Question 1 of 5
A nurse is preparing to administer digoxin at a dosage of 8 mcg/kg/day orally, divided equally every 12 hours, to a preschooler who weighs 33 lbs. Digoxin elixir is available at a concentration of 0.05 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.)
Correct Answer: 1.2
Rationale: Calculation: 33 lbs ÷ 2.2 = 15 kg; 15 kg × 8 mcg/kg/day = 120 mcg/day; 120 mcg ÷ 2 = 60 mcg/dose; 60 mcg = 0.06 mg; 0.06 mg ÷ 0.05 mg/mL = 1.2 mL
