Question

A pediatric patient weighing 66 lb is prescribed digoxin (Lanoxin) 12 mcg/kg in 3 evenly divided doses. How much will the nurse administer per dose?

a) 1 mcg/kg
b) 2 mcg/kg
c) 3 mcg/kg
d) 4 mcg/kg

Answer 1

The nurse will administer 356.4 mcg of digoxin per dose to the pediatric patient.

Step-by-step explanation:

The weight of the pediatric patient is given as 66 lb. In order to determine the dose of digoxin per kg, we need to convert the weight to kilograms. 1 lb is approximately 0.45 kg. So, 66 lb is approximately 29.7 kg.

The dose of digoxin is 12 mcg/kg per dose. Therefore, the nurse will administer 12 mcg of digoxin for every kilogram of the patient's weight. Since the weight of the patient is approximately 29.7 kg, the nurse will administer 12 mcg/kg x 29.7 kg = 356.4 mcg per dose.

Therefore, the nurse will administer 356.4 mcg of digoxin per dose.
