A child who weighs 16 pounds receives a prescription for amoxicillin 25 mg/kg/day by mouth in divided doses every 12 hours. The bottle is labeled, 'Amoxicillin for Oral Suspension, USP 200 mg per 5 mL.' How many mL should the nurse administer with each dose? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct answer
A
Rationale
Step 1: Convert 16 pounds to kilograms: 16 ├â┬À 2.2 = 7.3 kg. Step 2: Calculate total daily dose: 25 mg/kg ├âÔÇö 7.3 kg = 182.5 mg. Step 3: Divide by 2 for every 12-hour dose: 182.5 mg ├â┬À 2 = 91.25 mg. Step 4: Convert to mL: 91.25 mg ├â┬À (200 mg/5 mL) = 91.25 ├â┬À 40 = 2.3 mL per dose.
