Question

An infant who weighs 4.6kg has an order for digoxin solution, 20 mcg PO BID. The drug reference states that a safe dosage range is 6-10 mcg/kg/ dose oral daily in 2 divided doses. Digoxin solution contains 0.05 mg/ 1 mL. What is the minimum recommended dosage range for this child per dose?

Answer 1

To find the minimum recommended dosage range of digoxin for the infant, we calculate the weight-based dosage by converting the weight to grams and multiplying it by the lower end of the safe dosage range.

Step-by-step explanation:

The infant weighs 4.6kg and needs a digoxin dosage of 20 mcg PO BID. The safe dosage range for digoxin is 6-10 mcg/kg/dose daily in 2 divided doses. To find the minimum recommended dosage range for this child per dose, we need to calculate the weight-based dosage.

First, we'll convert the weight of the infant to grams by multiplying 4.6kg by 1000. This gives us 4600g.

Next, we'll calculate the minimum recommended dosage range by multiplying the weight in grams (4600g) by the lower end of the safe dosage range (6 mcg/kg/dose). This gives us 27,600 mcg.
