A nurse is collecting a blood phenylketonuria (PKU) test for a newborn prior to discharge.The newborn's guardian asks the nurse what a positive PKU test would mean.
Which of the following statements should the nurse make?
A positive finding indicates the inability to metabolize galactose.
A positive finding indicates the infant will have a slow metabolism.
A positive finding indicates an inability to metabolize certain amino acids.
A positive finding indicates an increased risk for neurological anomalies.
The Correct Answer is C
Choice A rationale
A positive finding for galactosemia, not PKU, indicates the inability to metabolize galactose. Galactosemia is a different metabolic disorder that requires a separate dietary intervention.
Choice B rationale
A positive PKU test does not indicate slow metabolism. Instead, it signifies the inability to metabolize phenylalanine, an amino acid.
Choice C rationale
Phenylketonuria (PKU) is a genetic disorder that leads to the inability to break down the amino acid phenylalanine. Without proper management, it can accumulate in the body and cause brain damage and other health issues.
Choice D rationale
A positive PKU test is not directly linked to an increased risk for neurological anomalies in general. The specific issue in PKU is the inability to metabolize certain amino acids, primarily phenylalanine, which can cause neurological damage if untreated. .

Correct Answer is B
Explanation
Choice A rationale
Cesarean birth is not necessarily required for GBS-positive clients as long as IV antibiotic prophylaxis is administered during labor to prevent transmission to the newborn.
Choice B rationale
IV antibiotic prophylaxis, typically with penicillin or ampicillin, is given to GBS-positive clients during labor to prevent neonatal GBS infection.
Choice C rationale
Obtaining a vaginal culture at 39 weeks of gestation is not necessary if the client was already screened and found positive for GBS at 36 weeks.
Choice D rationale
Metronidazole is used to treat bacterial vaginosis or trichomoniasis, not GBS infection; thus, it is not appropriate for this scenario. .
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"A"},"F":{"answers":"B"},"G":{"answers":"A"}}
Explanation
- Administration of IV fluids: This is anticipated as it ensures the client remains well-hydrated, which is important for both maternal and fetal health.
- Continuous monitoring of FHR: This is anticipated to monitor the fetal well-being and ensure there are no signs of fetal distress.
- Abdominal ultrasound: This is anticipated to assess fetal growth, amniotic fluid levels, and placental positioning.
- Digital cervical exam to assess dilation and effacement: This is contraindicated because frequent cervical exams can increase the risk of infection and may cause unnecessary discomfort, especially if there are no signs of labor.
- Laboratory testing: CBC, Blood Type & Rh, Coagulation Studies: These tests are anticipated to provide important information about the client's blood count, blood type, Rh status, and coagulation parameters, which are crucial for managing potential complications.
- Placement of an internal fetal spiral electrode: This is contraindicated as it is an invasive procedure that carries risks, and it is unnecessary given that the FHR is within normal limits with external monitoring.
- Administration of betamethasone: This is anticipated as betamethasone is often given to promote fetal lung maturity in cases where there is a risk of preterm birth.
