    Calculation

    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 zero.)

    mL

    Explanation & Rationale

    Step 1: lb ÷ (2.2 lb/kg) = 10 kg. Step 2:.5 mg/kg/day × 10 kg = 15 mg/day. Step 3: mg/day ÷ 4 doses/day = 3.75 mg/dose. Step 4:.75 mg ÷ 1 mg/mL = 3.75 mL per dose. The calculated answer is 3.8 mL (rounded to the nearest tenth).
