A nurse is preparing to administer a medication to a client who weighs 55 kilograms. The prescription is for 2 mg/kg/day, to be administered in two equally divided doses. How many milligrams should the nurse administer for each dose?
45 mg
55 mg
110 mg
27.5 mg
To calculate the correct dosage, first determine the total daily dose: 55 kg × 2 mg/kg = 110 mg/day. Since the medication is to be given in two divided doses, divide the total daily dose by two: 110 mg ÷ 2 = 55 mg per dose. Therefore, the nurse should administer 55 mg for each dose. Administering 110 mg would be the total for the entire day, not a single dose. 45 mg and 27.5 mg are incorrect calculations.
