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?
Correct answer
B
Rationale
Step 1: 22 lb ├â┬À 2.2 lb/kg = 10 kg. Step 2: 1.5 mg/kg/day ├âÔÇö 10 kg = 15 mg/day. Step 3: 15 mg/day ├â┬À 4 doses/day = 3.75 mg/dose. Step 4: 3.75 mg ├â┬À 1 mg/mL = 3.75 mL, rounded to 3.8 mL.
