A nurse is reinforcing teaching with a client who tested positive for group B streptococcus B- hemolytic (GBS) during a prior pregnancy and is at 30 weeks of gestation. Which of the following statements should the nurse make?
“This infection can cause your baby to experience hearing loss at birth."
“If you test positive for GBS, the provider will need to perform a cesarean birth."
"You will be tested again for GBS at about 36 weeks of gestation."
"You will take an antibiotic during the last 2 weeks of pregnancy to avoid transferring GBS to your baby."
The Correct Answer is C
A: This infection does not directly cause hearing loss at birth. Hearing loss in newborns can be associated with genetic factors, birth complications, and certain infections, but GBS is not known to be a direct cause of hearing impairment.
B: A positive GBS test result does not necessitate a cesarean birth. The standard management for GBS-positive mothers is the administration of intrapartum antibiotic prophylaxis, not cesarean delivery, unless there are other obstetric indications.
C: Testing for GBS is typically done between 36 and 37 weeks of gestation because this timing is close to delivery, when the test results are most predictive of the baby's risk of exposure during birth.
D: Antibiotics are not given during the last 2 weeks of pregnancy to prevent GBS transmission. Instead, they are administered during labor to ensure effective levels of the drug during delivery, which is the critical period for preventing transmission to the baby.

Correct Answer is A
Explanation
A. At 12 weeks of gestation, the uterus is typically located in the suprapubic area. The fetal heart tones can often be detected in this region as the fetus is still small enough that its heart tones can be picked up without interference from the mother's abdominal organs.
B. The umbilical area is not the optimal location at this stage; the fetal heart tones are generally not audible in this location until the uterus rises higher into the abdomen in later gestation.
C. Above the left iliac crest is not appropriate for this gestational age. The fetal heart tones would be difficult to detect in that area as the fetus is still quite low in the pelvis.
D. Below the liver border on the right abdomen is also not correct, as the fetal heart tones are unlikely to be found there at 12 weeks.
Correct Answer is A
Explanation
A. Left calf tenderness can be a sign of deep vein thrombosis (DVT), which is a serious postoperative complication and should be reported to the provider.
B. Moderate lochia rubra is an expected finding after a cesarean birth.
C. A urine output of 3,000 mL is within normal range and does not warrant immediate reporting to the provider.
D. Breast engorgement is an expected finding in the postpartum period, especially if the client is not breastfeeding. It does not require immediate reporting.
