Question

Order received: Chloromycetin 30 mg/kg/day to be given in divided dosages q8 hrs. Tyler weighs 28 pounds. How many mg should he receive in one day? _______ How many mg should he receive per dose? ________

Answer 1

Ordered Chloromycetin=30mg/kg/day in divided dosages q8 hours

Wt of patient=28 pounds= 12.72 kg

Then dose as per weight of patient=30X12.72= 381.6 mg per day

Then per dose the patient will receive=381.6/3

=127.2 mg

Because q8h means every 8 hours means one third of the per day dose here
