Question

a child is receiving 0.08 g of an antibiotic po q6h. the child weighs 6 kg. how many mg\kg\day is the child receiving? mg\kg\day (if decimal, round to the tenth place.)

Explanation:

Step1: Convert grams to milligrams

Since \(1g = 1000mg\), then \(0.08g=0.08\times1000 = 80mg\) per dose.

Step2: Calculate the number of doses per day

The dose is given every \(6\) hours (\(q6h\)). There are \(24\) hours in a day. So the number of doses per day \(n=\frac{24}{6}=4\) doses.

Step3: Calculate the total milligrams per day

The total milligrams per day \(=80mg\times4 = 320mg\)

Step4: Calculate milligrams per kilogram per day

The child weighs \(6kg\). So \(mg/kg/day=\frac{320mg}{6kg}\approx53.3mg/kg/day\)

Answer:

\(53.3\)
