# The medication order is dosed at 0.5 mg/m per day. The pediatric

The medication order is dosed at 0.5 mg/m per day. The pediatric patient is 34 inches in height and weighs 32 lb. What is the recommended dose for this patient?

Hello,

I want to confirm if the medication order is in mg/m2

Customer: replied 3 years ago.

yes, it's the m with the small 2 at the top

OK

Now it clears the confusion.

BSA (m²) = ( [Height(cm) x Weight(kg) ]/ 3600 )½ e.g. BSA = SQRT( (cm*kg)/3600 )

or in inches and pounds: BSA (m²) = ( [Height(in) x Weight(lbs) ]/ 3131 )½

Here 1/2 means SQRT

Based upon this formula body surface area of patient is 0.59 m2

Calculations

32/34=1088/3131=0.347 SQRT=0.59

How to calculate SQRT

Now dose is 0.5mg/m2/day

Calculate the dose in mg: 0.5 mg/m2 × 0.59 m2 = 0.295mg per day
