The nurse is preparing to administer the daily maintenance dose of digoxin to an infant:
Infant's Weight: 5kg
Order: Administer 4mcg/kg/day
Safe Dose: 3.4 to 5.1 mcg/kg/day
Label: 0.25 mg/5mL
The Correct Answer is ["0.4"]
To calculate the daily maintenance dose of digoxin for the infant, we first convert the ordered amount from micrograms to milligrams: 4 mcg/kg/day is equivalent to 0.004 mg/kg/day. For an infant weighing 5 kg, the daily dose would be 0.004 mg/kg/day * 5 kg = 0.02 mg/day. Now, using the concentration provided on the label, which is 0.25 mg/5 mL, we can find out how many milliliters would equate to the required daily dose. This is done by setting up a proportion: (0.25 mg / 5 mL) = (0.02 mg / X mL). Solving for X gives us X = (0.02 mg * 5 mL) / 0.25 mg, which equals 0.4 mL.

C. Side-lying with head slightly elevated is also not ideal as it can lead to pressure on the sac.
D. Prone with hips flexed and legs abducted is the best position to avoid pressure on the myelomeningocele sac, prevent trauma, and reduce the risk of infection before surgical repair.
