A nurse in the newborn nursery is caring for an infant who has trisomy 21. When collecting data, which of the following findings should the nurse expect?
A single crease in the palm.
A notch in the lip.
An inversion of the foot.
Extra digits on the hand.
The Correct Answer is A
Choice A rationale
A single crease in the palm, known as a simian crease, is a common characteristic seen in infants with trisomy 21 (Down syndrome) due to the unique hand structure associated with this condition.
Choice B rationale
A notch in the lip, such as a cleft lip, is not commonly associated with trisomy 21 and is more typically related to other genetic conditions or environmental factors during development.
Choice C rationale
An inversion of the foot, such as clubfoot, is not a specific characteristic of trisomy 21. This condition is more often seen in other congenital anomalies not related to Down syndrome.
Choice D rationale
Extra digits on the hand, or polydactyly, is not commonly associated with trisomy 21 but can be seen in other genetic disorders. Trisomy 21 has more specific physical features like the simian crease.

Correct Answer is A
Explanation
Choice A rationale
Testing for GBS at around 36 weeks of gestation is standard practice to identify carriers and prevent neonatal GBS infections through intrapartum antibiotic prophylaxis if necessary.
Choice B rationale
Cesarean birth is not indicated solely based on a positive GBS status. The primary intervention is intrapartum antibiotic prophylaxis to reduce the risk of neonatal infection.
Choice C rationale
Routine antibiotic administration during the last weeks of pregnancy is not standard practice; antibiotics are given during labor if GBS is present to prevent transmission to the baby.
Choice D rationale
GBS infection does not cause hearing loss in newborns. The primary concern is neonatal sepsis, pneumonia, or meningitis, not hearing loss.
Correct Answer is D
Explanation
Choice A rationale
This statement is incorrect because after a cesarean birth, clients are usually started on clear liquids and then gradually progress to regular food as tolerated. Swallowing safety is related to anesthesia recovery, not cesarean birth recovery.
Choice B rationale
This statement is incorrect because the client does not need to stay flat on their back for 24 hours. Early ambulation is encouraged to prevent complications such as deep vein thrombosis and promote recovery.
Choice C rationale
This statement is incorrect because the urinary catheter is typically removed within 24 hours after surgery to reduce the risk of urinary tract infections and encourage normal bladder function.
Choice D rationale
This statement is correct because after a cesarean birth, the nurse will frequently assess the uterus for firmness and massage it as needed to prevent postpartum hemorrhage.
