Which of the following statements about Group B Streptococcus (GBS) in pregnancy is true?

A.

GBS can only be transmitted to the baby during cesarean delivery.

B.

GBS is a common bacterium found in the vaginal flora of women and is harmless in all cases.

C.

Screening for GBS is typically performed at the first prenatal visit.

D.

Intravenous antibiotics during labor are recommended for GBS-positive mothers to prevent neonatal infection.

Answer and Explanation

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 A

Explanation

Choice A rationale

A boggy and displaced fundus typically indicates bladder distention. Assisting the client to void can help relieve bladder distention, allowing the uterus to contract properly and

reducing the risk of postpartum hemorrhage.

Choice B rationale

Asking the client to rate her pain is important, but it does not address the immediate issue of a boggy, displaced fundus, which suggests bladder distention.

Choice C rationale

Encouraging the client to move to the left lateral position might help with blood flow and comfort but does not resolve the issue of a boggy fundus due to bladder distention.

Choice D rationale

Kegel exercises strengthen pelvic floor muscles but do not address the immediate concern of a boggy, displaced fundus caused by bladder distention.

Correct Answer is A

Explanation

Choice A rationale

Uteroplacental insufficiency leads to late decelerations, which are characterized by a gradual decrease in fetal heart rate after the peak of a contraction. This indicates compromised blood flow between the uterus and placenta, affecting the fetus.

Choice B rationale

Umbilical cord compression usually causes variable decelerations, not late decelerations.

Choice C rationale

Maternal bradycardia does not cause changes in fetal heart rate patterns like late decelerations.

Choice D rationale

Fetal head compression causes early decelerations, which coincide with contractions, not late decelerations.
