A nurse is preparing to administer a dexamethasone 1.5 mg/kg/day PO to divide equally every 6 hr to a preschool-age child who weighs 22 lb. Available is dexamethasone oral solution 1 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. use a leading zero if it applies. Do not use a trailing

Step 1 is to convert pounds to kilograms: (22 ÷ 2.2) = 10 Result = 10 kg Step 2 is to calculate the total daily dose in mg: 10 × 1.5 = 15 Result = 15 mg/day Step 3 is to determine the number of doses per day when given every 6 hours: 24 ÷ 6 = 4 Result = 4 doses/day Step 4 is to divide the total daily dose by number of doses: 15 ÷ 4 = 3.75 Result = 3.75 mg per dose Step 5 is to calculate volume in mL: (3.75 ÷ 1) = 3.75 Result = 3.75 mL Step 6 is to round to the nearest tenth: 3.75 rounds to 3.8
