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"??
