Final answer:
c) within 24-72 hours after birth
Newborns delivered by mothers with narcotic addiction are most likely to show symptoms of withdrawal within 24-72 hours after birth, as the newborn adjusts to life outside of the womb.
Step-by-step explanation:
The symptoms of narcotic withdrawal in newborns delivered by mothers addicted to narcotics are most likely to be observed within 24-72 hours after birth. This time frame is critical as the newborn is adjusting to life outside of the womb and is no longer receiving the narcotic through the placenta. These withdrawl symptoms can include irritability, poor feeding, tremors, and, in severe cases, seizures. It is important for healthcare providers to closely monitor these infants and provide appropriate interventions to manage withdrawal symptoms.
