What is the equivalent number of grams?

Question

While still in the hospital, the doctor writes an order for an antibiotic at 250mg/kg/day. You are nervous now because the nurse was wrong before. Assuming that you weigh 158 lb, determine how many milligrams should you be given. What is the equivalent number of grams? (Hint: 1000 mg = 1 g and mg/kg/day = )

Answer 1

158/2.2 = 72 kg

72(250) = 18,000 mg/day

18,000/1000 = 18 g
