The healthcare provider prescribes amoxicillin 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled, "Amoxicillin suspension 200 mg/5 mL." How many mL should the nurse administer every 8 hours? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Calculate the total daily dose in milligrams: Total daily dose (mg) = Prescribed dose (grams) x 1000 mg/gram = 1.5 grams x 1000 mg/gram = 1500 mg Determine the number of doses per day: Number of doses per day = 24 hours / Frequency of doses (hours) = 24 hours / 8 hours/dose = 3 doses/day Calculate the dose to administer every 8 hours: Dose per administration (mg) = Total daily dose (mg) / Number of doses per day = 1500 mg / 3 doses = 500 mg Calculate the volume to administer per dose in mL: Volume per dose (mL) = Desired dose (mg) / Available concentration (mg/mL) = 500 mg / (200 mg / 5 mL) = 500 mg / 40 mg/mL = 12.5 mL The nurse should administer 12.5 mL every 8 hours.
