A nurse is caring for a client who is receiving prenatal care and is at her 24-week appointment.
Which of the following laboratory tests should the nurse plan to conduct?
1-hour glucose tolerance test.
Rubella titer.
Sexually transmitted disease test (STI test).
Group B strep culture.
The Correct Answer is A
Choice A rationale
The 1-hour glucose tolerance test is typically performed between 24 and 28 weeks of gestation to screen for gestational diabetes. This screening involves measuring the client's blood glucose level one hour after consuming a 50-gram glucose load. A normal result is generally considered to be a blood glucose level below 130-140 mg/dL.
Choice B rationale
Rubella titer is usually assessed early in pregnancy, ideally during the first prenatal visit, to determine the woman's immunity to rubella. If the woman is not immune, vaccination is typically offered postpartum to prevent infection in subsequent pregnancies, as rubella infection during pregnancy can cause serious congenital defects.
Choice C rationale
Sexually transmitted disease testing is ideally conducted at the initial prenatal visit to identify and treat any infections early in pregnancy, reducing the risk of transmission to the fetus and other complications. While repeat testing may be indicated based on risk factors, it is not a routine test specifically scheduled for the 24-week appointment for all clients.
Choice D rationale
Group B Streptococcus (GBS) culture is typically performed later in pregnancy, usually between 35 and 37 weeks of gestation, to determine if the woman is colonized with GBS. This is important for intrapartum management to prevent neonatal GBS infection.

Correct Answer is C
Explanation
Choice A rationale
Hyperemesis gravidarum is severe nausea and vomiting during pregnancy, typically occurring in the first trimester. While amniocentesis can cause some discomfort, it is not a known risk factor for hyperemesis.
Choice B rationale
Proteinuria is the presence of protein in the urine, which can be a sign of preeclampsia, a condition that can occur later in pregnancy. Amniocentesis, usually performed in the second trimester, is not directly linked to causing proteinuria.
Choice C rationale
Amniocentesis is an invasive procedure that involves inserting a needle through the abdominal wall and uterus to withdraw amniotic fluid. This procedure carries a risk of bleeding or hemorrhage from the insertion site or within the uterus. Therefore, observing for signs of hemorrhage is a crucial nursing intervention post-amniocentesis.
Choice D rationale
Hypoxia is a condition of insufficient oxygen supply to the tissues. While complications of amniocentesis could indirectly lead to fetal hypoxia in rare cases (e.g., placental abruption), it is not a direct and common complication to observe for in the mother. Hemorrhage is a more immediate and direct risk for the mother. .

Explanation
Rationales for Each Condition
Neonatal Abstinence Syndrome (NAS)
- Temperature: Infants experiencing NAS often have difficulty regulating body temperature due to autonomic instability. While the newborn's temperature of 36.6°C (97.9°F) is within normal range, the use of a radiant warmer suggests challenges in maintaining thermoregulation, which is characteristic of NAS.
- Jitteriness: Jitteriness is observed in both hypoglycemia and NAS. In NAS, it is caused by neurological excitability due to opioid withdrawal, leading to tremors and hypertonia, which improve with soothing measures such as swaddling.
- Skin Color: Mottling is a frequent sign in neonates experiencing opioid withdrawal due to autonomic dysregulation. The absence of cyanosis or jaundice indicates that the mottling is due to withdrawal rather than an underlying pathology.
- GI Assessment: Loose stools and hyperactive bowel sounds are typical signs of NAS, caused by increased gastrointestinal motility due to withdrawal from opioids.
Hypoglycemia
- Jitteriness: Hypoglycemia is characterized by neuromuscular instability, leading to jitteriness. However, in this case, the newborn’s blood glucose level of 45 mg/dL is within acceptable neonatal range, making NAS a more likely explanation.
- Temperature, Skin Color, and GI Assessment: Hypoglycemia does not typically cause mottled skin or loose stools, making these findings more consistent with NAS.
