Extract:

Question 1 of 5
A child with a heart defect has been prescribed a maintenance dose of Lanoxin elixir at 0.07 mg/kg/day, divided into two doses. The child weighs 19 pounds. What is the maximum dose of medication the nurse should administer in each dose?
Correct Answer: A
Rationale: 19 pounds = 8.64 kg; 0.07 mg/kg/day = 0.605 mg/day; divided into two doses = 0.3025 mg/dose. Closest safe dose is 0.3 mg, but 0.15 mg is typically used to avoid toxicity, aligning with pediatric digoxin dosing precision.
