A child with a heart defect, weighing 19 pounds
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: 0.30 mg/dose
Rationale: The correct answer is 0.30 mg/dose.
To calculate this, first convert the child's weight in pounds to kilograms (19 lbs / 2.2 = 8.64 kg).
Then, multiply the weight by the prescribed dose (0.07 mg/kg/day x 8.64 kg = 0.6048 mg/day). Since the total daily dose is divided into two doses, each dose should be half of the total daily dose (0.6048 mg/day / 2 = 0.3024 mg/dose, rounded to 0.30 mg/dose). This ensures that the child receives the correct amount of medication in each dose.
Choice A and other options are incorrect because they do not follow the correct dosage calculation based on the child's weight and the prescribed dose.
