Dosage Calc question...Caluculating mg/m2...
- 0Jan 13, '13 by Katie71275, ASN, RNOK the question is:
A med is ordered 2mg/m2 for a child who weighs 50lbs and is 43 inches tall. Calculate the dosage.
So this is what I've got:
43x50/3131 and then sq rt is which is 0.83m2. Multiple 0.83m2 x 2mg=1.66mg.
The instructors answer is 1.17mg. Myself and another student have both gotten 1.66 and not sure where the 1.17mg came from....Anyone want to help? Is the 1.66 right and instrucotrs 1.17 wrong or did we miss a step?
