of 24

hours taking these equivalent values and arranging them for our final conversion

fraction we have the follow allowing us to cancel out the common

factor of hours, leaving milligrams per day. Last step then will be to multiply

the fractions and then simplify with division for a final answer of 818.18

hundred’s. Since this is a pediatric dosage the

procedure is to truncate rather than round up and perhaps risk over

medicating the patient. To truncate this to the nearest tenth we will drop the

eight hundredths for the correct medication dose each of 818 and

one tenth milligram per day.
