Child's dose math/ tablets (2)

I don't even understand where to begin! lol

1)A child's dose for cefadroxil is 30 mg/kg body weight once a day for 14 days. What is the smallest bottle that will provide enough medication to last 14 days if the child weighs 44 pounds?

2)The doctor changes a prescription for 150 ml of amoxicillin 250 mg/ 5 ml to 250 mg chewable tablets. How many many chewable tablets should be dispensed?

I'm sure I'm just confusing myself... I was thinking 30 for the second answer by dividing 250 mg by 5 ml and I was right, but I just wanted make sure I was doing it the right way.

 Dec 22, 2011 Rx Dosage by: Az First kg to pounds:44*0.454=19.9761. Its not kg to pounds but pounds to kg conversion.2. Never first divide 1/2.2 and get that .454 \instead do it like this44kg*1/2.2lbs = 20kg get a clean cut figure of 20kg and not 19.976.3. Your final answer will be 8400mg not what u have.

 Aug 06, 2011 30 TABS by: Anonymous It is wrong way. First, 150ml contain 7500mg amoxicillin. 250*150/5=7500mg.7500mg/250mg/tab= 30tabs
