A child who weighs 25 kg receives a prescription for isoniazid 10 mg/kg/day by mouth 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: A
Rationale: For a 25 kg child, the dose is 250 mg/day (25 kg × 10 mg/kg). With a concentration of 50 mg/5 mL (10 mg/mL), the volume is 250 mg ÷ 10 mg/mL = 25 mL.
