Question 1 of 5
To maintain patency of the ductus arteriosus, the nurse administers a prescribed dose of prostaglandin intravenously (IV) to a week-old infant diagnosed with transposition of the great vessels. Based on which finding should the nurse stop the medication administration immediately?
Correct Answer: A
Rationale: A heart rate of 50 beats/minute indicates bradycardia, a serious adverse effect of prostaglandin, requiring immediate cessation of the medication.
Question 2 of 5
When administering indomethacin to a premature infant who has patent ductus arteriosus, the nurse should anticipate which outcome?
Correct Answer: C
Rationale: Indomethacin promotes closure of the patent ductus arteriosus, reducing the cardiac murmur associated with the abnormal blood flow.
Question 3 of 5
The nurse is providing education to a new parent on the potential causes of developmental dysplasia of the hip and recommendations to decrease the incidence in infants. Which statement made by the parent should the nurse recognize as understanding the education?
Correct Answer: D
Rationale: Holding the infant with legs widely spread apart allows natural hip flexion and abduction, reducing the risk of developmental dysplasia by preventing adduction.
Question 4 of 5
A healthy 2-day-old newborn received the first dose of hepatitis B prior to being discharge home with the parents. The nurse should instruct the parents to return to the clinic for the infant's next dose of hepatitis B in how many months?
Correct Answer: D
Rationale: The hepatitis B vaccine schedule for infants involves three doses, with the second dose administered 1 to 2 months after the first, ensuring timely immunity development. The 2-month interval is appropriate for the next dose.
