A child weighing 15 kg is prescribed a drug at 40 mg/kg/day divided into 2 equal doses. How many mg should each dose contain?
Answer and explanation
Correct answer: A. 300 mg
- Step 1: Daily dose = 40 x 15 = 600 mg.
- Step 2: Each dose = 600 / 2 = 300 mg.
Answer
300 mg.
Why not the others: 600 mg is the whole daily dose; the other values ignore the weight or multiply instead of dividing.
