Question

the nurse receives orders to administer digoxin 10 mcg/kg of digoxin elixir as a loading dose to a child. the child weighs 55 pounds. digoxin is available as an elixir of 50 mcg/ml. how many ml of the digoxin elixir should the nurse administer to the child? (enter numeric value only.)

Explanation:

Step1: Convert pounds to kg

Since $1 \text{ lb} = 0.453592 \text{ kg}$, for 55 lbs:
$55 \times 0.453592 = 24.94756 \text{ kg}$

Step2: Calculate total digoxin dose

Dose is $10 \text{ mcg/kg}$, so:
$24.94756 \times 10 = 249.4756 \text{ mcg}$

Step3: Find required elixir volume

Concentration is $50 \text{ mcg/mL}$, so:
$\frac{249.4756}{50} = 4.9895 \approx 5$

Answer:

$5$
