RN HESI Dosage Calculations II ( 55 Questions)
The healthcare provider prescribes amoxicillin 500 mg every 8 hours for a child who weighs 88 pounds. The recommended maximum safe dose is 50 mg/kg/24 hour. The available suspension is labeled, Amoxicillin Suspension 250 mg/5 mL. Based on this child weight, how many mL should the nurse administer ? (Enter numerical value only. (If rounding is required, round to the whole number.)
- To calculate the dose in mL, use the formula: Dose (mL) = Dose (mg) / Concentration (mg/mL)
- The child's weight in kg is 88 / 2.2 = 40 kg
- The maximum safe dose for the child is 50 x 40 = 2000 mg per day - The prescribed dose for the child is 500 x 3 = 1500 mg per day, which is below the maximum safe dose
- The dose in mL for each administration is 500 / (250 / 5) = 10 mL - The nurse should administer 10 mL of amoxicillin suspension every 8 hours
