Question

a child is ordered 0.3 g of a medication ivpb q8h. the child weighs 55 lbs. the recommended dosage of this medication is 30 - 70 mg\kg\\24h. how many mg is the child receiving each day? mg (if decimal, round to the tenth place.) what is the low recommended dose for this child per day? mg/day (if decimal, round to the tenth place.) what is the high recommended dose for this child per day? mg/day (if decimal, round to the tenth place.) is this order safe and therapeutic? (enter 1 for yes or 0 for no)

Explanation:

Step1: Convert weight from lbs to kg

Since \(1\) kg \( = 2.2\) lbs, the child's weight \(w=\frac{55}{2.2}=25\) kg.

Step2: Calculate the amount of medication received per day

The child is given \(0.3\) g every \(8\) hours. There are \(24\) hours in a day, so the number of doses \(n = \frac{24}{8}=3\). Since \(1\) g \(= 1000\) mg, \(0.3\) g \(=0.3\times1000 = 300\) mg per dose. The total per day \(=300\times3=900\) mg.

Step3: Calculate low - recommended dose

The low - recommended dose is \(30\) mg/kg/day. For a \(25\) kg child, \(d_{low}=30\times25 = 750\) mg/day.

Step4: Calculate high - recommended dose

The high - recommended dose is \(70\) mg/kg/day. For a \(25\) kg child, \(d_{high}=70\times25=1750\) mg/day.

Step5: Check if the order is safe

Since \(750\lt900\lt1750\), the order is safe.

Answer:

• \(900\) mg
• \(750.0\) mg/day
• \(1750.0\) mg/day
• \(1\)
