An antibiotic is reconstituted with 128ml of water to yield 250mg/5ml.

Question

A) If the child weighs 66 pounds what will the dose be at 5mg/kg/dose?
B) If the medication is given qid x 10 days, will the 150ml bottle be enough?

Answer 1

You need to convert pounds to kg to solve A. Then multiply it by the 5 mg to get total mg/dose.

250mg/5ml = total mg/?ml for A.

150/(total[?] ml*4*10) will answer B.

I hope this helps. Thanks for asking.
