A prescriber has ordered medication for a newborn that is eliminated primarily by hepatic metabolism. What would the nurse expect the prescriber to order?
A Increase the frequency of medication dosing.
B Order a dose that is higher than an adult dose.
Discontinue the drug after one or two treatments.
D Order a dose that is lower than an adult dose.
The Correct Answer is D
a) Increasing the frequency of medication dosing may lead to higher overall exposure and is not necessarily related to hepatic metabolism.
b) Ordering a dose that is higher than an adult dose could result in excessive drug levels, especially in a newborn with immature hepatic function.
c) Discontinuing the drug after one or two treatments may not be necessary if the dose is appropriately adjusted based on hepatic metabolism.
d) Ordering a lower dose is appropriate because hepatic metabolism in newborns is often immature, and lower doses are required to avoid toxicity.
