A physician orders Lanoxin elixir qd for an 81-pound child based on 3.4 mcg/ kg/day. Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL. What volume should be administered per dose?

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily

Explanation:

The child weighs 81 pound. The weight of the child is needed to be converted from pound to kg.

1 kg= 2.2 pound

Therefore 81 pound = 81/2.2 kg = 36.8 kg

Since the child is to be administered bases on 3.4 mcg/ kg/day, the volume of Lanoxin elixir qd to be administered to the 81 pound (36.8 kg) in one day = 36.8 kg × 3.4 mcg/ kg/day = 125.12 ≅ 125 mcg

Lanoxin (digoxin) Pediatric Elixir is 50 mcg (0.05 mg)/mL, therefore 125 mcg = 125 mcg / 50 mcg/ml = 2.5 ml

Therefore 2.5 ml of Lanoxin (digoxin) Pediatric Elixir is to be administered to the child daily
