Which of the following statements about Group B Streptococcus (GBS) in pregnancy is true?
GBS can only be transmitted to the baby during cesarean delivery.
GBS is a common bacterium found in the vaginal flora of women and is harmless in all cases.
Screening for GBS is typically performed at the first prenatal visit.
Intravenous antibiotics during labor are recommended for GBS-positive mothers to prevent neonatal infection.
The Correct Answer is D
Choice A rationale
GBS can be transmitted to the baby during both vaginal and cesarean deliveries if the mother is colonized with the bacteria. It is not limited to cesarean sections, hence why appropriate screening and treatment are essential.
Choice B rationale
GBS, although often harmless in the general population, can cause severe infections in newborns. This bacterium can be a source of severe neonatal infections like sepsis, pneumonia, and meningitis, necessitating preventive measures during pregnancy and delivery.
Choice C rationale
Screening for GBS is typically performed between 35 and 37 weeks of gestation, not at the first prenatal visit. This timing ensures accurate detection of the bacteria closer to the time of delivery.
Choice D rationale
Intravenous antibiotics during labor are recommended for mothers who test positive for GBS to prevent transmission to the baby. This intervention significantly reduces the risk of neonatal GBS infection.

Correct Answer is B
Explanation
Choice A rationale
Copious vernix is typically found on preterm newborns, not those born post-term.
Choice B rationale
Dry, cracked skin is a common finding in post-term newborns due to prolonged exposure to amniotic fluid.
Choice C rationale
Decreased subcutaneous fat is more likely in preterm newborns, while post-term newborns might lose some fat due to nutrient depletion.
Choice D rationale
Scant scalp hair is more common in preterm infants, whereas post-term infants usually have more developed hair. .
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale:
Rapid weight gain during pregnancy, especially when accompanied by other symptoms, can be a sign of preeclampsia. This condition is characterized by high blood pressure and often occurs after 20 weeks of gestation. Reporting rapid weight gain is important for early detection and management.
Choice B rationale:
Visual disturbances, such as blurred vision, can be a warning sign of preeclampsia. It indicates potential neurological involvement and requires immediate evaluation to prevent complications for both the mother and the fetus.
Choice C rationale:
Elevated blood pressure readings are a critical sign of preeclampsia, a condition that can lead to serious health complications for both the mother and the baby if left untreated. Reporting elevated blood pressure is essential for early intervention and management.
Choice D rationale:
While the respiratory rate is slightly elevated, it is not as critical an indicator of preeclampsia as the other findings. In this case, the focus should be on more concerning symptoms, such as blood pressure and visual disturbances.
Choice E rationale:
Hyperactive deep tendon reflexes (3+) are a clinical sign of preeclampsia. The absence of clonus is a reassuring sign, but the presence of hyperactive reflexes warrants further evaluation and monitoring.
Choice F rationale:
The fetal heart rate (FHT) of 148/min is within the normal range (110-160/min) and does not indicate an immediate concern that needs to be reported. The nurse should focus on the maternal symptoms that suggest preeclampsia.
