Question 1 of 5
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 ÷ 2.2 lb/kg = 10 kg.
Step 2: 1.5 mg/kg/day × 10 kg = 15 mg/day.
Step 3: 15 mg/day ÷ 4 doses/day = 3.75 mg/dose.
Step 4: 3.75 mg ÷ 1 mg/mL = 3.75 mL, rounded to 3.8 mL.
