A nurse is preparing to administer dicloxacillin 6.25 mg/kg PO to a child who weighs 14 lb. Available is dicloxacillin 62.5 mg/5 mL. How many ml should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the dosage of dicloxacillin to administer to the child, we need to follow these steps Convert the child's weight from pounds to kilograms: 1 pound (lb) = 0.453592 kilograms (kg) Child's weight in kg = 14 lb × 0.453592 = 6.35 kg Determine the dose in mg: Dosage required = 6.25 mg/kg Dose = 6.25 mg/kg × 6.35 kg = 39.6875 mg Determine how many mL of the medication to administer: The concentration of dicloxacillin is 62.5 mg/5 mL Using the formula: Volume (mL)= Dose (mg)/Concentration (mg/mL) Concentration (mg/mL) = 62.5 mg / 5 mL = 12.5 mg/mL Volume (mL) = 39.6875 mg / 12.5 mg/mL = 3.175 mL Round to the nearest tenth: Volume to administer = 3.2 mL The nurse should administer 3.2 mL of dicloxacillin.
