Answer 1

Order: Valproic acid oral solution PO 15 mg per kg per day in two divided doses for a

pediatric patient who weighs 66 lb.

Available: Valproic acid oral solution 250 mg per 5 ml

250mg/5 ml

= 50mg/ml

kilograms the child weighs; = 66 lb/ 2.205

= 29.9371 kg

Milligrams per day should the child receive;

15 mg per kg per day

= 15 x 29.9371

= 449.0565 mg per day

milligrams per dose should the child receive; 449.0565/2

= 224.528 mg per dose

Millilliters per dose should the child receive; = 224.528/50 = 4.49056 ml
