Question 1 of 5

A child who weighs 55 pounds receives a prescription for isoniazid 10 mg/kg/day by mouth (PO) once a day. The bottle is labeled, 'Isoniazid Oral Solution, USP 50 mg per 5 mL.'. How many mL should the nurse administer?

Correct Answer: 25

Rationale: Weight is 55 lbs ÷ 2.2 = 25 kg. Dosage is 10 mg/kg/day * 25 kg = 250 mg/day. Solution is 50 mg/5 mL, so 250 mg ÷ 50 mg * 5 mL = 25 mL.
