This isn't homework, these are practice questions that I am trying to figure out. School hasnt started as yet so I dont have any homework. I know how to set up the problem but I am stumped at the gm/ml. So far I have 1 dose = 40lbs/4 doses x 1 kg/2.2lbs x 150mg/1kg now I am not sure whether I should then put 1gm/1000 mg x 5ml/0.5gm. Please help someone! I know that this is my work and my responsibilty, but I am just asking for some assistance in figuring out this problem. Some of you nurses on here are so unhelpful and feel as though us students just want a handout when most times we are just asking for help just like how you needed help when in nursing school. Its sad to see this.
I am practicing ped dose cal for when school opens next month and have been stomped on this question for an hour now and still trying to figure it out. PLEASE HELP!The recommended dose of Gantrisin Pediatric Suspension is 150 mg/Kg PO in 4 doses daily
Gantrisin Pediatric Suspension 0.5 Gm/5ml
How many ml should be given for one dose for a 40 lb child
I will be soo grateful.
40 pounds divided by 2.2= 18.2 kg
150mg x 18.2 kg=2730 mg (for whole day)
2730mg divided by 4 doses =683 mg/dose
1GM/10cc (I always round to 1 when I can)...or- .100mg/1cc
For 683mg, you need 6.8cc
Any others, if I made a mistake, let me know :)

I got the same answer. Ofcourse I had to do mine the long way but, there are several ways to get to grandmas house.
The only thing I did different was to convert mg to grams. I converted 683mg to 0.683 GM. Then I did 0.683GM X 5ML / 0.5GM which is 6.8 cc.
Don't forget to always convert, a lot people forget to convert lbs to KG and other conversions. When I take my Calc exams I always break up the problem ( see below), I use this format and have gotten A's on these exams.
Break down of problem:
1. Write out the order
2. Write what is available
3. Write what conversions are needed to solve the problem. EX. lbs to kg or mg to Gm
4. Write what is the question asking for
5. Set up problem. Put order over what is on hand then proceed with any conversions needed. Make sure all units cancel out so that you end up with units needed. If answer asks for ml/hr make sure you have that in your answer.
Good luck.
