So I'm working with my virtual ATI coach for my NCLEX and I'm currently on pediatrics. I have a medication calculation that I'm stumped on and after reviewing my medication administration textbook, I'm still not getting this question. Can someone help me with this? Thank you so much
" A nurse is preparing to administer ampicillin 25mg/kg PO divided in equal doses every 12 hours to an adolescence who weighs 99 lbs. The amount available is ampicillin suspension 50mg/5ml. How many mL should the nurse administer per dose? Round to nearest whole number. 56ml
After converting from 99 lbs to kg I got 45kg.
I then multiplied 25mg by 45kg and got 1125mg/45kg.
I then divided the 1125 mg by 2 since this med is taken every 12 hours in equal doses.
I got 562.5mg per dose.
The med is available in 50mg/5ml, so I divided 562.5 by 50mg ad got 11.25.
Last I multiplied 11.25mg by 5ml and got 56.25
Then rounded down to 56ml.
This does;t look right but I can't figure out where I went wrong. Please help!
