Question

1/h tablet8 18. A 14-year-old is diagnosed with depression. The healthcare provider prescribes trazadone (Desyrel) 2 mg/kg PO 3 times a day. The person weighs 124 pounds. What is the amount of medication the patient will receive per dose (mg)? (Round to nearest tenth)

pounds must be converted to kilograms

Answer 1

Prescribed trazadone(Desyrel) = 2 mg/ kg PO 3 times a day

Patient weight = 124 lbs

To convert lbs to kgs divide the mass with 2.2

124 $\div$ 2.2 = 56.36 can be rounded to 56 kgs

56 kgs $\times$ 2 mg = 112 mg

Per dose the patient should be given 112 mg of trazadone. Per day 112 $\times$ 3 = 336 mg to be given each day.
