Explanation
•Drug addicted newborns usually experience drug withdrawal symptoms beginning 24-48 hours birth (but it may take up to a week for symptoms to appear). This includes low birth weight, nervousness, irritability, seizures, poor feeding, piercing cry, and respiratory distress.
•Illicit drugs tend to be of small molecular weight, so they cross the placenta readily. As a result, the fetus of an addicted mother has a drug concentration of about 50% that of the mother.
•Other choices are incorrect, infants usually appear lethargic and irritable.
