Hey, I need some help with pediatric dosage calc. I have two teachers that solve this problem differently and now I am confused and frustrated?
Doctor orders: Haldol (Haloperidol) 1 mg IM
Available: 50 mg/10 ml. Multidose vial, the young boy is 11 years old.
Teacher A) *uses Young formula*
step 1: 11/11+12x1mg= 0.47826087mg
step 2: 0.47826087mg/50mgx10ml= 0.09 mL
Answer: 0.09 mL
Teacher B) *says young formula is not applied*
1mg/50mgx10mL= 0.2 mL
Answer: 0.2 mL
So, is "Teacher A" correct or "teacher B"??

Always look at what the question is asking you
If the order is for 5mg of drug X per kg and the child is 10kg, what dose will you administer.
it makes sense to do the following
5mg X 10kg = 50mg.
if you then have a question If the order is for 5mg of drug X per kg and the child is 10kgs you have solution 100mgs in 5mls how much would you administer
you could do
5mg X 10kg =50mg
50/100 X 5mls= 2.5mls
I reccomend the book Maths and Meds for nurses, it taught me the whole drug calculation route from adults to kids
