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.)

  • A. 3.8 mL
  • B. 2.8 mL
  • C. 4.8 mL
  • D. 1.8 mL
Correct Answer: 3.8

Rationale: Calculation: 22 lb ÷ 2.2 = 10 kg; 1.5 mg/kg/day × 10 kg = 15 mg/day; 15 mg ÷ 4 doses = 3.75 mg/dose; 3.75 mg × 1 mL/1 mg = 3.8 mL.
